Strong winds in Kansas played a large role in creating the bitterly cold temperatures this week that sent the wind chill plummeting.
Wind chill is the rate of heat loss on the human body resulting from the combined effect of low temperature and wind. In other words, it feels colder if the wind is blowing.
So how is wind chill calculated? Considering the weather this week...that's a good question. The air temperature is one thing. Factor in a twenty mile per hour wind, and it can feel like Siberia.
But exactly how is wind chill calculated? Meteorologist Jay Prater says the formula for factoring windchill is:
35.74 + 0.6215T - 35.75 (VO 016) + 0.4275T + (VO.16)
If you're not a meteorologist the National Weather Service has a windchill chart that can make figuring it out a lot easier. The chart also lets you know how long it takes in bitter temperatures to get frostbite.
