In what stormy region do the westerlies and polar easterlies converge?
the polar front The westerlies and polar easterlies converge in the polar front.
What are westerlies and easterlies?
Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles. Polar easterlies flow to low-pressure areas in sub-polar regions. Westerlies. Westerlies are prevailing winds that blow from the west at midlatitudes.
What would easterly wind belts on either side of the equator be called?
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region.
What are the different global winds?
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 type of weather would you expect to encounter along the intertropical convergence zone?
The Inter-Tropical Convergence Zone (ITCZ – pronounced "itch") appears as a band of clouds consisting of showers, with occasional thunderstorms, that encircles the globe near the equator. The solid band of clouds may extend for many hundreds of miles and is sometimes broken into smaller line segments.
Which pressure zone do the trade winds diverge?
trade wind, persistent wind that blows westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone (ITCZ).
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.
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.
Why are polar global winds called polar easterlies?
The Polar Easterlies form when the atmosphere over the poles cools. This cool air then sinks and spreads over the surface. As the air flows away from the poles it is turned west due to the Coriolis Effect. Again, because these winds begin in the east, they are called easterlies.
Why do polar easterlies occur?
Why are Polar Easterlies Cold and Dry? Polar easterlies occur in some of the coldest parts of the world. They emerge from the polar highs, which are areas of high atmospheric pressure. These polar highs are areas in dry and cold regions, which explains why the polar easterly winds are also dry and cold.
What is the name of the belt where the tropical easterlies converge?
The Inter Tropical Convergence Zone, or ITCZ, is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together.
Where do westerlies come from?
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.
Which pressure belt is known as doldrums?
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator.
Where would I find 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.
Where do westerlies occur?

Where do the polar easterlies come from?
Polar easterlies occur in some of the coldest parts of the world. They emerge from the polar highs, which are areas of high atmospheric pressure. These polar highs are areas in dry and cold regions, which explains why the polar easterly winds are also dry and cold.

Where are polar easterlies located?
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.
Where are polar westerlies located?
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.
Why is equatorial low pressure belt called doldrums?
The temperature is high in the Equatorial regions creating a low pressure belt in the region. Winds in this pressure belt donot blow at a fast pace and hence this belt is also known as the Belt of Calms or the Belt of Doldrums.
Which pressure belt is known as the ITCZ and why?
The Inter Tropical Convergence Zone, or ITCZ, is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. It is characterised by convective activity which generates often vigorous thunderstorms over large areas.

What latitude do polar easterlies westerlies and trade winds occur?
Polar Easterlies: From 60-90 degrees latitude. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies). Tropical Easterlies: From 0-30 degrees latitude (aka Trade Winds).
Where is the location of westerlies?
mid-latitudes Where are the Westerlies Located? The westerlies occur in the mid-latitudes. The mid-latitudes are the areas between 30 and 60 degrees north and south of the equator. Places within these regions include the US, Canada, Europe, Southern Australia, and Chile.
Where do polar easterlies come from?
Polar easterlies occur in some of the coldest parts of the world. They emerge from the polar highs, which are areas of high atmospheric pressure. These polar highs are areas in dry and cold regions, which explains why the polar easterly winds are also dry and cold.
What happens when westerlies and easterlies meet?
When Westerlies and easterlies meet, a polar front is formed. The cool polar air meets the warmer mid-latitude air near the 60th parallel, where the warmer air rises over the colder air. This zone is known as the polar front.
What is Polar high pressure belt?
Polar high pressure areas At the North and South Poles, between 700 to 900 North and South, the temperatures are always extremely low. The cold descending air gives rise to high pressures over the Poles. These areas of high pressure are known as the Polar Highs. These regions are characterised by permanent Ice Caps.
Where is the doldrums belt located?
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator.
Which pressure belt is called doldrums?
The "doldrums" is a popular nautical term that refers to the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters. This NASA satellite image shows the Inter-Tropical Convergence Zone, known to sailors around the world as the doldrums.
Which pressure belt is called the Belt of doldrums?
Equatorial trough of low pressure Equatorial trough of low pressure is the zone of convergence of trade winds blowing equatorward from the sub-tropical belts of high pressure in the northern and southern hemisphere. Within this belt the winds are light and variable with frequent calms. That is why this belt is also known as doldrums.
