Sure makes a difference when heating a home, that's for sure. I think it's easier to heat a house when it's 20 below with no wind chill effect then it's equivalent of 5 above with a 30 MPH wind. Feels that way, too!
My furnace is running overtime...You’re right...that wind does make a huge difference. I just boiled a pot of water for half an hour to raise the humidity...45% is nice. Makes my apartment much more comfortable.
Engineers call that “forced convective heat transfer.”
Air currents do carry away a lot more heat that areas with quiet air. Quiet air is called “natural convection” and the heat transfer coefficients are a lot lower.
