As I summarize in the book: «global warming, which ought to intensify the average hurricane, could also change the regions of storm formation or the numbers of storms that form in the first place.

Anyone here know of an explanation for the formation of hurricanes such as I give in Chapter 4A for eg 2017 & 2010 North Atlantic Hurricanes?

Wind shear is related to the rate at which different layers in the atmosphere move — zero shear means that the layers all move together, large shear means that the upper layers are moving very differently to those below — and is inimical to hurricane formation and intensification.

Q. Is it the differences in temperature or the absolute temperature that encourages hurricane formation?

The perceptible (and perhaps measurable) impact of global warming on hurricanes in today's climate is arguably a pittance (or noise) compared to the reorganization and modulation of hurricane formation locations and preferred tracks / intensification corridors dominated by ENSO (and other natural climate factors).

Hurricanes are likely to become fewer in number, but fiercer in nature according to two recent studies assessing the impact of climate change on hurricane formation.
