Climate and Weather


Is there a formula for computing the wind chill?

Here is how you calculate the New Wind Chill Index:

      Twc 5 35.74 1 0.6215T – 35.75(V0.16) 1 0.4275T(V0.16)

Twc is the wind chill in degrees F, V is the wind speed in miles per hour, and T is the temperature in degrees F.
