Wind chill is the perceived decrease in air temperature felt by the body on exposed sin due to the flow of cold air. Wind chill temperatures are always lower than air temperature. The human body loses heat through convection‚ evaporation‚ conduction and radiation. The rate of heat loss by a surface through convection depends on the wind speed above that surface. As a surface heats the air around it‚ an insulating boundary layer of warm air forms agains the surface. Moving
