Guest opinion: Dr. Tim Ball
The east coast of America experienced a storm surge, heavy rain, flooding, and strong winds that blew down trees. Also, regrettably, a few people who live in the area lost their lives. These are all normal events, except the loss of lives which only began after people occupied the region. In fact, the total impact was below the normal for long-term averages of hurricanes in this region. Being surprised by the impacts of a hurricane in this region is like being surprised by flooding when you live on a floodplain.
The whole story of hurricane Florence underscores the degree of corruption of natural events for a political agenda. All the players, from the bureaucrats at the National Oceanographic Atmospheric Administration (NOAA), through the media, and the historical role of Insurance companies, created misinformation, misused and omitted data, to nakedly distort the reality. They took a perfectly normal, well within even brief historical sequence event, and turned it into a never before seen monster.
The role of NOAA in this is further evidence of their collusion in the deception that is anthropogenic global warming (AGW). With Florence, they got almost everything wrong. The computer model predictions of the path and strength were wrong even in such a short distance and in 48 hours; a period for which they claim a high level of accuracy. They claimed the hurricane path was very unusual because it was further north than usual. No, it wasn’t. I was in Bermuda in the early 1960s when we were forced to evacuate because of a hurricane moving in.
On Wednesday the 12th I did four radio programs across America explaining what was wrong with the hype and predictions about hurricane Florence. By Wednesday evening they already downgraded Florence from a Category 4 to a Category 2, and it came ashore barely as a Category 1. In fact, it was amusing to see how long they continued to report it with wind speeds of 75 mph because if it was 74 mph, it was no longer a hurricane. NOAA control the wind speed determinations with their estimates from one or two flights above the hurricane from which, using models they estimate surface speed. We know these are consistently higher than reality, but a higher speed allows for a higher hurricane category and greater media attention.
The major story with Florence was the level of exploitation and hype by every segment of society all driven by the so-called experts getting it wrong. In just that one small region of the world with a reasonable supply of information, several computers gave different paths and potential outcomes. The idea that a cone of potential paths is somehow helpful or is an improvement is laughable. All you have to do is look at the tracks of all previous hurricanes and with a known starting point draw a cone. It doesn’t need a computer. The truth is the forecasters got the most important parts of the dynamics wrong.
Apparently, the NOAA forecast ignored three major mechanisms. One was the presence of colder water as Florence moved north. The fuel source for a hurricane is the latent heat of evaporation carried up and released as sensible heat after condensation. Estimates are that a moderate hurricane, like Florence, evaporates 2 billion gallons of water an hour. This is why, when the system moves over land it dissipates very quickly. Another was the three-dimensional dynamics of a system that stretches from the surface to the Tropopause. That very distinct boundary is twice as high over the Equator (approximate average, 18 km) as it is over the Poles (approximate average, 8 km). This means the system gets flattened out as it moves north, which explains why Florence became much wider. As it widens the wind speed diminishes in the opposite effect to a skater spinning with arms spread spinning slowly and increasing spin rate as the arms are drawn in. Very simply, the speed of rotation is determined by the radius of the mass from the axis of rotation. The combination of the energy in the system and the reduced speed of rotation served to alter the path the system takes. The Coriolis Effect is changed, which is partly why they got the direction wrong in such a short distance.
As Florence’s Category decreased the wind speed decreased but also the atmospheric pressure decreased. At 955 mb it was above average, but this increased with the category change. This is very important because a major cause of the surge is the weight of the atmosphere pushing down on the ocean surface. With low pressure the surface bulges up and it moves along with the system. When this long low amplitude wave reaches shore it becomes the tidal surge. It is amplified on the windward side of the hurricane center and also if it coincides with high tide. These factors should be part of the estimate of flooding potential.
The media distortions were fully represented by the reporter pretending to lean over because of the wind when people in shorts stroll casually past. Unseen in all this, is the role insurance companies played in this history of this exploitation. They did far more to exploit the deception of AGW or profit than any energy company.
I was reminded of this with the misinformation and unadulterated exploitation of hurricane Florence by alarmists and the media. Attempts to present the hurricane as abnormal and link it to climate change were naked and almost desperate. It reached a nadir when the Washington Post wrote,
Yet when it comes to extreme weather, Mr. Trump is complicit. He plays down humans’ role in increasing the risks, and he continues to dismantle efforts to address those risks. It is hard to attribute any single weather event to climate change. But there is no reasonable doubt that humans are priming the Earth’s systems to produce disasters.
This is a reference to Trump’s withdrawal from the Paris Climate Agreement. A good article about this distortion was presented by James Agresti on WUWT. I will only add two points. Bjorn Lomborg calculated that even if fully implemented the Paris Agreement would make no difference. He wrote,
The climate impact of all Paris INDC promises is minuscule: if we measure the impact of every nation fulfilling every promise by 2030, the total temperature reduction will be 0.048°C (0.086°F) by 2100. (His emphasis).
This reduction is within the error of the estimate, and it incorrectly assumes that CO2 is causing warming. To add insult to injury, China, Russia, and India, combined adding far more CO2 and not required to reduce production until 2030, are demanding money from the Green Climate Fund approved in Paris.
A hurricane is normal and is only defined as disastrous because of the damage, death, and destruction it does to humans and their constructions. Like the tree falling in the forest, all the other impacts of flooding and trees blown would occur even if humans were not present. Over time more and more people moved into the hurricane-prone region and suffered the consequences. All of the more severe consequences resulted from the enabling and false sense of security created by government and insurance companies. For example, two of the greatest loss of lives involved Galveston, Texas and New Orleans. In 1900, an estimated 12,000 people drowned in Galveston because an earthen dam failed. Authorities dramatically downplayed the loss of lives for political and economic reasons. In 2005, hurricane Katrina came ashore at New Orleans, and 1833 people died, most from the flooding. They were behind a dike that the US Army Corps of Engineers sought to fortify but were blocked by environmental groups. Katrina, like Florence, was hyped and even today Wikipedia still says,
Hurricane Katrina was an extremely destructive and deadly Category 5 hurricane that struck the Gulf Coast of the United States in August 2005.
In fact, Katrina was barely Category 3 when it came ashore.
Before Katrina, the most expensive in terms of claims for damage ($108 billion) was hurricane Andrew at $26.5 billion in 1992. This is important because the multiple small insurance companies were unable to satisfy all the claims. As a result, a few insurance companies were created to provide insurance to smaller companies, called re-insurance. They offered insurance to the smaller companies in the event of another similar overwhelming disaster. There are hundreds of them today because it is such a lucrative business. I know this because a former student of mine who is a manager handling a large portfolio (a few billion) is always looking for companies with very low overheads and extremely high cash assets. He identified a few for consideration but never invests without talking to management. He discovered that a short list of the largest early players, such as Swiss-Re and Munich-Re, established bases in Bermuda. He arranged to visit with a few of them and invited me to talk with them about how they build hurricane forecasting into their strategies.
The businesses were based in Bermuda because of a tax-free deal. Bermuda benefitted from the large amounts of cash moving through their banking systems. Ironically, the majority of staff at these companies in Bermuda were young men and women formally working for Lloyds of London. They all lost their jobs after Lloyds was unable to manage claims mostly from oil tanker spills.
As I recall, we visited with at least four companies and asked them all the same questions about hurricanes and research science and forecasting. I asked them if they followed the work of the late Dr. William (Bill) Gray at the University of Colorado. In every case, they said they did not pay any attention to weather or climate forecasting in general and hurricane forecasting specifically, and none knew about Dr. Gray. I asked them how they determined rates from year to year if they didn’t consider research and expert predictions. One answer represented the overall view, ‘We charge what the market will bear.’
The shameless part of all this was the overt activity by some of these companies, but especially Swiss-Re in promoting its business. They joined the Chicago Climate Exchange that was central to carbon credits trading and had Maurice Strong on the Board. They claimed they joined to “facilitate reduction of carbon emissions.” You could argue their intent was genuine as expressed here
Swiss Re uses its core skills in risk assessment and risk transfer to address sustainability challenges, including climate change. While its specialists foster the exchange of relevant knowledge within the company, they also collaborate with external experts to achieve a better understanding of environmental issues.
The trouble is even minimum research showed carbon credits increase CO2 in the atmosphere. Why didn’t they find this?
A UN-endorsed carbon offset scheme designed to reduce emissions has actually increased them massively, a study by a green think tank has found.
As well as pumping much as 600 million tonnes more greenhouse gases into the atmosphere, the carbon credits scheme has been abused by countries like Russia and the Ukraine which have used them as a money-making scam.
A simple search also raises this article title, “Why does IDEAcarbon believe that carbon offsets reduce emissions?”
Then there is Swiss Re sponsorship of a documentary (here). They explain
“As part of our core focus on sustainability, Swiss Re has been committed to actively raising awareness of climate change issues for well over a decade and we believe that ‘The Great Warming’ is an important step forward,” said Mr. Simon Lam, General Manager for the Hong Kong Branch of Swiss Re.”
Here is a press release about the movie that pushes all the propaganda buttons.
Narrated by Alanis Morissette and Keanu Reeves, The Great Warming is a dramatic film about climate change that sweeps around the world to reveal how a changing climate is affecting the lives of people everywhere. It has been called “the best film about global warming ever shot,” and taps into the growing groundswell of public interest in this topic to present an emotional, accurate picture of our children’s planet.
The Great Warming includes hard-hitting comments from scientists and opinion-makers about America’s lack of leadership in what is certainly the most critical environmental issue of the 21st century, as well as new scenes documenting the emerging voice of the America’s faith communities urging action on climate change.
Why do they need to say “our children’s planet? What do “faith communities” have to do with climate change? The answer is because it is all about the political and emotional exploitation of natural events.
Perhaps the most egregious distortion created by the insurance industry was the claim that hurricanes were increasing in intensity. It turned out the data they used was the increasing cost of claims. Of course, this was almost all due to the increasing gouging for materials and labor before and after the event.
AGW is the biggest fake news story of all created and perpetuated by the bureaucrats who are the deep state. A single small moderate and normal hurricane named Florence demonstrated the level of deceptions across the social and political spectrum. We need to ask how much longer can people who consistently get their forecasts wrong, retain credibility and keep their jobs? If Upton Sinclair is correct,
It is difficult to get a man to understand something when his salary depends upon his not understanding it.
Then it will be a long time before they go, especially adding, for me, Alexander Solzhenitsyn’s even more disturbing observation that,
“To do evil, a human being must first of all believe that what he’s doing is good.”
Finally, just a couple of many questions to underscore the insanity of it all. Consider how much infrastructure could be made hurricane proof with the billions of dollars spent by the Federal government on AGW. Why aren’t there mandatory building codes for a hurricane region that has existed for thousands of years and will continue, with or without climate change?
Good post by Dr. Tim Ball.
If voting was still functional the trolls would give me the badge of honor by their down votes.
We’re having another heat wave here in drought-stricken Colorado. My personal experience has been that heat waves here are strongly correlated with Atlantic hurricanes. I’ve developed a theory that since the overall atmospheric pressure must balance, areas of extreme low pressure such as tropical systems should be associated with high pressure somewhere else. This is a simple yet interesting idea, but I have not seen it discussed elsewhere.
One of the implications of this theory is that oceanic heat is converted into the kenetic energy of convection and advection by the hurricane, then this energy is converted back into heat by the ridge. However, the ridge is far inland in an arid area, so this heat does not evaporate much water and does not participate in further iterations of the convective storm cycle. It is here, in the ridge, where it is finally dissipated into space by radiative cooling.
The upshot here is that a particularly active tropical storm season would be indicative not of global warming but of a far deeper and more structural trend towards global cooling, as the comparatively stable oceanic heat is converted first into mechanical motion and then into dry atmospheric and surface heat, and finally into radiation.
The deserts are the great radiators of the globe. If we assume that the solar constant doesn’t vary significantly, then if the deserts are getting hotter, that means that the oceans are getting colder.

Remo , I was wondering whether one can take your ideas about the energy contained in individual hurricanes a bit further. One of the current points of disagreement is whether the present Modern Warming Period (ModWP) is making the frequency and severity of hurricanes (and for purpose of discussion lets restrict to the Atlantic variety) greater or less.
Suppose one could sum up all the kinetic energy and its excess enthalpy to provide a total energy figure that increases from inception off the west coast of Africa or mid ocean until its landfall in the eastern US or Caribbean.
Instead of plotting frequency of landfall of hurricanes of varied category, which is sometimes contentious, look at the total storm/ hurricane energy per season for the pre ModWP and for recent decades to establish whether there is a connection with the (very) slight recent warming of the Atlantic.
The regulars, with real knowledge of meteorology , will now say that that has been done since , oh, about 1803. In which case what do the plots look like?
As is well documented, previously the (now disappeared) global cooling scare was previously blamed for a deterioration in global weather.
I think the truth is that severe weather events arise when you have a large temperature contrast, however that arises.
I have heard that with the right statistical model some hurricanes have actually saved lives.
To the query as to whether hurricanes might save lives: I saw reports attributing 2-3 traffic fatalities to hurricane Florence. I wonder how many traffic fatalities normally occur over the affected area during the same time period. There was a lot less driving going on…

From the article: “Another was the three-dimensional dynamics of a system that stretches from the surface to the Tropopause. That very distinct boundary is twice as high over the Equator (approximate average, 18 km) as it is over the Poles (approximate average, 8 km). This means the system gets flattened out as it moves north, which explains why Florence became much wider.”
That’s interesting. I saw a graphic on tv the other day showing that Hurricane Sandy was estimated to be 1,000 miles in diameter, while Hurricanes Katrina and Florence were each about 500 miles in diameter.
So is Hurricane Sandy’s more northerly course the cause of it being so wide? I would guess the Northeaster that merged with Sandy when it made landfall added to Sandy’s size.
Tim and Tom,

I liked your post Tim, except this quoted part made me doubt your emphasis it criticizing forecasts and path-intensity models. I disagree about the path forecast criticism. I thought it was very well forecast for path (but I’m not in the USA and don’t see the media source dirge you see).
The US Navy’s site “Navy/NRL TC_PAGES Page” ( https://www.nrlmry.navy.mil/TC.html ) provides a forecast that appears to broadly mirror the European ECM model output for path but includes their own wind-field intensity forecast and mapping. IMO, the US Navy’s method is very usable and is quite reliable, sufficiently accurate over time for planning purposes. It exists because the USN determined it required a reliable 5-day forecast to position ships and aircraft well in advance of a storm, thus instituted an effort to provide that level of 5-day forecast accuracy–and it had to be globally accurate. It was astonishingly accurate at predicting the landfall location and intensity of Katrina, 5-days from its second landfall. That’s when I realized their predictive forecast was working. The path for Florence worked very well also, as did the ECM model in general, though the intensity and central pressure forecast aspects did not.
It seems it was the official, private and commercial ‘diversity’ models and ‘inclusiveness’ of models that seem to have produced the appearance of inaccuracy in forecast tracks, plus media nonsense. That’s why I always bypass TV forecasts (or in my case, BOM forecasts) and just go to the US Navy page instead. So enough of that, on to area and intensity.
Cyclonic storms routinely increase (rapidly) in area as they intensify regardless of (tropical) latitude. I’ve observed an intense warm-core cat-4 tropical cyclone at 27 degrees south. A large initial low will usually generate a spread-out cyclonic wind field and cloud area as it intensifies. Likewise small initial lows tend to produce small area wind fields and a central-dense-overcast that is much smaller for most of the life of a storm. They can grow and shrink but initial conditions at the lower levels have a large impact on storm area as it intensifies and moves pole-wards.
The USN page linked also provides a very useful track map that depicts the likely sector expansion and shrinkage of a storm’s radius and wind levels during the 5-day forecast. In general, it shows a common trend of a strengthening storm getting bigger, and a weakening storm getting smaller, irrespective of latitudes and troposphere elevation.
That is not to say troposphere has not significant impact. But Tropopause elevation is a dynamic factor in such a storm as the deep convection cloud-tops over such a large area, can lift the local Tropopause elevation as the system “makes its own weather”–the atmosphere (being predicatively modeled in computer) responds to the atmosphere that was, and is. Resulting cloud-tops and humidity in upper levels show that the cyclonic storm convection strongly impacts all aspects of upper troposphere, as cloud-tops exceed the normal Tropopause elevation for that area and latitude for the season.
Tropopause elevation may suppress the strengthening of a storm some with higher latitude of the path, but it’s less likely to be a major factor in dropping cyclone strength. Plus it’s fairly clear that upper level pressure is what directs the path, as it did in the case of Florence, via pushing it for NW to SW just before landfall. So Tropopause elevation affecting Coriolis input, was not a dominant aspect of resulting path for Florence.
However the latitude of Wilmington is 34.2 north, well outside the tropics, so Tropopause may further squeeze the already large storm to spread-out more. You are most likely correct about that.
But such squeezing from above does not mean it can’t maintain its strength or intensify, if other conditions are favorable.
In this case other conditions were not favorable for maintaining strength to landfall as a large area of descending air over Georgia and South Carolina inserted drier air closer to the lower and mid level which fed into and wrapped around the storm during the final 12 hours before landfall, and the result was it rapidly atrophied the storm’s central dense overcast storms, plus its southern and eastern margin inflow bands. SST was about 28 degrees C in the affected area and could not compensate to as moisture to overcome the dry air input to the core. It thus could not maintain its central pressure and outflow as the convection intensity dropped.
Thus it weakened out quickly to Cat-1 before landfall.
Thank you for the the article, Dr Bell.
Sccheech. sorry, “Dr Ball”.
A Freudian slip? No. He actually once again rang the bell of common sense.
WOW – someone who actually presents a knowledgeable & factual reply of the tropical cyclone situation instead of all these air-chair weather watchers with a physics book in their lap who like to opine as if they know anything about the science of meteorology. Very good WxCycles!
“It is hard to attribute any single weather event to climate change. But there is no reasonable doubt that humans are priming the Earth’s systems to produce disasters.” What a stupid statement. If it is hard to attribute any one single weather event to climate change, by what measure would you use to attribute one of them may be do to climate change? In other words, there is no practical way to attribute any of them hence it is not reasonable to say humans are “priming Earth’s systems to produce disasters”.
Damn, even the movie industry is in the exploitation business, as evidenced by a line in the new Predator movie that I just went to see an hour or so ago.
There’s a line in the dialogue about how long Earth has before climate change reduces it to a hothouse that will be more favorable to the predators.
No. They. Didn’t !
And we wonder why people like Paul McCartney are so confused.
Brian Aldiss was way in front of this.

Thank you Tim Ball for another highly informative article.
It is particularly helpful to have a recognized climate expert like Dr. Tim Ball, who can dismiss all the nonsense we see on the news about global warming and climate change hysteria.
The news media have NEGATIVE CREDIBILITY whenever they comment on climate issues –they are spewing a pack of lies that support their political agenda.

IT’S TIME TO FIGHT BACK – WARMISTS ARE LYING SCUM, TRYING TO STEAL YOUR MONEY AND CONTROL YOUR LIFE. BOYCOTT THEM NOW!”
Yes, yes the world’s experts in climate science are incompetent liars, we know —- it makes perfect sense. Thousands and thousands of them over the decades.
No one has come along with observations and any sort of ABCD theory that can be repeatably checked out as contradicting the discoveries of climate science (and any other related Earth science) this last 150 years plus my friend.
Stands to reason, doesn’t it (sarc)
It, really really helps to have a conspiratorial mind-set … and tellingly an absence of common-sense driven by the mind-set that can manufacture a “Scum” because you don’t like the world they have discovered.
If it were me nursing you I’d call the men with the white coats.
I didn’t think shouted abuse was allowed.
Taking the whole area affected by the Florence weather system, with its several million population, can anyone estimate how many accidental deaths would normally happen, on average, in a 5 day period?
How does this compare with the 11 deaths “caused” by Florence?
IF the normal 5 day period has 20 deaths does that mean the storm saved 9 lives using the same math used in puerto rico?
Bill
Numbers would be too small combined with stochastic variability for any significance. But at least it would put the deaths in perspective.
The concept of control and the null hypothesis is disappearing from the scientific consciousness of today’s closely knit media-political and scientific establishment.
So called “gouging” is an emotive term used to manipulate people.
Prices are always a reflection of supply and demand and if they go high, it is because of increased scarcity, often due to government impediments to increasing supply, such as FEMA blocking Walmart’s attempted delivery of bottled water after Katrina.

As usual, Tim Ball’s comments about the AGW hoax are among the most cogent available and should be required reading for anyone examining the various aspects of climate change theories.
There were four National Forests and three National Parks that were thought to possibly be in the path of the storm well after it made landfall. The Cherokee, Nantahala, Pisgah, Jefferson and George Washington Forests, the Great Smokey Mountains, the Appalachian Trail and the Blue Ridge Parkway that closed some or almost all of their developed recreational facilities and many access points and roads on Wednesday and Thursday of this past week because of the devastation expected from this ‘awesome’ storm’s violent winds and torrential rains. It ain’t happened yet as near as I can tell on Sunday, September 16th, 2018. My barometer has only fallen .4 from its high of 30.2 in the five days I’ve been carefully monitoring it. Perhaps it is well they erred on the side of caution. On the other hand, somebody might have sold them a pig in a poke named Florence.
There is a fundamental philosophy underlying much of what goes on in the world today regardless if it deals with climate change, inner city violence, poverty, the environment or any other issue dramatized by our mainstream media and our politicians.
It is a wholesale endorsement of this idea: If you believe your cause is good, noble or profitable, then the end justifies the means. If the means is lying, exaggerating, falsifying or even damaging someone’s reputation by doing these things for your cause, then it is justified.
This philosophy was codified by Sal Alinski in his “Rules for Radicals” published many years ago when he devoted a whole chapter to justify such tactics as “—anything is fair in war”.
The problem is once you do this, you eventually change the noble “ends” through the principle of unintended consequences, such as ignoring real and solvable environmental problems.
Dr. Ball, the university associated with Dr. William Gray is Colorado State University in Fort Collins, Colorado, (the Rams) and not the University of Colorado in Boulder (the Buffaloes). The CSU / CU distinction is a minor one except to all the people at these two schools, which are rivals in sports, recruiting, fund-raising and other more symbolic activities.

I believe you have made two errors.
1 “As Florence’s Category decreased the wind speed decreased but also the atmospheric pressure decreased. At 955 mb it was above average, but this increased with the category change.”
Surely this should read:
“As Florence’s Category decreased the wind speed decreased but also the atmospheric pressure increased. At 955 mb it was above average, but this increased with the category change.”
2 “the majority of staff at these companies in Bermuda were young men and women formally working for Lloyds of London.” “formally” means that they were still nominally on Lloyd’s books as employees. I believe you mean “formerly”.

I’m pretty sure that had Clinton been president, a study by Harvard would not have concluded that Maria killed 4645 people in Puerto Rico, instead of 65, nor would GWU have found that almost 3000 died as a result of the storm.
Regarding your last sentence, why doesn’t the government mandate hurricane-proof building? Because no one would move there, there would be sticker shock. I lived on Guam which is hit much more often with stronger tropical cyclones and no one has a place to go. Your house is your typhoon shelter. The houses are built with concrete block and “200 mph coconut proof” windows and all the power poles are made of concrete. I believe that if there were no place for the residents of the east & gulf coast to go in the event of a hurricane, and if there were no one to bail them out with insurance that houses would be built to withstand hurricanes, and people would stop building in floodplains.
Changing the direction of the jet stream over the Atlantic followed on increase in the geomagnetic activity at the end of August 2018.

Geomagnetic activity is still high.

A jagged hole in the sun’s atmosphere is facing Earth and spewing a stream of solar wind toward our planet. Estimated time of arrival: Sept. 17th. Because the gaseous material will reach Earth only a few days before the onset of northern autumn, it may be extra-effective at sparking auroras–a result of “equinox cracks” in the geomagnetic field.

While I agree with the thrust of your article, there are some errors. First, hurricanes start at 74 mph, but we like to round to the nearest 5 mph. Second, surface winds measured by aircraft are generally pretty accurate at both the surface and at flight level. The WC-130s are equipped with Stepped Frequency Microwave Radiometers, (SFMR) which measure the ocean surface winds with reasonable accuracy under most conditions. Dropsondes equipped with GPS also deliver accurate measurements of wind (and rain rate) from flight level down to the surface. Flight level winds can also be determined using the aircraft GPS, with fine resolution in space and time. All this to say that winds are usually measured quite accurately these days, and the only question is how representative these measured winds are of the storm’s max sustained winds. I might add that the WC-130s do not fly above the hurricanes, they normally penetrate at a pressure altitude of 10,000 to 12,000 feet.
Now I have an important point to make here. I flew weather reconnaissance with the 54th Weather Recon Squadron (Typhoon Chasers) out of Andersen AFB Guam from July 1981 to July 1984 as an Aerial Reconnaissance Weather Officer (ARWO), and was credited with 56 typhoon eye penetrations. I also flew for 2 weeks with the 53rd WRS (Hurricane Hunters) in Sep 2008 as a mission scientist on 10 of their missions that were part of an international research project out here in the western Pacific, called TPARC. Eight of the missions were flown on Typhoon Sinlaku, and the other two were invest missions. Dr. Peter G. Black directed the effort here on Guam. Now here is the point: I am familiar with the recon business, and I can tell you that the top priority of every mission is to get the most complete, representative and accurate data possible consistent with safe flight, and get it to the forecast agencies that need it to produce the best possible forecasts and warnings. There is no political agenda, either among the flight crews or among the forecasters at NHC, which is under NOAA. No one at NHC is trying to make any hurricanes look worse than they are. The hype comes from the media.
I hate to say this, but your understanding of atmospheric dynamics seems a little weak. No, hurricanes do not expand because the trop is getting lower as the storm moves poleward. I’ve seen plenty of typhoons that expanded while staying in the deep tropics on a westerly track. Forecasting really is a little more complex than just drawing a cone from a point, and if you really did look at tracks from previous years you would know that. So how did NHC do in their forecasts? Well in Advisory 39, issued late Saturday the 8th, NHC’s 5-day forecast had Florence about to make landfall near Wilmington NC late Thursday the 13th—five days later. In fact, Florence did make landfall near Wilmington late Thursday/early Friday, and Wilmington reported a gust to 105 mph in the northern eyewall. I’d say that was pretty good forecasting. Next, the sea surface temperature was plenty warm enough in the Gulf Stream along the coasts of the Carolinas: in the lower to mid 80s F. Florence weakened primarily due to upper-level southerly wind shear that disrupted the storm structure near the center, causing the eyewall to open up, and weakening the winds. Finally, the lowering of pressure in the eye can only raise the ocean surface 2 or 3 feet at most. The main cause of storm surge is the wind, that piles up water ahead of the storm as it encounters a continental shelf. The 1900 Galveston Hurricane killed so many people because of the massive storm surge that was built up by the winds, and because of the lack of knowledge about hurricanes back then and the resulting lack of effective warnings. There was no earthen dam, by the way–check it out.
Dr. Ball, you make a lot of good points concerning media/business/gov’t hype, and concerning the fact that Florence was a perfectly normal hurricane in a normal climate. But your essay is marred by the many untrue assertions about hurricanes and hurricane forecasting, which can only undermine your main thesis. As a skeptic myself about AGW/climate change, I would urge you to be more careful.
Mike Middlebrooke –
OUTSTANDING POST!! Yet another example of knowledgeable & factual meteorological information (something sorely needed around here at times). Thank you for your service!
Just a small difference of opinion, if I may:
” Florence weakened primarily due to upper-level southerly wind shear that disrupted the storm structure near the center, causing the eyewall to open up, and weakening the winds. ”
I believe the weakening was more due to ingestion of dry air on it’s SW side. The satellite imagery (GOES-16!) did not show any blow off of upper-level clouds on the up-shear side (outflow was fairly symmetrical) nor the exposure of low-level clouds up-shear which is typical of shear events. However, wxsat imagery did show the evaporation/loss of deep convection as it was wrapping around the core. This works against the latent heat effect, cooling the core & upper-level high and weakening the system.
Similar thing happened to Katrina in the days before landfall.
Actually, that was also a big factor that ties in with the shear, which may help dry air penetrate into the center. Radar imagery showed the dry slots clearly. The shear was 20-25 kt according to NHC. Thanks for your improvement on my analysis.
