“Wind Chill Factor” and “Heat Index”

Okay, the meteorologists often say, “…making it feel like xx degrees.” Who exactly does it feel that temperature to? I thought applied science, which meteorology claims to be, was usually based on standards.

So, does The National Bureau of Standards (USA) have a guy, let’s call him Joe, locked in a room in Boulder, Colorado, and the wind or heated temperature feels like xx degrees to Joe? If so, shouldn’t it be called the Joe Wind Chill Factor and the Joe Heat Index? … Otherwise…

Well, this is just another of my many pet peeves.
