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 dominant winds are the trends in direction of wind ...
Harmattan, a dry wind that blows from the northeast, bringing dust from the Sahara south toward the Gulf of Guinea. Khamsin (khamaseen in Egypt) and similar winds named Haboob in the Sudan, Aajej in southern Morocco, Ghibli in Libya and Tunisia, Harmattan in the western Maghreb, Sirocco, a south wind from the Sahara and Simoom in the Arabian ...
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. They originate from the high-pressure areas in the horse latitudes (about 30 degrees) and trend towards the poles and steer extratropical cyclones in this general manner. [ 3 ]
Chinook winds, or simply Chinooks, are two types of prevailing warm, generally westerly winds in western North America: Coastal Chinooks and interior Chinooks. The coastal Chinooks are persistent seasonal, wet, southwesterly winds blowing in from the ocean.
Unlike the prevailing winds in Southern California, which flow generally from west to east, carrying temperate air from the Pacific, the Santa Anas flow from northeast to southwest out of the ...
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.
Red flag warnings were active in several states across the central U.S. on Tuesday as forecasters say possible record-setting temperatures and high winds ahead of a cold front elevate the risk of ...
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
