In European tradition, it has usually been considered the mildest and most favorable of the directional winds. In ancient Greek mythology and religion, the god Zephyrus was the personification of the west wind and the bringer of light spring and early summer breezes; his Roman equivalent was Favonius (hence the adjective favonian, pertaining to the west wind).
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.
'westerly wind'), also spelled in English as Zephyr, is the god and personification of the West wind, one of the several wind gods, the Anemoi. The son of Eos, the goddess of the dawn, and Astraeus, Zephyrus is the most gentle and favourable of the winds, and is also associated with flowers, springtime and even procreation. [1]
Like trade winds and unlike the westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. [15] Due to the low sun angle, cold air builds up and subsides at the pole creating surface high-pressure areas, forcing an outflow of air toward the equator ; [ 16 ] that outflow is deflected westward by the ...
The convention for directions refer to where the wind comes from; therefore, a 'western' or 'westerly' wind blows from the west to the east, a 'northern' wind blows south, and so on. This is sometimes counter-intuitive. Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls.
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 winds that flow to the west (from the east, easterly wind) at the ground level in the Hadley cell are called the trade winds. Though the Hadley cell is described as located at the equator, it shifts northerly (to higher latitudes) in June and July and southerly (toward lower latitudes) in December and January, as a result of the Sun's ...
The North Equatorial Current (NEC) is a westward wind-driven current mostly located near the equator, but the location varies from different oceans. The NEC in the Pacific and the Atlantic is about 5°-20°N, while the NEC in the Indian Ocean is very close to the equator.
