Wind Chill
The Wind Chill is defined as the air temperature of an equivalent environment that, under calm wind conditions, would entail the same skin surface heat loss to the environment as in the actual, windy, environment. It takes into account the assumptions of convective and radiative heat loss described in modern heat transfer theory, and assumes no impact from the sun.

How To Use
You will need 2m air temperature in Kelvin and 10 m wind speed in meters per second.
It returns the wind chill in Kelvin.
calculate_wind_chill(2m_temperature, 10m_wind_speed)
Interpret the Output
The wind chill is described in terms of the risk incurred by human skin, based on the rate of heat loss caused by exposure to wind and low temperatures.
