Felt air temperature
Felt air temperature (or apparent air temperature) is a quantitative measure that indicates the amount of heat the human body loses outdoors in a given time and place.
It is an indication of the air temperature perceived by the body, which may differ from the actual temperature due to other climatic conditions affecting the exchange of heat between the body and the air.
The factors contributing to the felt air temperature are air humidity, density, and the speed of wind at five feet (1.5m) from the ground where the average human face is.[1] The ability of the air to absorb heat is affected by its relative humidity, and its density. The faster air blows over a surface, the more air is brought into contact with that surface in a given time interval, increasing the heat loss or gain of the body. This is reflected in the wind chill referring to the reduction of felt air temperature resulting from the wind.
Feels like is a meteorological expression used in weather forecasting and weather reports referring to the felt air temperature.
