LOL. This from a scientist? Ya, I guess if its raining alot in Austin, Tx. there cant possibly be a drought going on.
You guys ready for the season? Cause its getting ready for you...

Now, dont get to gitty, but its about to rain again in Austin Tx in about 90 min....

So why dont you take some of your water bill saving and apply it to the BB&B ATAC fund. Your shitin in high cotton Mr Scientist...

This is not an easy test. There are far too many factors that affect hurricane creation and strength that would be ommitted from the equation. As we have seen with hurricane coverage on the news, it only takes a little wave of energy to alter the stregth of a hurricane. I do agree that it would appear to give you an idea of a corrolation, but there is too much variability between each of the storms for them to be compared to each other.
Always remember, any good statistician can make the numbers say exactly what he/she wants them to.

that's really my point. if the correlation is as temperature-dependant as salty says, it should show up in a simple experiment like that.

Here is a link to an article that shows some correlation.
http://www.livescience.com/environme...urricanes.html
"As a hurricane builds up energy, it feeds off heat from the water. As water heats up, it turns into water vapor. As water vapor rises, it cools, condenses into rain, and releases heat that fuels the hurricane. The higher the vapor rises, the more heat is released, and the more intense the storm."

Bump for Salty. In this case, the Nature article is better evidenced than your livescience piece.

Doesn't refute the physical reality that higher sea temperatures lead to more intense hurricanes.

I don't think you actually read the Nature article. The CNN synopsis is at best an abstract.

randerizer, here is a newer article (june 7...Nature) that contends that intense hurricanes are due to wind-shear associated with El Ninos. In that regard it contradicts the May 24 article in Nature.
Note that the June 7 article places the key formational factors for intense hurricanes on wind-shear and sea temperatures.
http://www.sciencenews.org/articles/20070609/fob8.asp
It would seem to me that if one had higher sea temperatures and wind shear, more intense hurricanes will form, at least occasionally.

The writers at Nature do not think so. Instead, they posit in an introductory piece to the newer article that, taken together, the 2 works suggest that there are significantly more factors in hurricane activity than just temperature, as has been previously considered primary.

They find a relation to wind-shear, but the article actually disputes a direct link to SST.

Like ULM winning a football game? :D
From the June 7 article:
Furthermore, the current active phase (1995–2005) is unexceptional
compared to the other high-activity periods of
,1756–1774, 1780–
1785, 1801–1812, 1840–1850, 1873–1890 and 1928–1933 (Fig. 3),
and appears to represent a recovery to normal hurricane activity,
despite the increase in SST.
Wavelet spectral analyses together with spectral analyses reveal the
existence of significant
,8–11 and,20–30-year cycles in the records
(see Supplementary Information). Decadal signals in occurrences,
formation areas, and landfalls of tropical storms and hurricanes have
also been identified elsewhere and linked to the North Atlantic
Oscillation
