Residents in the southeast are getting familiar with how extreme wind chills of -40 feel, but they may be wondering just what wind chill is and how it's calculated.
Meteorologist with Environment Canada Dan Kulach explained during an interview with Discover Weyburn that windchill is a calculation based on the temperature and the wind speed.
"Cars and objects like that sitting outside, they can only get as cold as the air temperature," explained Kulach. "Even if the wind is just howling out there and you got a bitterly cold wind chill it's because, again, temperature and wind chill are not the same and if a strong wind did affect the temperature, a thermometer would obviously never be able to work in a wind."
Kulach said the equations that go into the wind chill index attempt to simulate what the wind feels like on a person's bare face.
