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).

The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
Apparent temperature, also known as "feels like", [1] [2] ... the WBGT is linked to a category system to estimate the threat of heat-related illness. ...
Per NCHSAA guidelines, “A wet bulb globe temperature (WBGT) chart should be available at practices and contests. If an instrument to assess WBGT is unavailable, the heat and humidity guidelines ...
The highest recorded temperature in the U.S. was also recorded in California's aptly named Furnace Creek in 1913. It was 134 degrees on July 10. peterleabo/istockphoto.
The new policy was invoked on January 20, 2003 on a day when the temperature reached 37 °C (99 °F) and the WBGT reached the 28 °C (82 °F) mark. [8] Play was halted for the minimum 2 hours. After the extreme heat policy was invoked in consecutive years in 2006 and 2007, the policy was again changed starting in 2008 to allow matches in ...
An intense blast of cold air has taken up shop in the central United States this week with temperatures up to 50 degrees below average and over 200 daily cold records at risk of being broken.
A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
