I certainly get the "adrenaline rush" part, but as has been pointed out:
a) the guys on TV are professional meteorologists collecting data for scientific research and,
b) those guys are on TV.
Although the show is definitely not fiction, it is for entertainment! This may be a, "Well, duh!" statement, but the program is edited for (hopefully) maximum interest value. If you were really to follow a professional storm chaser, you would probably be bored to tears. It can be long hours of driving around for days or weeks on end and seeing absolutely nothing! That may be OK for Nova, but not for The Discovery Channel that relies on advertising revenue.

My wife thinks I am crazy (but that's a topic for another forum!), but I will admit that one thing I want to do is go on a chase at least once before I die. If you Google "storm chasing tours" you will see LOTS of choices. I am still checking some of them out and haven't narrowed down any of my choices yet. At least I know I will be going with professionals who are (supposedly) intimately familiar with severe weather and will have my personal safety at the top of their list.
