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 ]
The westerlies (blue) and trade winds (yellow and brown) Global surface wind vector flow lines colored by wind speed from June 1, 2011 to October 31, 2011. 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 ...
The westerlies (blue arrows) and trade winds (yellow and brown arrows) 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 ...
Westerly winds blowing across the Atlantic bring moist air into Europe. In years when westerlies are strong, summers are cool, winters are mild and rain is frequent. If westerlies are suppressed, the temperature is more extreme in summer and winter leading to heat waves, deep freezes and reduced rainfall. [7] [8]
Alberta Clipper (fast-moving, frigid winter wind out of the central Canadian plains that swoops down across the U.S. Plains, Midwest and Great Lakes) Brookings Effect (off-shore wind on the southwestern Oregon coast, United States; also known as the Chetco Effect) Chinook (warm dry westerly off the Rocky Mountains)
Meanwhile, in the Atlantic, fast-blowing upper level Westerlies of the Hadley cell form, which would ordinarily be blocked by the Walker circulation and unable to reach such intensities. These winds disrupt the tops of nascent hurricanes and greatly diminish the number which are able to reach full strength. [13]
She challenges anyone dreading the extra time inside to make a winter bucket list full of fun goals: going snowshoeing or ice-skating, creating an 8-foot-tall snowman, hosting a neighborhood ...
A western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent, [1] [2] which extends as east as up to northern parts of Bangladesh and South eastern Nepal. [3] It is a non-monsoonal precipitation pattern driven by the westerlies.
