A consequence of the Coriolis effect, Ekman theory explains that oceanic flow at the surface is directed at 45 degrees to the right of the wind stress in the Northern Hemisphere. Thus, winds blowing from the southwest result in eastward currents, while winds blowing from the northeast result in westward currents.
The path of the Loo (orange arrows) from the deserts of the Indian subcontinent towards and through the Indo-Gangetic Plain of India and Pakistan. The Loo is a strong, dusty, gusty, hot and dry summer wind from the west which blows over the Indo-Gangetic Plain region of North India and Pakistan. [1] It is especially strong in the months of May ...
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 with the highest speed over a particular point on the Earth's surface at any given time.
Consequently, a wind blowing from the north has a wind direction referred to as 0° (360°); a wind blowing from the east has a wind direction referred to as 90°, etc. Weather forecasts typically give the direction of the wind along with its speed, for example a "northerly wind at 15 km/h" is a wind blowing from the north at a speed of 15 km/h ...
Wind direction is usually expressed in terms of the direction from which it originates. For example, a northerly wind blows from the north to the south. [8] Weather vanes pivot to indicate the direction of the wind. [9] At airports, windsocks indicate wind direction, and can also be used to estimate wind speed by the angle of hang. [10]
Monsoons typically occur in tropical areas. One area that monsoons impact greatly is India. In India monsoons create an entire season in which the winds reverse completely. The rainfall is a result of the convergence of wind flow from the Bay of Bengal and reverse winds from the South China Sea. [13]
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.
The Tropical Easterly Jet is the meteorological term referring to an upper level easterly wind that starts in late June and continues until early September. This strong flow of air that develops in the upper atmosphere during the Asian monsoon is centred on 15°N, 50-80°E and extends from South-East Asia to Africa.
