As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat
The Heat Index is a function of temperature and relative humidity. The combination of the two results in an apparent temperature which gives an idea of what it would feel like under normal-to-low
Heat Index = * Please note: The Heat Index calculation may produce meaningless results for temperatures and dew points outside of the range depicted on the Heat Index Chart linked below. Heat Index Chart and Explanation 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. The equation used by the NWS to estimate heat index was developed by George Winterling in 1978, and is meant to be valid for temperatures of 80°F or higher, and relative humidity of 40% or more. Below is a chart based on the NWS equation that can be used to estimate temperature and the level of danger associated with varying relative humidity percentages. A detailed view of the world stock markets that are trading higher or lower with our heat maps of indices from around the globe. index system. The heat index combines both air temperature and relative humidity into a single value that indicates the apparent temperature in degrees Fahrenheit, or how hot the weather will feel. The higher the heat index, the hotter the weather will feel, and the greater the risk that outdoor workers will experience heat-related illness.

The heat index (HI) or humiture 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. Download the NWS heat index chart. Print it in color or open it in a new Internet tab. Put your finger on the air temperature in the column on the far left. Next, run your finger across until you reach your relative humidity (rounded to the nearest 5%) by following the numbers across the top row of the chart. The 'Heat Index' is a measure of how hot the weather 'feels' to the body. The heat index (HI) or apparent temperature or humiture or humidex is an index that combines air temperature and relative humidity. This Heat Index chart uses relative humidity and air temperature in fahrenheit to produce the 'apparent temperature'. A detailed view of the world stock markets that are trading higher or lower with our heat maps of indices from around the globe. The Heat Index is a function of temperature and relative humidity.
