What is the name of the winds at 30 degrees north and 30 degrees south of the equator?

What is the name of the winds at 30 degrees north and 30 degrees south of the equator?

The horse latitudes are located at about 30 degrees north and south of the equator. It is common in this region of the subtropics for winds to diverge and either flow toward the poles (known as the prevailing westerlies) or toward the equator (known as the trade winds).

What causes air at 30 N and 30 S tend to move back towards the equator?

Between about 30 degrees north and 30 degrees south of the equator, in a region called the horse latitudes, the Earth’s rotation causes air to slant toward the equator in a southwesterly direction in the northern hemisphere and in a northwesterly direction in the southern hemisphere. This is called the Coriolis Effect.

What happens to the air from the equator when it reaches around 30 degrees north or south of the equator?

The air that rises at the solar equator descends near 30 degrees N or S. As the air mass strikes the ground in subtropical latitudes and spreads to the north and south, it draws moisture from the land, creating zones of arid climate centered at latitudes of about 30 degrees north and south of the equator.

Why is there high pressure at 30 degrees from the equator?

The air that rises at the equator does not flow directly to the poles. Due to the rotation of the earth, there is a build up of air at about 30° north latitude. Some of the air sinks, causing a belt of high-pressure at this latitude.

Why does the air that is sinking at 30 degrees north and south create deserts?

This warm, dry air can hold a lot of water, so the air starts to suck up what little water is around. At 30 to 50 degrees north and south of the equator, this falling air makes dry air drier. It also turns the land below it into a desert.

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. 3.10).

At what locations is water sinking?

Cold, salty, dense water sinks at the Earth’s northern polar region and heads south along the western Atlantic basin. The current is “recharged” as it travels along the coast of Antarctica and picks up more cold, salty, dense water.

Why is humidity lower at 30 degrees latitude?

At about 30 degree latitudes in both hemispheres (north and south), the air descends. As it does, it warms. As it warms, the air expands, condensation and precipitation are infrequent. As air moves inland, it gets depleted of moisture and precipitation drops.

Where is the Coriolis effect the strongest?

the poles
The Coriolis force is strongest near the poles, and absent at the Equator. Cyclones need the Coriolis force in order to circulate.

What happens at 20 30 degrees north and south of the equator to create a desert area?

Air at the equator rises and cools – condensation then forms rain. The air then moves north and south until it gets to about 30° north and south of the equator, where it sinks. Most moisture falls as rain before it reaches the land, eg the Namib Desert in Africa.

Is 30 Degrees North High or low pressure?

Between each of these circulation cells are bands of high and low pressure at the surface. The high-pressure band is located about 30° N/S latitude and at each pole. Low pressure bands are found at the equator and 50°-60° N/S.

Are air masses rising or sinking at 30 degrees north and south latitude?

Are air masses rising or sinking at 30 degrees north and south latitude? Due to the rotation of the earth, there is a build up of air at about 30° north latitude. (The same phenomenon occurs in the Southern Hemisphere). Some of the air sinks, causing a belt of high-pressure at this latitude.

Where does wind move away from high pressure?

On the surface, wind moves away from high pressure (High) and toward low pressure (Low). Convergence occurs near the equator (winds blow in towards one another) and Divergence occurs under the descending air that forms high-pressure belts.

What are the air circulation patterns on Earth?

Air circulation patterns Latitude Barometric Pressure Precipitation Surface winds 90° High Dry Divergent 60° Low Wet Convergent 30° High Dry Divergent 0° Low Wet Convergent

How does air rise and cool at high altitudes?

Source: Mike Arthur and Demian Saffer. The rising air creates a circulation cell, called a Hadley Cell, in which the air rises and cools at high altitudes moves outward (towards the poles) and, eventually, descends back to the surface.

What causes air to flow away from the surface?

On the other hand, sinking air creates high pressure at the surface where it descends. A gradient of pressure (high to low) is formed that causes air to flow away from the high and towards the low pressure at the surface.
