What are the 4 types of wind patterns?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
What are the various categories of wind explain with a diagram?
There are three main types of planetary winds – the trade winds, the westerlies and the easterlies. These winds are named according to the direction from which they blow. north and south of the Equator to the sub polar low pressure belt. In the Northern Hemisphere, they blow from SW to NE.
What are westerlies and easterlies?
When air moves in a definite direction, it is called wind. If the winds move from west to east, they are called westerlies. If they move from east to west, they are called easterlies. There are winds because there are differences in pressures. The direction of wind is also affected by coriolis affect.
Are trade winds easterlies?
Trade winds can be defined as the wind that flows towards the equator from the north-east in the Northern Hemisphere or from the south-east in the Southern Hemisphere. These are also known as tropical easterlies and are known for their consistency in force and direction.
How westerlies are formed?
Westerlies are formed due to high-pressure systems within the mid-latitudes. The hot air near the equator rises, and the cold air from surrounding areas replaces the hot air. The air begins to circulate, which is how the westerlies are formed.
What are polar easterlies?
The polar easterlies are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards low-pressure areas within the Westerlies at high latitudes.
Where are the polar easterlies?
The polar easterlies are one of the five primary wind zones, known as wind belts, that make up our atmosphere’s circulatory system. This particular belt of wind begins at approximately 60 degrees north and south latitude and reaches to the poles.
How are polar easterlies formed?
Polar Easterlies Winds form as they more from high pressure areas near the poles toward the low pressure areas 30 degrees below each of the poles. You can see from the pictures that these winds blow from the East to the West. The winds are therefore called Polar Easterlies.
What are the easterlies and westerlies?
When air moves in a definite direction, it is called wind. If the winds move from west to east, they are called westerlies. If they move from east to west, they are called easterlies. There are winds because there are differences in pressures.
Where are the westerlies?
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.
Whats the definition of westerlies?
1 : situated toward or belonging to the west the westerly end of the farm. 2 : coming from the west a westerly breeze. westerly.
What is the meaning of polar easterlies?
What are trade winds or easterlies?
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).
What are the polar easterlies?
The Polar easterlies are cold, dry permanent winds that blow from north-east to south-west direction in the Northern Hemisphere and south-east to the north-west in the Southern Hemisphere. Easterlies blow from the high-pressure polar areas of the subpolar lows.
What happens to trade winds during the Arctic oscillation?
When the phase of the Arctic oscillation (AO) is warm, trade winds are stronger within the tropics. The cold phase of the AO leads to weaker trade winds. When the trade winds are weaker, more extensive areas of rain fall upon landmasses within the tropics, such as Central America.
What are the trade winds called in the northern hemisphere?
Because winds are named for the direction from which the wind is blowing, these winds are called the northeasterly trade winds in the Northern Hemisphere and the southeasterly trade winds in the Southern Hemisphere. The trade winds of both hemispheres meet at the Doldrums.
