Dew point temperature is also used to indicate how much moisture content, dew point temperature is higher, it means more water vapor content of the air. Heat Index: heat index of real human body temperature at a high temperature and humid environment feel. When the body is in a high temperature environment, the body will automatically adjust the body can achieve more comfortable temperature, one of the mechanisms of body heat is sweating, the sweat evaporation process consumes energy, so the purpose is to promote sweating evaporated, then consumes our body heat. We are cool. When the temperature is high and low humidity, the body will soon be discharged from the sweat evaporate; on the contrary, at high temperature and humidity is also high, people go back to slow down the rate of evaporation of sweat a lot, when the temperature is due to the humidity up or in the case of long-term human sweat can not evaporate, then there will be cramps, heat exhaustion and even heat stroke happen. This index can only be used as reference, this is because different people different degree of adaptation to heat. Changes in the situation of human heat index 32.6 ℃ ~ 40.4 ℃ careful - there may be cramps and heat exhaustion 40.7 ℃ ~ 54.2 ℃ danger - possible human failure and 56.5 ℃ ~ 78.2 ℃ very dangerous - at any time heatstroke cold Index: cold and wind weather big time, the heat generated by the human body will quickly taken away by the wind, feel the temperature of the body and therefore lower than the actual temperature. This is the feeling of cold temperature indices. Wind chill index will be affected by the temperature and wind speed, wind chill index case is low, should avoid prolonged exposure to the outdoors, so as to avoid excessive loss of body heat and dangerous. UV Index: The UV index is a measure of the extent of the earth's surface solar ultraviolet radiation affect human skin. UV Index UVI trace levels 0-2 3-4 5-6 in a low level middleweight 7-9 excess risk of grade level 10 to 15 Origin: China
