As explained by MIT physicist Richard Lindzen, the reduction of the temperature differential between the north hemisphere and the equatorial part of our planet makes
cyclonic energy much smaller: the importance and frequency of extreme events thus tend to decrease.
Via the Weather Underground, here is Accumulated
Cyclonic Energy for the Western Pacific (lower numbers represent fewer cyclonic storms with less total strength):
Over that same 17 years there is no obvious trend in the total
cyclonic energy index, droughts, floods, or tornadoes.
He named this the Accumulated
Cyclonic Energy.

And shear is important in generating «eddies» —
cyclonic or anticyclonic swirls of
energy — within the overall wind flow.
(If this is true then the deeper
energy content should be much lower and hence a poor source for feeding a
cyclonic phenomena.)

I doubt that the
energy - transporting effects of thunderclouds, summer squalls,
cyclonic storms, monsoon rains, etc. are known with quantitative precision.even approaching 10 % Are they?
It's far from a complete picture of the
cyclonic processes because one has to take into account that there are changes in
energy due to altitude and that the system is open; able to draw in e.g. less - humid air from around the storm, leading to further surface evaporation.
A better metric is the total
energy of
cyclonic storms, land - falling or not, where again there is no trend.
