The westerlies, anti-trades, [2] or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes (about 30 degrees) and trend towards the poles and steer extratropical cyclones in this general manner. [ 3 ]
Prevailing winds are strongly influenced by Earth's overall atmospheric circulation, in addition to smaller-scale and shorter-lived weather phenomena. In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind ...

The habagat season is characterized by hot and humid weather, frequent heavy rainfall, and a prevailing wind from the western parts. The main indicator of the switch between the amihan and habagat seasonal patterns is the switch in wind direction. In most years this transition is abrupt and occurs overnight.
A monsoon is a seasonal prevailing wind that lasts for several months within tropical regions.

A type of weather warning formerly issued by the U.S. National Weather Service to alert areas in which a high rate of snowfall (generally 6 in (15 cm) or more in 12 hours) was occurring or was forecast. The warning was replaced by the Winter Storm Warning for Heavy Snow beginning with the 2008–09 winter storm season. helicity high-pressure area

Prevailing visibility in aviation is a measurement of the greatest distance visible throughout at least half of the horizon, not necessarily continuously. To take the prevailing visibility, controllers reference a number of visual reference points: usually buildings , hills , or other geographic features.
