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 term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". [2] The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.

Temperature differences also drive a set of circulation cells, whose axes of circulation are longitudinally oriented. This atmospheric motion is known as zonal overturning circulation . Latitudinal circulation is a result of the highest solar radiation per unit area (solar intensity) falling on the tropics.
The westerlies and trade winds Winds are part of Earth's atmospheric circulation. ... When the temperature onshore cools below the temperature offshore, the pressure ...
Westerly winds blowing across the Atlantic bring moist air into Europe. In years when westerlies are strong, summers are cool, winters are mild and rain is frequent. If westerlies are suppressed, the temperature is more extreme in summer and winter leading to heat waves, deep freezes and reduced rainfall. [7] [8]
The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong [ 1 ] and Fiji, [ 2 ] it is represented by a bold line extended from a low pressure center [ 3 ] or between two low pressure centers; [ 4 ] in Macau [ 5 ] and Australia, [ 6 ...
