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.
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).

‘Wet-bulb temperature’ refers to temperatures taken with a thermometer covered in a wet cloth, which are normally slightly cooler than ‘dry-bulb’ temperatures. ...
An art movement is a tendency or style in art with a specific art philosophy or goal, followed by a group of artists during a specific period of time, (usually a few months, years or decades) or, at least, with the heyday of the movement defined within a number of years.
Wet bulb globe temperature is a better indicator of the risk posed by outdoor conditions than either heat index or temperature, experts say.
As the planet continues to get hotter, humans are at greater risk for heat-related illness and death but an index aims to avoid such.
Some of these movements (such as Dada and Beat) were defined by the members themselves, while other terms (for example, the metaphysical poets) emerged decades or centuries after the periods in question. Further, some movements are well defined and distinct, while others, like expressionism, are nebulous and overlap with other definitions.
See Art periods for a chronological list. This is a list of art movements in alphabetical order. These terms, helpful for curricula or anthologies, evolved over time to group artists who are often loosely related. Some of these movements were defined by the members themselves, while other terms emerged decades or centuries after the periods in ...
