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 National Weather Service has declared a heat advisory for Palm Beach County until 6 p.m. today. The advisory, which covers the coast, inland and metro areas of the county as well as Miami-Dade ...
Dimension. Index calculated to be similar to a temperature. Apparent temperature, also known as " feels like ", [1][2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.
Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
As heat indices climb into the 108-112-degree range, there are steps you can take to avoid heat exhaustion and stroke. County offers tips for surviving current heat advisory Skip to main content
As a two-part measurement, heat index can be measured using charts or online calculators to explore the difference between the two figures and the amount of danger that heat index represents. A ...
The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).
