The trade winds or easterlies are permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere , strengthening during the winter and when the Arctic oscillation is in its warm phase.
The westerlies (blue) and trade winds (yellow and brown) The general atmospheric circulation. Trade winds (red), westerlies (white) and the South Pacific anticyclone (blue) [1] 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.
The trade winds (also called trades) are the prevailing pattern of easterly surface winds found in the tropics near the Earth's equator, [4] equatorward of the subtropical ridge. These winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere . [ 5 ]
The trade winds act as the steering flow for tropical cyclones that form over the world's oceans. [32] Trade winds also steer African dust westward across the Atlantic Ocean into the Caribbean, as well as portions of southeast North America. [33] A monsoon is a seasonal prevailing wind that lasts for several months within tropical regions.
Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in China and Taiwan as meiyu (梅雨), in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
George Hadley (12 February 1685 – 28 June 1768) was an English lawyer and amateur meteorologist who proposed the atmospheric mechanism by which the trade winds are sustained, which is now named in his honour as Hadley circulation. As a key factor in ensuring that European sailing vessels reached North American shores, understanding the trade ...
In the Northern Hemisphere, trade winds blow from northeast to southwest, from North and South America toward Asia, between the equator and 30 degrees north latitude. Typically, the trade winds continue across the Pacific, unless something gets in their way, like an island. Hawaiʻi's high mountains present a substantial obstacle to the trade ...
Immanuel Kant, also unsatisfied with Halley's explanation for the trade winds, published an explanation for the trade winds and westerlies in 1756 with similar reasoning as Hadley. [82] In the latter part of the 18th century, Pierre-Simon Laplace developed a set of equations establishing a direct influence of Earth's rotation on wind direction ...
