Apparent temperature is the general term for the perceived outdoor temperature, caused by the combined effects of air temperature, relative humidity and wind speed. *The heat index and humidex measure the effect of humidity on the perception of temperature. In humid conditions, the air feels hotter than it actually is, because of the reduction in evaporation of perspiration. *The wind chill factor measures the effect of wind speed on cooling of the human body below 50 F (10 degrees C) . As airflow increases over the skin, more heat will be removed. Standard models and conditions are used. *The Wet Bulb Globe Temperature (WBGT) combines the effects of radiation, humidity, temperature and wind speed on the perception of temperature. It is not often used as the resulting figure is very location specific (e.g.: cloud cover and/or wind shielding). ==See also== * Equivalent temperature 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「apparent temperature」の詳細全文を読む スポンサード リンク
