wind chill

The cooling effect of wind at low temperatures. This is greater than the effect of ambient cold alone and may cause rapid heat loss, adding to the risk of HYPOTHERMIA.

wind chill

because strong winds magnify convective heat loss from the body, a climatic hazard is not exposed simply by quoting the temperature. A combination of air temperature and mean wind speed gives the important wind chill index.

wind chill index
derived from the equation:$$\hbox{W}_{\rm CI}=(10\times \hbox{W}^{-2}+10.45-\hbox{W})(33-\hbox{T})$$
where WCI = wind chill index; W = mean wind speed in meters/sec; T = air temperature in degrees Celsius.
wind chill temperature
special thermometers are available to express the effect of wind on the sensation of temperature. Based on the estimation of what the air temperature feels like to a human when the particular temperature is accompanied by a wind of a certain speed.
