5. SST anomalies are always colder after a cyclone
at least that's been my observation over the 8 years that I've been watching SST anomalies. This cyclone hovered over the Indian ocean for days before making landfall. Couple that with the enormous amounts of freshening by the huge rain amounts and voila, SSTs cool rapidly.
I saw it after Hurricane Katrina in the GOM and the Bangledesh cyclone that killed so many (SSTs really cooled rapidly after that cyclone), and it's often visible even after flood events.

For some darned reason, I can't access my global SST anomaly site to compare but if you can, do go back to about April 24th on to see if this is correct.

Also, re; tornadoes and and their relation to global climate change comes this from a study done last year by NASA:

Climate models have long predicted that severe storms and other extreme weather will become more frequent and intense as global warming pumps more energy into the atmosphere.

But scientists have shied away about making predictions about the smaller weather events, like tornadoes and thunderstorms, because local weather conditions are so variable and hard to tie to larger climate trends.

No more is that the case, as a new NASA study shows, according to an AP story today. One consequence of a warmer climate is a greater chance of updrafts, the precursor to thunderstorms and tornadoes, according to the NASA research. More updrafts + more heat energy = more intense and frequent storms.

Last night, fyi, the weather channel had graphs to show that there are nearly twice as many tornadoes this year so far as the 10 year average! Naturally, one year does not a trend make but it bears watching.

Sorry for being so wordy but I'm a weather geek so I should probably use the "weather forum" for this stuff. Still, it's a welcome relief to talk of weather and not politics for a change.
