, bomb cyclogenesis is the formation of an over-land cyclone ("cyclogenesis") in a dramatically short period of time ("kablooey").

This kind of extreme drop in pressure is referred to as "explosive cyclogenesis" or "bombogenesis"

I wonder then if the fact that it was warmer at the northern latitudes was a factor in TC cyclogenesis this year.

It is shown that a large part of the variability of overall “hurricane activity” — which depends on the number of storms in a season, their duration, and their intensity — can be explained by systematic shifts in the cyclogenesis regions.

It is a pretty good bet, barring a hemisphere-wide rash of tropical cyclogenesis, that the period from June 1 – November 30, 2007 in the Northern Hemisphere will be the quietest TC season (in terms of ACE) since 1977 (also June-Nov).

A change of at least 5-10 m/s in wind shear would probably be needed for a significant change in tropical cyclogenesis.
