What Is The Heat Index Youtube Learn all about the heat index in this short video from duane friend, an environmental and energy stewardship educator with university of illinois extension. The heat index is a weather term used by meteorologists almost daily. what does it mean? how does it relate to feels like temperatures? the national weather.
What Is The Heat Index Youtube The heat index, also known as the apparent temperature or “feels like” temperature, is a measure that combines the actual air temperature and relative humidi. The heat index explained 01:20. next up. watch this huge dust devil up close in washington 00:24. horses run from wildfire burning near reno, nevada 00:32. thousands flee as california line fire. In simplest terms, the heat index is the "feels like" temperature, or how hot it really feels when the relative humidity is factored in with the actual air temperature. the heat index is forecast. This is the reason the heat index chart was developed. the heat index is based on work by r.g. steadman and published in 1979 under the title “the assessment of sultriness, parts 1 and 2.” in this work, steadman constructed a table which uses relative humidity and dry bulb temperature to produce the “apparent temperature” or the temperature the body “feels”.

Figure 1. 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. when the relative humidity is low, the apparent temperature can actually be lower. 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.
