Why are westerly winds the prevailing winds at latitudes of 30 60 N and 30 60 S?
Because of the rotation of the earth and the coriolis force, air is deflected to the right in the Northern Hemisphere.
In the circulation cell that exists between 60° and 30° north, the movement of air produces the prevailing westerlies.
In the tropic circulation cell, the northeast trade winds are produced..
What are the winds called below the latitude 60 degrees south?
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).
Why is the air pressure at the equator lower than the pressure at 30 N and 30 S?
Equatorial regions is hotter and the air above expands, becomes less dense and rises. This produces a low pressure belt at this latitude. 1. … 30o N & S latitudes are high pressure belts.
What are the 3 major wind systems?
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig.
How does the uneven heating of the earth cause wind?
Wind is the movement of air caused by the uneven heating of the Earth by the sun. … Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air.
Are trade winds warm or cold?
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.
What wind systems move air from about 30 degrees to 60 degrees north or south latitude?
WesterliesThe Prevailing Westerlies are located between 30 and 60 degrees latitude. In this zone, the winds blow toward the poles from the west. Prevailing westerlies in the Northern Hemisphere are responsible for many of the weather movements across the United States and Canada.
Why does air sink at 30 degrees latitude?
The air sink at 30 degree latitude as it is very cool enough at that time. Cooler air will have a higher density which will make the air to sink to the Earth surface create a high pressure area.
Does air rise or sink at 60 degrees latitude?
60 degrees N & S Latitudes: another area of rising air, not as strong as ITCZ. Prevailing Westerlies (in N Hemisphere): between ~60 degrees N&S latitudes and ~30 degrees N&S latitudes air blows towards the poles. 90 degrees N & S Latitudes: air sinks over the poles and moves equatorward.
Why does air subside at latitude 30 degrees in both hemispheres?
The location of the majority of earth’s driest and arid regions are located in the areas underneath the descending branches of the Hadley circulation around 30 degrees latitude, which also supports the 3 cell model. Air usually subsides at 30 degrees because at that latitude it is cool enough to allow it to sink.
What is the direction of the winds between 30 60 degrees?
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.
What are the 4 types of winds?
The Four Major Wind Systems and Wind Belts: 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.
At what degrees latitude can you completely sail around the world?
The 60th parallel south is a circle of latitude that is 60 degrees south of Earth’s equatorial plane. No land lies on the parallel—it crosses nothing but ocean.
Why is it called the Roaring 40s?
Sailors call the latitudes between 40 and 50 degrees south of the equator the Roaring Forties. … Warm air moving poleward (on both sides of the equator) is the result of nature trying to reduce the temperature difference between the equator and at the poles created by uneven heating from the sun.
What wind pattern occurs between 30 and 60 degrees north and south of the equator?
WesterliesMid-Latitude Westerlies Sometimes known as the prevailing westerlies or just the westerlies, these winds blow in a general west-to-east direction from about 30 to 60 degrees latitude.
What happens to the air at 30 degrees latitude?
At about 30 degrees latitude north and south, the cooled air descends back to the surface, pushing the air below it toward the equator, since air flows always move toward areas of low pressure.
Why does wind change direction?
So the air flows from high-pressure areas to low-pressure areas. … and as they move… the difference in pressure between these storms and high pressure systems surrounding them bring wind. The wind changes direction and speed based on how the low and high pressure move and the strength of each system.
Where is 60 degrees north latitude?
The 60th parallel north is a circle of latitude that is 60 degrees north of Earth’s equator. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. Although it lies approximately twice as far away from the Equator as from the North Pole, the 60th parallel is half as long as the Equator line.
