While nowhere close to Trenberth’s missing heat, it’s a nice bite sized chunk of SST. Hurricanes are heat engines, transporting massive amounts of heat from lower to higher levels of the atmosphere.
La Niña is growing too. Have a look:

So if there is a following storm as some have predicted, This may mean that the heat engine will not be there when it hits the coast?
Convection transports the largest portion of heat to the stratosphere. convection on a large scale forms hurricanes/typhoons. QED
And alarmists worry about radiation.
That is a great graphic! If this planet did not have means of self regulation I don’t think life would be possible. The geological record shows a fairly stable environment, even including the interglacials, for the last 600 million years or so. It is a beautiful and elegant system of self regulation and the more we learn the more we can appreciate it.
Oh nooooooo! From M Mann
Cool.
Of course, it’s important to note that La Nina’s and hurricanes have the exact opposite effect on ocean heat. La Nina’s are a time that the oceans absorb more heat than they release when looked at in totality (hence less is released to the atmosphere), whereas hurricanes are huge engines that suck heat out of the ocean.
‘Tis the season.
Could we be about to see a double-dip La Nina, where the 2nd year is stronger? This Nina is certainly coming on faster than the 2008-2009 2nd year Nina episode. CFS and CFSv2 see -1.5 to -2C, which would put it colder than 2010-2011 La Nina.
Problem: How to get lots of fresh water from the warm tropics to the far North to form huge Continental Galciers in order to counter Anthroprogenic Global Warming?
Hint: Ask a woman. (Irene knows;-)
The question becomes: what is the impact of huricane Irene’s ocean heat loss on subsequent tropical storms this huricane season? Having traveled the East Coast, the ocean heat loss may be made up by infill heat, conduction, as well a Gulf Stream current flow, that as far as ocean heat content is concerned and its potential to feed following huricanes, all is a wash in two weeks time.
I noticed that Tropical Depression Jose seems to have “Petered” out.
So if global warming causes an increase in the number and severity of tropical storms, that will produce a negative feedback by moving the excess heat to higher altitudes, past the CO2 and water vapor that supposedly cause the warming, and by precipitating some of that water vapor back out as rain.
And the assertion that increasing CO2 sets off a POSITIVE feedback loop, creating runaway warming, is demolished.
It’d be worth to compare the above image with an animation found on one of the pages (http://tropic.ssec.wisc.edu/tropic.php) suggested by PearlandAggie on Tropical Cyclone Page, namely:
http://tropic.ssec.wisc.edu/real-time/mimic-tpw/global2/main.html
Please, find the two enormous swirls on the Western part of Pacific Ocean. The Eastern part also shows gigantic swirl. All in all the starting point for all of the moves of the precipitable water masses lie in the middle of Pacific. The two Asian cyclones are supplied with additional energy coming from Indian Ocean as well.
Decidedly animation for Mr Bob Tisdale (http://bobtisdale.blogspot.com/) who is searching for the causes of super La Nina’s energy dissipation. 😉

And with continued comparative Solar magnetic weakness Svensmark’s albedo holding steady, tectonic tension loaded for elastic release.
Like most, I see a real parallel between the hype of Irene and AGW. Journalists and politicians glory in “crisis.” It helps put the spotlight on themselves as being the sages that now pronounce with authority “what is.” Yet the stage is continually littered with these failed prophets of doom. Irene led to the classic syndrome of hype with more hype and drama lavishly laddled up to an adoring public looking for guidance. But most missed the obvious. Even in the aftermath, very few noted that since the storm was from its inception altogether too large and ill-formed to then become “organized” further without significant input from lower and warmer latitudinal waters, and could not possibly hold together any longer than it did. Indeed, there was not a single cautionary note broadcast from the MSM or the Weather Channel that this storm was weakening even before hitting NC, and its disorganization becoming more telling. Instead, true to form, except for the very few, most went hysterically ahead and hoped for the worst, not paying any attention to the possibility of a weakened storm, nor the weakening of their own soapbox.
Blech. Down with la nina. We’ve had it with her antics here.
A few more like that and the warmth of the Gulf Stream to Western Europe will take quite a hit.
During the late 20th century warming period the main hurricane tracks were into the Gulf of Mexico whereas now they seem to favour a track up the Eastern US.
Was it like that during the mid 20th century cooling period ?
Could we use the favoured hurricane tracks as a diagnostic indicator for a warming or a cooling world?
My hypothesis set out elsewhere is that in a warming world the mid latitude jets move poleward and/or become more zonal but in a cooling world they move equatorward and/or become more meridional..
So one could suggest that when the mid latitude jets are more equatorward/meridional they more readily and more often interact with hurricanes to draw them poleward and up into the mid latitude depression tracks. In contrast when the mid latitude jets are more zonal/poleward they fail to draw hurricanes poleward so that hurricanes stay in the tropics more often or for longer.
Interesting that these pattern changes are occurring DESPITE increasing human CO2 emissions.

Wow.
Keep an eye on TD12. It didn’t get the “Jose” name as some had predicted, it will get the “K” name but still looks on track to visit NC outer banks and Delmarva in about 9 days time.

“…who is searching for the causes of super La Nina’s energy dissipation…”
That will be an interesting search since it is super (or regular) El Nino’s that dissipate energy to the atmosphere. La Nina’s are a time the oceans absorb more net energy, not dissipate it.
So…. more La Nina…. what does that mean for TEXAS?????

Very crappy non sequitur Gates. Hurricanes suck heat from the ocean and dump it into outer space. It is not relevant if it occurs during El Nino or La Nina, they are still massive heat extractors. And it is an outright lie to state “it’s important to note that La Nina’s and hurricanes have the exact opposite effect on ocean heat.”, as if to imply during [La Ninas], hurricanes add heat to the ocean. Total nonsense.
Mods, please change my use of “El Ninos” in my last sentence to “La Ninas” Thank you.

I was not the one who mentioned Hurricanes and La Nina together in the same post. And hurricanes do not only “dump” energy to outer space. The move it from ocean to atmosphere and land. Some of will of course dissipate to outer space, but not all of it, or even nearly all of it.
It is important to note that La Nina’s are, in a the bigger picture, doing the exact opposite of hurricanes, as more net energy enters the ocean than leaves during La Nina. In this regards, El Nino’s are far more similar to what hurricanes do.

You’re talking apples and oranges here. Of course they have an “exact opposite effect”. The proper comparison would be the sea state post hurricane: having released all that energy, the oceans will be in a state where they will “absorb more heat than they release”. Similarly, if you truly account for the “totality” of a La Nina event, then you have to account for the processes which led to this depleted energy state.
