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.
‘Wet-bulb temperature’ refers to temperatures taken with a thermometer covered in a wet cloth, which are normally slightly cooler than ‘dry-bulb’ temperatures.
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).

A wet-bulb measurement is taken by covering a thermometer with a water-soaked cloth. The process of the water evaporating from the cloth, thus lowering the temperature, mirrors how the human body ...
Wet bulb globe temperature is a better indicator of the risk posed by outdoor conditions than either heat index or temperature, experts say.
Artists may choose to "correct" perspective distortions, for example by drawing all spheres as perfect circles, or by drawing figures as if centered on the direction of view. In practice, unless the viewer observes the image from an extreme angle, like standing far to the side of a painting, the perspective normally looks more or less correct.
Wet-bulb potential temperature, sometimes referred to as pseudo wet-bulb potential temperature, is the temperature that a parcel of air at any level would have if, starting at the wet-bulb temperature, it were brought at the saturated adiabatic lapse rate to the standard pressure of 1,000 mbar.
What wet bulb globe temperature tells you about the weather In hot temperatures, the human body typically creates sweat as a way to control body temperature through evaporative cooling.
