Input: The westerlies, anti-trades, 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 and trend towards the poles and steer extratropical cyclones in this general manner. Tropical cyclones which cross the subtropical ridge axis into the westerlies recurve due to the increased westerly flow. The winds are predominantly from the southwest in the Norther Historical Importance. 1 Trade winds have been used by captains of sailing ships to cross the oceans. The term trade winds originally derives from the early fourteenth century late Middle English word 'trade' meaning path or track.. 1.

It is better to enter a port or beach during the daytime because of which of the following? summer monsoon. winter monsoon. land breeze. sea breeze. Trade Winds Trade winds were introduced in Chapter 1 (Global weather patterns) as the equatorward blowing part of the Hadley cell. Because many cruising boats spend a lot of time in the trade wind region, some more detailed information is given in this chapter. Typical trade wind characteristics. The strength of the trade winds - like all the winds in the world - is predominantly determined by pressure gradient. Because the pressure of the equatorial trough, or ITCZ, is relatively stable at around 1008-1012 hPa, the strength of the trade winds is mostly determined by the strength and location of the subtropical high pressure. The low pressure is caused by the heatat the equator, which makes the air rise and travel north and southhigh in the atmosphere, until it subsides again in thehorse-latitude. Some of that air returns to the Doldrums throughthe trade-wind. Where do the trade winds occur? What are high altitude winds that occur in places where trade winds and polar easterlies meet prevailing weste? The trade wind normally strengthens just before an el nine occurs? More questions Trade Winds. In the Northern Hemisphere, warm air around the equator rises and flows north toward the pole. As the air moves away from the equator, the Coriolis effect deflects it toward the right. It cools and descends near 30 degrees North latitude. The descending air blows from the northeast to the southwest, back toward the equator (Ross, 1995). A similar wind pattern occurs in the Southern Hemisphere; these winds blow from the southeast toward the northwest and descend near 30 degrees South latitude. These prevailing winds, known as the trade winds, meet at the Intertropical Convergence Zone (also called the doldrums) between 5 degrees North and 5 degrees South latitude, where the winds are calm. The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies. The trade winds are so named because ships have historically taken advantage of them to aid their journies between Europe and the Americas (Bowditch, 1995). The westerlies (blue arrows) and trade winds (yellow and brown arrows) The trade winds are the prevailing pattern of easterly surface winds found in the tropics, within the lower portion of the Earth's atmosphere, in the lower section of the troposphere near the Earth's equator. The trade winds blow predominantly 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. Trade winds have been used by captains of sailing ships to cross the worl The names for the regions of the earth known as the trade winds, horse latitudes, and the doldrums all hark back to the age of sailing. Learn about these regions from your About.com Guide to Geography. Within the convergence zone, the average winds are slight and often non existant, unlike the zones north and south of the equator where the trade winds feed in.. Early sailors using ships powered by sails named this belt of calm The Doldrums because of the inactivity and stagnation they found themselves in after possibly long periods of no wind.. Query: at what latitudes do the trade winds occur
Output:
As the air moves away from the equator, the Coriolis effect deflects it toward the right. It cools and descends near 30 degrees North latitude.
