How do westerlies form
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 … See more If the Earth were tidally locked to the Sun, solar heating would cause winds across the mid-latitudes to blow in a poleward direction, away from the subtropical ridge. However, the Coriolis effect caused by the rotation of Earth … See more An extratropical cyclone is a synoptic scale low-pressure weather system that has neither tropical nor polar characteristics, being connected with fronts and horizontal gradients in temperature and dew point otherwise known as "baroclinic zones". The descriptor … See more • Polar easterlies • West wind • Ferrel cell • Trade winds See more Due to persistent winds from west to east on the poleward sides of the subtropical ridges located in the Atlantic and Pacific oceans, ocean currents are driven in a similar manner in both hemispheres. The currents in the Northern Hemisphere are weaker than those in … See more When a tropical cyclone crosses the subtropical ridge axis, normally through a break in the high-pressure area caused by a system traversing the Westerlies, its general track around the high-pressure area is deflected significantly by winds moving towards the … See more WebOnce a hurricane reaches further north and enters the mid-latitudes, the environmental wind field usually becomes southwesterly or westerly, often around the western side of a high pressure system and east of a trough of …

If they move from east to west, they are called … WebAt about sixty degrees latitude in both hemispheres, the prevailing westerlies join with the polar easterlies to reduce upward motion. The polar easterlies form when the atmosphere over the poles cools. This cool air then sinks and spreads over the surface.
WebIn the U.S., westerlies cause cyclones to form east of large mountain ranges. Offshore of Cold Land Cyclones also form over water, offshore of cold land. This can occur during the colder times of the year, when the coastal land has cooled more rapidly than the adjacent water. Rising air over the ocean forms an area of low pressure just offshore.

WebFeb 28, 2024 · The trade winds blow toward the west partly because of how Earth rotates on its axis. The trade winds begin as warm, moist air from the equator rises in the atmosphere and cooler air closer to the poles sinks. The trade winds are created by a cycle of warm, moist air rising near the equator.
