While temperatures plummet, the actual air can feel much colder than what the thermometer reads when factoring in the wind. Let’s take a look at the science of wind chill. Wind chill occurs when cold air and wind are both present. The wind removes a layer of heat that surrounds the body by blowing cold air across exposed skin. While the heat is removed from the outside of the body, the inner temperature can also begin to drop. If exposed long enough to cold wind chill values, hypothermia and frostbite can occur and result in discomfort, illness and even death. The wind chill values decrease exponentially with colder temperatures and stronger winds. For example, when the temperature is 40 degrees outside with a wind speed of 30 mph, the wind chill value is 28 degrees. However, for the same wind speed with a temperature of 10 degrees, the wind chill value is a frigid 12 degrees below zero. It’s important to pay attention to the wind chill as body heat is removed faster with colder values. When the wind chill value is 15 degrees below zero or colder, frostbite occurs in little as 30 minutes while for values of 32 degrees below zero or colder, frostbite can occur in 10 minutes. There’s no wind chill when temperatures are above 50 degrees as the layer of heat surrounding the body is hard to remove with such mild air. This winter season it is important to look out for Wind Chill Warnings and Advisories which signal particularly dangerous cold that elevates the risk for frostbite and hypothermia. _Source:_ weather.gov \---------- _Story Image_ via pixabay.com We use technologies, such as cookies, to analyze your use (i.e., pages visited), to customize content, for our internal analytics purposes and for security and other purposes.
