I can see how a reduced polar-equatorial temperature gradient might
reduce the number or intensity of mid-latitude depressions, but I can't
see how it could have an effect on hurricanes. But then my knowledge of
atmospheric dynamics isn't very good.


Better than mine. I am at the very bottom of the pile for anything on-
topic in this particular ng.

I always understood the mechanism as being a reduction in the capability
of systems (tropical waves) to organise themselves, rather than any
effect on a system once it had become tropical.
