[22], During mid-summer in the Northern Hemisphere (July), the westward-moving trade winds south of the northward-moving subtropical ridge expand northwestward from the Caribbean sea into southeastern North America (Florida and Gulf Coast). A low-pressure area of calm, light variable winds near the equator is known as the doldrums,[7] near-equatorial trough,[8] intertropical front, or the Intertropical Convergence Zone. Some of the descending air supplies the trade winds and goes back to the Equator; some of it moves to the northeast in the Northern Hemisphere and to the southeast in the Southern Hemisphere, and forms, in both Temperate Zones, the prevailing westerly winds. The trade winds of both hemispheres meet at the doldrums. Todd. The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region (between 30°N and 30°S latitudes). 1 mph 3 mph 5 mph 10 mph 15 mph 30 mph.

Become a Study.com member to unlock this This warm, dry air is known as a superior air mass and normally resides above a maritime tropical (warm and moist) air mass. These upper currents are the anti-trade winds. The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region (between 30°N and 30°S latitudes). The following is a screen print of the wind map for North America with Saskatchewan shown by the black rectangle at the top of the map.

[24] Since 1970, dust outbreaks have worsened due to periods of drought in Africa. 0 0. Those that develop over land (continental) are drier and hotter than those that develop over oceans (maritime), and travel northward on the western periphery of the subtropical ridge. [20] When the phase of the Arctic oscillation (AO) is warm, trade winds are stronger within the tropics. You can sign in to vote the answer. "Since the earth's surface is warmer in the equatorial regions than it is in the temperate or polar regions, the air is expanded and its upper parts flow off to the north and south towards the poles.

[3], By the 18th century, the importance of the trade winds to England's merchant fleet for crossing the Atlantic Ocean had led both the general public and etymologists to identify the name with a later meaning of "trade": "(foreign) commerce". Its presence negatively impacts air quality by adding to the count of airborne particulates. These units are often used by sailors, kiters, surfers, windsurfers and paragliders. At the same time the cooler air at the surface of the earth at the north and south of the equatorial calm belt moves in and forces the warm air to higher levels.
