Makes sense - it's friggin' cold here like 4-5 months out of the year. The part that really blew my mind is that it only dates back to 2001. I was almost an adult then, and I don't ever remember it not being a thing.
Windchill wasn't invented in 2001, just the new international standard.
I do seem to remember the effect from before 2001. But why was it invented? I mean sometimes it's kinda cool, but others it can be downright deadly. ;-)
I remember am radio reporting windchills like this, when I was a child. "Today's high is -26C with a windchill of 2200. This means frostbite in three minutes on exposed skin, so bundle up!" And my parents had a chart that converted windchill values to frostbite times.
Going further back, I remember when that watts per square metre (the 2200 in your weather report) was introduced as a replacement for whatever windchill calculations they were using before.
One thing many people I know get wrong about windchill is the effect on needing to plug in a vehicle's block heater. If you normally are good down to -20C on a calm day, you'll also be good down to -20C on a windy day, despite windchill being far below -20. The engine will cool faster, not farther.
No matter how fast the engine cools off, it still won't get any colder than the actual air temperature. Of course, that also means that if you are good for 4 hours at -20C on a calm day, starting with a hot engine, then adding wind means you might only be good for 2-3 hours.
I think they are meaning 2001 was when it was standardized internationally by Canada's work on it. We definitely had windchill warnings when i was a kid in 80s and 90s, but not based on a standard measuring system
Okay, thanks for that. I thought I was losing my mind.
