Hurricane Regime?

I'm watching a program called Earthshocks on the discovery channel, this particular episode is about hyper hurricanes, fun subject for someone who lives by the ocean in the mid-Atlantic but I digress, they keep using the term 'hurricane regime', seriously, regime??? The dictionary says a regime is a system of government, that's what I thought it meant, I looked it up incase I was mistaken, so how can they call a hurricane a regime??
