Wind Chill. I do not think it refers to living tissue. I think the
definition is how much heat transfer would occur in still air vs. Moving
air. some low speed of air. -15 degrees with a wind chill of -30, says
the same heat loss would occur if the temp was -30 and no wind movement.
Nothing to do with evaporation but with the tendency of the air to heat
up near the warmer object, slowing down heat transfer.


The term "Wind Chill" applies *only* to living tissue. It refers to the
rate of cooling (limited by the ambient temperature) that occurs to
exposed living tissue. The increased rate of cooling can exceed the
living tissue's ability to replace the heat lost and things like frostbite
can quickly occur.

The wind can't make it colder. It only makes the rate of heat transfer
and cooling of the object faster. Heat transfer is higher in turbulent
flow.

Did not realize it applied only to human tissue. Thought it was just a rate
of heat transfer regards air movement.
