A data review to supplement the UK Met Office 'Disappointing Weather Meeting'

A graphical review of 14.5 years disappointing UK weather

Guest essay by Neil Catto

A meeting today (18th March 2013) took place at the UK Met Office HQ in Exeter. See the report here: http://www.metoffice.gov.uk/news/releases/archive/2013/meeting-unusual-seasons

It was arranged to include the best climatologists and meteorologists to gain better understanding of the ‘disappointing UK weather over recent years’.

Now, that the AGW debate with regard to the relationship between CO2 and temperature has been shown to be insignificant, I can only imagine the next course of action. Listening to Roger harbinger of doom on BBC Radio 4 this morning; weird weather, extremes this and that…blah blah!

I thought I would have a look and see how unusual (oops! disappointing) it has been for the last 14.5 years at a southern UK location.

Fig 1 Average daily (24hrs) pressure Well that’s not very worrying, almost a straight linear trend. UK Pa

Fig 2 Daily rainfall duration (any hour of 24 reporting precipitation) Well that’s not very worrying either, a very small decline in rainfall duration. It appears wet every day, it isn’t of course, it’s only the large amount of information (5353 days) makes it look that way on these compacted graphs.

UK RD

Fig 3 Daily (24hrs) Rainfall volume As with rainfall duration, there is a very small linear decline. There are certainly LESS number of high daily amounts in the last 8 years (2004-2013) than the previous 6 years.

UK RV

Fig 4 Average daily (24hrs) relative humidity Getting bored with the flat line trends yet? How boringly normal the weather is!

UK RH

Fig 5 Daily (24 hrs) maximum hourly wind speeds It is getting a little windier about 2.5mph/day, but hardly anything to worry about.

UK WSx

Fig 6 Daily (24 hrs) maximum temperatures Slightly COOLER, oh dear there goes the CO2 driving temperature rise theory!

UK Tx

Fig 7 Daily (24 Hrs) minimum temperatures Yet another boring straight line trend, shaking in your boots yet?

UK Tn

Fig 8 Daily (24hrs) average temperatures Slightly COOLER, so it’s lower maximum temperatures driving the average down! And still CO2 levels continue to rise.

UK Ta

Fig 9 this is my weather ‘feel’ index This index is how the weather makes us feel. On a scale of 0-60; 0-6.9 (feel bad), tired, lethargic, miserable and despondent: >7.0 (feel good) full of energy, bright, lively and dynamic. As ‘disappointing’ is an emotion and this index is a measure of emotion, it shows the weather has been making us feel a little worse.

UK X0

There has been less hours of sunlight.

UK S

I know the comments have been a bit cynical and light hearted but honestly where is the gloom, the doom, the despondency and catastrophe in 14.5 years of perfectly normal very stable weather.

On a last note, I think we can all agree the Earth has been, at stages in its past history, covered or mostly covered in glacial ice. Most people will agree that global temperatures have been much higher than today, based on paleo-geology and archaeology. Well I suggest, in very simplistic terms, the difference between the two extremes of cold and hotter, is natural variation. Is climate change real? – isn’t the change between the wide divergence of natural variation, stating the obvious.

I don’t believe this meeting was really about recent weather, it was more to do with credibility and reputations.
Remember the models, http://www.bbc.co.uk/sn/climateexperiment/theresult/resultsataglance.shtml
“UK temperature
The UK should expect a 4°C rise in temperature by 2080 according to the most likely results of the experiment.
Heatwaves are on the rise and, by 2080, summer temperatures of 40°C will be common. Winters will also be warmer.
UK rainfall
Summer rainfall is set to decrease and the UK can expect more frequent droughts
Winters will bring less snow and more rain, especially in the north and west. Storms will be more frequent and more severe.”
Basically we were to expect a northward movement of weather with Britain experiencing a Portuguese or Moroccan climate

Why is it disappointing? Didn’t they cause the environment-destroying wind turbines to be built to remove CO2 from the atmosphere so that it wouldn’t be hotter with more drought ? In other words, isn’t cooler and wetter what they wanted ?
They collectively don’t know if they’re having a shit or a haircut.

I am just an ordinary meteorologist, trained by the UKMO, worked for them for 10 years, a Fellow of the Royal Meteorological Society and took my career thereafter in another direction. For the last 15 years on a daily basis I have been archiving REAL (not manipulated) weather data. Using these data I have been researching how it affects living organisms, from mitochondria (bacteria) to humans. There is nothing alarming about what is happening to the global weather, it is all within the vast realms of natural variation.

My father was also a meteorologist (and atmospheric Physicist) and I do think its was always “yawn”. Nothing unusual happening abnormal in weather or climate. Basically been there seen it many times and its extremely boring and repeatable. If you actually could be bothered to look at daily weather in cities such as Brisbane Australia weather events are extremely repeatable even to the day. For example the Ekka Festival beginning of spring, was always cold,windy and a wet weekend. I saw the event repeat at least 14 out of 20 years to the date! I think to non-weather people (especially ardent young warmistas), looking at a weather map sometimes it looks like a monstrous storm, drought or whatever low or high system is coming to kill us all! Its all the lines, arrows, numbers and colors me thinks.. like this map for example which re-inforces their fears of AGW

People often say that today’s weather is “worse than anything they remember”.
——————————-
One can search the historical archives and find books and papers from the middle ages where folks complained that the weather was “worse than anything they remember”. Probably written on Babylonian cuneiform tablets as well. But back then most people thought it was punishment from god for their sins.

What I’m seeing here (Atlanta, GA.) is that the local news, and the Weather Channel, are pushing everything as ‘extreme,’ ‘unseasonal,’ etc….
—————————————-
Same here in Philadelphia PA. Everything is “extreme” anymore. We had a “heat wave” a few weeks back. 90F for 3 days in a row! And then it was 65F and raining for the next 7 days. Oh but did we have a heat wave! Almost didn’t survive!
A week or so ago they scared everybody with a massive storm, flooding, winds, tornadoes, People didn’t come to work. I said one station was even predicting Chupacabras. Nothing but a little rain fell.
I think people tire of this like the story of the little boy that cried wolf.

Dear Met Office,
here’s a free clue. Until you can get the next month right don’t forecast the next 10 years. You are only going to look like an inept money pit.
Yours,

1998 was the year I started collecting the weather data for my research. Nothing more sinister.

The resolution of these graphs cover over 5000 individual days. Expanding the resolution from the original data shows all sorts of patterns.

‘UK disappointing weather’ – (not so) clever way to deflect disappointing forecasts. Man this says oodles. I guess the forecasts were fine but the weather was disappointing. Taking this a bit further, how is the weather disappointing? Would it have been BETTER if we had your tropical summers and deep droughts that you were forecasting? Indeed, were you HOPING for such “extreme weather” things to happen? Weren’t you bemoaning the imminent onset of snowless winters that your poor children would only know from Christmas cards and tales of the old folks. Hey, the fact that it went the way you thought was best for the planet should not be a disappointment.

For both the Met Office and CRU I am proposing a new regime of ‘Payment by Results’ for all funding including wages.
Both agencies to be tasked to make forecasts and all payment will directly depend on the accuracy of the results. Forecasts will contain no passive language, error ranges to be strictly limited.
Met Office forecast will run up to 3 months into the future, CRU funding will depend on the accuracy of all forecasts and reports from the last 15 years to the present and weighted to reflect the publicity they enjoyed.
I believe such minor changes would improve all future forecasting in both accuracy and focus.

Good insight.

If the weather is back to what it was before CAGW and the greenies are still not happy, what weather will they be happy with? Is there any condition of weather that can co-exist with greenies?

I remember it well too. We walked into caves that were normally sumps you had to dive and I managed to get a sunburn despite spending most of my vacation in the UK underground.

Ken Hall said: “There were definitely a lot more floods where I live in Cumbria, than there had been for years and the farmers I speak to up here have never known weather as bad for a very very long time. Likewise the unusual cold winter and spring.
No, this weather is not unprecedented, as some have tried to claim, but it is unusual. ”
No its not “unusual” at all Ken.
And the reason its not unusual is simply because the time frame youre measuring it over is only within the lifetime of a pesky carbon emitting human, its too short.
If you measure the patterns over a couple of 100 thousand or even a million years then youd see trends and changes because youd have greater resolution of the data, you have no resolution at timescales of 10’s of years, so no, its not “unusual” in the slightest.
Try measuring a 1 hz signal on an oscilloscope using the 10khz timebase and see where it gets you- straight lines anyone?
No wonder the [sarc] “best scientists in the field”[/sarc] dont know whats going on, not enough resolution to have a proper clue.

First they forecast doom and gloom.
When the forecast is wrong, do they cheer and say “Verily, the Gods have spoken. Let us throw another stack of taxpayer money virgin on the fire”?
No, they say “Oh noes, it’s worse than we thought!”
I can see it now. It’s Burn vs Freeze.
The new left vs right.
Which will kill us all first?
How can people live their lives seeking the down side of everything in life?

On the BBC weather site, people type in their local post code and it tells you what’s going to happen. We live in southern end of Lincolnshire – which is on the east side of the UK about a third of the way up.
On Saturday 15 June, the MET Office forecast for our area for this coming Sunday 23 June was “Cloudy, max 21C”.
Then the next day, Sunday 16, their forecast remained the same – this coming Sunday was still “Cloudy, max 21C”.
On Mon 17, forecast for this Sunday changed to “Cloudy with sunshine and rain, max 21C”.
Tue 18, forecast for this Sunday “Cloudy with sunshine and heavy rain, max 19C “.
Wed 19, they forecast “Cloudy with sunshine and heavy rain from 1pm, max 14C”.
Today, Thurs 20, “Cloudy, sunshine, heavy rain from 10am, showers all day, max 15C”.
What’s the betting that this Sunday 23 June will actually turn out to be beautiful, sunny and dry with azure skies and not a single cloud in sight. And, just remind me again, how much did the MET Office’s computer cost?

GeeJam, last Friday the BBC said Saturday in SE England would be fine with heavy rain in Sunday. At lunchtime on Saturday, they still said the same. It was peeing down at the time. Sunday was nice.

Hate to play Devil’s Advocate, but why was 1998 chosen as the starting point?
>>>>>>>>>>>>>>>>>>>>>>>>>>
You have it in reverse order.
FIRST:
The IPCC expected that global temperature would rise at an average rate of “0.2°C per decade” over the first two decades of this century. Half of the rise would be due to atmospheric GHG emissions which were already in the system and as a result of the “slow response of the oceans.” That was the expectation and it says so right there in IPCC AR4 (2007) Chapter 10.7

The multi-model average warming for all radiative forcing agents held constant at year 2000 (reported earlier for several of the models by Meehl et al., 2005c), is about 0.6°C for the period 2090 to 2099 relative to the 1980 to 1999 reference period. This is roughly the magnitude of warming simulated in the 20th century. Applying the same uncertainty assessment as for the SRES scenarios in Fig. 10.29 (–40 to +60%), the likely uncertainty range is 0.3°C to 0.9°C. Hansen et al. (2005a) calculate the current energy imbalance of the Earth to be 0.85 W m–2, implying that the unrealised global warming is about 0.6°C without any further increase in radiative forcing. The committed warming trend values show a rate of warming averaged over the first two decades of the 21st century of about 0.1°C per decade, due mainly to the slow response of the oceans. About twice as much warming (0.2°C per decade) would be expected if emissions are within the range of the SRES scenarios.

SECOND:
The NOAA falsification criterion is on page S23 in its 2008 report The State Of The Climate

ENSO-adjusted warming in the three surface temperature datasets over the last 2–25 yr continually lies within the 90% range of all similar-length ENSO-adjusted temperature changes in these simulations (Fig. 2.8b). Near-zero and even negative trends are common for intervals of a decade or less in the simulations, due to the model’s internal climate variability. The simulations rule out (at the 95% level) zero trends for intervals of 15 yr or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate.

This means the climate models show “Near-zero and even negative trends are common for intervals of a decade or less in the simulations”. However the climate models RULE OUT “(at the 95% level) zero trends for intervals of 15 yr or more”. (H/T to Richard S Courtney link )
So counting backwards to see if the NOAA criteria is met you get 2013- 15 years = 1998.
We have had (at the 95% level) zero trends for more than 17 years whether or not one interpolates across or extrapolates back across the 1998 ENSO peak. (Santer used a criteria of 17 years of no warming.)
Now that the 1998 ENSO peak can no longer be used to say “SEE, the earth is WARMING, be very afraid” and can be used to say we are cooling or at least showing no significant warming, the peccatogenesists are jumping up and down and screaming that the 1998 ENSO peak doesn’t ‘count’ and ‘Deniers’ are cheating. You can see this as they dance The Post Modern Mamba in response to Courtney nailing them with facts in WUWT Has Global Warming Stalled?
I think that WUWT readers might enjoy this snippet about the The Post Modern Mamba

The Post Modern Mamba is a dance routinely performed in AGW Land. It goes like this. A sceptical post is “rebutted” using all the tricks of the trade available to post-modern AGW cultists. They HAVE to use these tricks, since they can’t possibly argue the science. If you doubt this, we’ll take an in-depth look at some of FORM’s answers / tactics in a moment.
The outstanding feature of the Post Modern Mamba rebuttal is that is it all seems so reasonable. That’s because it usually is. At least at first glance. And at least as long as you don’t look too closely at what was being debated in the first place. Close examination usually reveals that the rebuttal, at best, usually only has some passing association with the actual debated subject. Often it has no bearing at all and by sleight of hand is actually about something entirely different….

Yes, you are correct. I am retired and now do entertainment for kid’s birthday parties. It has been very cool this spring and I normally ask people how they like “the Global Warming” So far in the last couple of years I have only had one zealot try to convince me that “Global Warming” was causing the global cooling we were seeing. I usually get a Humph or a laugh.
Even more heartening is people are paying a lot more attention to what is happening in the economy as a result of the actions of the politicians. I have seen a big awakening of the general population since ~ 2008 and people are starting to question and dig for information.

the posting of videos in the comments section is most annoying as they all start playing at once and none of them seem to be pertinent, i.e. everything Janice Moore posts.
