21 Ιουλ 2016 · Calculate the heat index from the temperature and humidity (either relative humidity or dew point), or use a simple heat-index conversion chart.
Heat index chart. In order to determine the heat index using the chart above, you need to know the air temperature and the relative humidity. For example, if the air temperature is 100 ° F and the relative humidity is 55%, the heat index will be 124 ° F.
Exposure to full sunshine can increase heat index values by up to 15°F (8°C). Also, strong winds, particularly with very hot, dry air, can be extremely hazardous as the wind adds heat to the body. The Heat Index Chart is below.
The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade. For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F ...
The ‘Heat Index’ is a measure of how hot weather "feels" to the body. This table uses relative humidity and air temperature to produce the "apparent temperature" or the temperature the body "feels".
heat index °f (°c) The heat index is an accurate measure of how hot it really feels when the affects of humidity are added to high temperature. RELATIVE HUMIDITY (%)
