Wind chill chart 60 degrees4/29/2024 ![]() ![]() While the wind doesn’t actually alter the true air temperature, to your hands, which are already losing heat to the cold winter air, the blowing winds make the surrounding air feel even colder since heat is transferred even faster as the wind moves the air over your exposed skin at a faster rate. So now, you have the wind moving over your hands which pulls heat away faster than just the conductive heat loss to the calm, already cold air. You now have your hands losing heat to the colder surrounding air, coupled with winds blowing over your exposed hands. The heat from your hands which are much warmer than the air, being transferred to the colder, lower temperature air. Your hands gradually get colder and colder. If there’s no wind, you feel that air at the actual air temperature. As you step outside, any exposed skin comes into direct contact with the surrounding air. heat from the sun microwave oven heating up food)īased on this theory, as air temperature decreases and wind speed increases, exposed skin loses heat faster and the air feels colder on the skin through conduction/convection. Radiation: Emission of electromagnetic rays, does not require a medium like water (ex.boiling water, clouds/thunderstorms (hot air rises/cold air sinks & creates instability)) Convection: Heat transfer via movement of fluid like air or water (Ex. ![]() hot coffee poured into a mug heats the mug up) Conduction: Heat transfer by touch slowest of all heating methods (Ex.It also incorporates heat transfer theory, which essentially says heat can be transferred due to a temperature difference, always from higher temperature to lower temperature, via three methods: No impact from sun (think a clear night sky).Wind readings at standard height of anemometer: 33 feet.Fortunately, we have made this easy for you- see below for an easily digestible motorcycle wind chill chart that breaks down wind chill. Average height: 5 feet (typical height of human face) Here’s some math for you to do if that’s your thing: Wind chill 35.74 + (0.6215 × T) (35.75 × Wind sfc 0.16 ) + (0.4275 × T × Wind sfc 0.16 ) Wind sfc equals the wind speed and T, the temperature.
