What are trade winds explain?
The trade winds are winds that reliably blow east to west just north and south of the equator. The winds help ships travel west, and they can also steer storms such as hurricanes, too. … The trade winds are air currents closer to Earth’s surface that blow from east to west near the equator.
Are trade winds constant?
Near the equator, the sun heats the sea surface, causing the warm air at the surface to rise and be replaced by the trade winds blowing from subtropical high pressure systems into equatorial low-pressure troughs. The trade winds blow steadily for days and are among the most consistent on earth.12 мая 2020 г.
Why westerlies are called anti trade winds?
The directions of the Westerlies are opposite to trade winds and that is why they are also called antitrade winds. The currents in the Northern Hemisphere are weaker than those in the Southern Hemisphere due to the differences in strength between the Westerlies of each hemisphere. …
How are trade winds named?
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. … 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).
What are the main features of trade winds?
The main characteristics of the Trade winds are:
- The Trade winds blow in the tropics between the sub tropical high pressure belt to the equatorial low pressure belt between 30°N and 30°S.
- Trade winds are warm winds and hence they pick up moisture and bring heavy rainfall on the eastern sides of the tropical islands.

Are trade winds cold?
The trade winds, especially in the eastern Pacific, convey relatively cool air toward the Equator; in moving, the air comes in contact with the sea and thus becomes increasingly humid and warm, and high lapse rates (the term used to denote the rate of change of air temperature with increasing height above sea or land …
Why are northeast trade winds dry?
Trade winds originate over land and they don’t carry much of moisture.. This cause lack of rainfall in the regions they blow over and causes dry atmosphere..
What are Hawaii trade winds?
Trade winds in Hawaii are a phenomenon that occur as a result of high pressure systems that form in the North Pacific. They are generally a very steady presence in island weather and bring a constant wind or breeze from the North East or East North East directions.
What are the three types of wind?
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10).
What is the difference between trade winds and westerlies?
Trade winds are the winds that flow from subtropical high-pressure belts to equatorial low-pressure belts. Westerlies are winds that flow from subtropical high-pressure belts to subpolar/circumpolar low-pressure belts. Both are permanent winds.
Why are they called westerlies?
The name of these unique winds comes from the direction of their origin; the westerlies run west to east while other winds run east to west. … This distinction is due to the air pressure over the poles during the winter.
What height is wind speed?
Average wind speeds are often available from meteorological observations measured at a height of 10 metres.
Who Discovered trade winds?
Christopher Christopher Columbus
