This calculator estimates heat index temperature felt by the human body based on the actual measured air temperature together with humidity level or dew point.
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 ...
12 Μαΐ 2022 · The Heat Index Equation. The computation of the heat index is a refinement of a result obtained by multiple regression analysis carried out by Lans P. Rothfusz and described in a 1990 National Weather Service (NWS) Technical Attachment (SR 90-23). The regression equation of Rothfusz is.
Calculate the heat index based on air temperature and relative humidity using a simple formula and a chart. Learn how to use this calculator and what factors affect the heat index.
Heat Index. by Tim Brice and Todd Hall. Enter a temperature that you would like and choose your units: What the temperature feels like to your body: Fahrenheit Celsius. ° F. Enter your relative humidity: %.
The equation for HI above with the appropriate adjustment is used to compute a maximum heat index using the forecast maximum temperature and an estimated 00 UTC dew point temperature at each forecast point location for each forecast projection day.
