Why bother? Studies like that cost money, and the results wouldn't change anything. And if some industry wanted to know (like insurance companies), they would want the taxpayers to pay for it.

People still wouldn't build tornado shelters, they wouldn't move out of the flood plain, they wouldn't stop building on the sides of hills, they wouldn't evacuate out of the path of a firestorm. They go skiing/snowboarding in avalanche conditions, head into a blizzard with no preps or suitable clothing, go jogging at noon in heat waves, and hurry down to the beach to watch the incoming tsunami.

Things like air accidents are relatively confined, weather-related deaths aren't; did this person die from the tornado because he was caught out in the open? Was he brained by a 2x4 going 200 mph that came through his bedroom wall? Was he out in the front yard getting a video of the storm?

And how on earth would you factor in the Darwin Award nominees???
