The strongest westerly winds in the middle latitudes can come in the roaring forties, between 40 and 50 degrees south latitude. The westerlies play an important role in carrying the warm, equatorial waters and winds to the western coasts of continents, especially in the southern hemisphere because of its vast oceanic expanse.
Foehn winds usually occur when the westerly wind belt moves northwards. [7]The foehn effect on the coastal plains of southeastern Australia is mostly linked with the passage of a deep low pressure system or westerly cold fronts across the Great Australian Bight and southeastern Australia that cause strong winds to reorient virtually perpendicular to some parts of the Great Dividing Range ...
The Roaring Forties are strong westerly winds that occur in the Southern Hemisphere, generally between the latitudes of 40° and 50° south. [2] The strong eastward air currents are caused by the combination of air being displaced from the Equator towards the South Pole , Earth's rotation , and the scarcity of landmasses to serve as windbreaks ...
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.
The Southern Annular Mode is usually defined as the difference in the zonal mean sea level pressure at 40°S (mid-latitudes) and 65°S (Antarctica). [1]The Antarctic oscillation (AAO, to distinguish it from the Arctic oscillation or AO), also known as the Southern Annular Mode (SAM), is a low-frequency mode of atmospheric variability of the southern hemisphere that is defined as a belt of ...
It is characterized by the north–south displacement of the westerly wind belt that circle around Antarctica. [43] Such variation in the position of the westerly wind belt affects the intensity and position of cold fronts and mid latitude storm systems and is partly responsible for variation in precipitation in the southern parts of Argentina.
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 dried air then descends on the leeward side of the mountains, warming at the dry adiabatic rate of 10 °C / 1000 m (5.5 °F / 1000 ft). [14] The turbulence of the high winds also can prevent the usual nocturnal temperature inversion from forming on the lee side of the slope, allowing night-time temperatures to remain elevated. [14]
