What kind of air descends in the 30 degrees latitudes?
Along the equator the rising air creates a low pressure region called the doldrums , or the Intertropical Convergence Zone (ITCZ)(convergence zone because this is where the trade winds converge). At 30o latitude there are high pressure zones of descending air known as the horse latitudes , or the subtropical highs.
Why does air sink at latitude of 30 degrees?
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. The sinking air reaches the surface and flows north and south.
Does air rise or sink at 30 degrees north?
30 degrees N & S Latitudes: air sinks causing a drying effect. Many deserts in this region. Also called the Horse Latitudes because lack of wind caused sailors to become becalmed.
Why does wind between the equator and 30 south come out of the southeast?
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 is the climate at 30 degrees latitude?
deserts At 30 degrees latitude, the dry air creates deserts. Major deserts of the world, including the Sahara, Arabian, Gobi, Great Victoria, Kalahari, Atacama, and the Chihuahuan/Sonoran deserts occur around 30° N or 30° S.
What is located at 30 degrees south latitude?
The 30th parallel south is a circle of latitude that is 30 degrees south of the Earth's equator….Around the world.
| Co-ordinates | Country, territory or ocean | Notes |
|---|---|---|
| 30°0′S 29°1′E | South Africa | KwaZulu-Natal – passing just south of Durban |
| 30°0′S 30°57′E | Indian Ocean |
What kind of weather is associated with sinking air 30 degrees north and south of the equator?
When it reaches about 30° north and south, the air cools and sinks towards the ground forming the subtropical high-pressure zone. As the air sinks, it becomes warmer and drier. This creates an area of little cloud and low rainfall, where deserts are found.
What is the prevailing wind direction at a latitude of 30 degrees north?
What is the prevailing wind direction at a latitude of 30 degrees north? 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 wind systems move air from about 30 to 60 north or south latitude?
Trade winds Describe the movement of air in the huge convection current between 30° and 60° south latitude.
Which climate types are typically located around 30 degrees north and south?
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.
What type of biome is typically found at 30 degrees north and south latitude?
Desert Biomes Deserts generally occur in a band around the world between 15–30° N and S latitude (Figure 4). They cover between 26–35% of the land surface of the Earth.
What is latitude 30 degrees north?
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).
Where is the 30th latitude?
The 30th parallel north is a circle of latitude that is 30 degrees north of the Earth's equatorial plane. It stands one-third of the way between the equator and the North Pole and crosses Africa, Asia, the Pacific Ocean, North America and the Atlantic Ocean.
What is the convection pattern between 30 south and 30 latitude?
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.
What wind belt is located at 30 degrees north and 30 degrees south?
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 wind systems move air from about 30 degrees north or south latitude toward the equator?
What wind systems move air from about 30° north or south latitude toward the equator? The northeast trade winds in the northern hemisphere and the southeast trade winds in the southern hemisphere.
What is the direction of the winds between 30 60 degrees?
the east Between thirty and sixty degrees latitude, the winds that move toward the poles appear to curve to the east. Because winds are named from the direction in which they originate, these winds are called prevailing westerlies.
What biome is typically found at 30 degrees north and south latitude Why?
Deserts cover around 20% of the Earth and are on every continent. They are mainly found around 30 to 50 degrees latitude, called the mid-latitudes.
Which of the following is found along 30 degrees north and 30 degrees south?
The horse latitudes The horse latitudes are regions located at about 30 degrees north and south of the equator. These latitudes are characterized by calm winds and little precipitation. The horse latitudes are located at about 30 degrees north and south of the equator.
Why are deserts found at 30 degrees latitude?
Most of the world's deserts are located near 30 degrees north latitude and 30 degrees south latitude, where the heated equatorial air begins to descend. The descending air is dense and begins to warm again, evaporating large amounts of water from the land surface. The resulting climate is very dry.
What is the convection pattern between 30 degrees south and 30 north latitude?
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.
What are the prevailing winds between 30 N and 60ºn latitude?
The westerlies are the prevailing winds between 30° and 60° latitude. In the Northern Hemisphere, the westerlies are southwest winds. That is, they blow from the southwest to the northeast. In the Southern Hemisphere, the westerlies are northwest winds.
What wind system moves air from about 30 to 60 north or south latitude?
Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies).
What is the wind system from 0 degree to 30 degrees north latitude?
These are the so-called Polar Easterlies. An identical process occurs between the Equator line (0 degrees) and 30 degrees (northern and southern hemispheres). These are the so-called Trade Winds.
What biome is at 30 degrees latitude?
Deserts Deserts cover around 20% of the Earth and are on every continent. They are mainly found around 30 to 50 degrees latitude, called the mid-latitudes.
What is the convection pattern between 30 S and 30 N latitude?
In the zone between about 30° N. and 30° S., the surface air flows toward the Equator and the flow aloft is poleward. A low-pressure area of calm, light variable winds near the equator is known to mariners as the doldrums. The circulation pattern of the Earth's atmosphere.
Why do deserts form at 30 degrees latitude quizlet?
Why are many of the world's deserts found at 23 to 30 degrees latitude? Descending air masses warm as they go, absorbing more water vapor.
Why are there deserts at 30 degrees N and S and in polar regions?
1: Earth's two Jet Streams. The stronger Polar Jet is associated with low pressure. When the Polar Jet moves from its normal average location of 60°, it brings low pressure to desert regions near 30°.
What wind systems move air from 30 degrees north or south latitude toward the equator?
What wind systems move air from about 30° north or south latitude toward the equator? The northeast trade winds in the northern hemisphere and the southeast trade winds in the southern hemisphere.
What pressure belt is located at 30 degrees north?
Subtropical High-Pressure Belts (ii) Subtropical High-Pressure Belts At about 30°North and South of Equator lies the area where the ascending equatorial air currents descend. This area is thus an area of high pressure. It is also called as the Horse latitude. Winds always blow from high pressure to low pressure.
