What Is The Overall Direction Of Global Air Currents At The Equator


What Is The Overall Direction Of Global Air Currents At The Equator?

In the tropics near the equator warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles. Air that rose just north of the equator flows north. Air that rose just south of the equator flows south.

What is the overall direction of global air currents at the?

What is the overall direction of global air currents at the equator? Air currents sink at the equator.

What is the best explanation for the high amounts of rain that occur at the equator *?

Areas near the equator receive high rainfall amounts because constant solar heating produces intense heating large-scale evaporation moist rising air that cools with altitude and forms convectional rainfall. In addition air masses converge here which results in heavy rainfall.

Which type of area would you expect to find along the equator?

An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The Earth is widest at its Equator.

Which type of weather would you expect to find at the intertropical convergence zone?

The rising air produces high cloudiness frequent thunderstorms and heavy rainfall the doldrums oceanic regions of calm surface air occur within the zone. The ITCZ shifts north and south seasonally with the Sun.

What is the air that sinks at latitudes of 30 degrees north and south like?

What is the air that sinks at latitudes of 30 degrees north and south like? This air is cool and dry.

What is the correct order of the convection cells starting from the equator?

Hadley Ferrel Polar “.

Why does the equator receive so much rain?

The air above the Equator is very hot and rises creating an area of low pressure. The Equator experiences high amounts of rainfall due to this rising air resulting in a warm and wet equatorial climate (eg the Amazon and Congo tropical rainforests). … This is because sinking air does not result in precipitation.

Why does it rain more in the North?

Why do some places get more rain than others? … This is because the mountains of the northern and western UK force the prevailing westerly winds to rise which cools the air and consequently enhances the formation of cloud and rain in these locations (this is known as orographic enhancement).

Does it rain at the equator?

It is a common fact that equatorial regions receives highest rainfall (to the tune of 4000 mm in a year). … Raining occurs everyday or every alternate day over equatorial region making it wettest on earth resulting them at an average 22 days wet in a month.

Where is the equator at?

0 degrees latitude

The equator is 0 degrees latitude and the prime meridian is 0 degrees longitude. The equator is the halfway point between the North Pole and the South Pole. It runs from side to side across the middle of the Earth through parts of South America Africa and Asia.

Is the Antarctic Circle North or South equator?

The Antarctic Circle is a parallel of latitude on the Earth at approximately 66.5 degrees south of the equator. On the day of the southern summer solstice (around December 22 each year) an observer on the Antarctic Circle will see the Sun above the horizon for a full 24 hours.

Which continents does the equator cross?

The EQUATOR cross through these continents: South America Africa and Asia.

Why is ITCZ north of equator?

ITCZ stands for Intertropical Convergence Zone. It is a region of clouds rain low level convergence and rising air. … The ITCZ has a mean position north of the equator because there is much more landmass in the Northern Hemisphere as compared to the Southern Hemisphere.

What is ITCZ Class 9 Brainly geography?

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 region of the Earth does the sun hit at the most direct angle?

the equator
The sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly the area is heated more. You can see this in the figure below.

Why does air sink at 30 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.

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.

What is the prevailing wind direction at a latitude of 30 degrees north?

prevailing 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.

Which list is the correct order of atmospheric layers starting from Earth’s surface?

Starting from earth’s surface the six layers are Troposphere Stratosphere Mesosphere Thermosphere Ionosphere and Exosphere.

At what latitudes are the three convection cells in the northern and three in the southern hemisphere?

Equals Three Convection Cells

The Ferrell cell is between 30°N and 50° to 60°N. This cell shares its southern descending side with the Hadley cell to its south. Its northern rising limb is shared with the Polar cell located between 50°N to 60°N and the North Pole where cold air descends.

How does air move in convection cells?

When you warm air it rises. Cool air will sink. … Ultimately the motion leads to a convection cell with air rising moving to the side falling and moving back. This heat-driven motion of air moves heat around in the atmosphere.

What happens to the air at the equator?

Air rises at the equator leading to low pressure and rainfall. When the air reaches the edge of the atmosphere it cannot go any further and so it travels to the north and south. The air becomes colder and denser and falls creating high pressure and dry conditions at around 30° north and south of the equator.

Why is the equator hot?

Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. … This means more heat from the sun makes it to the surface of the Earth.

Is the equator wet or dry?

At the equator there are two wet and two dry seasons as the rain belt passes over twice a year once moving north and once moving south. Between the tropics and the equator locations may experience a short wet and a long wet season and a short dry and a long dry season.

Does it snow in England?

On average across the UK there are only 15.6 days a year when snow is on the ground compared to 26.2 days in Scotland. Again most of the snow on the ground can be found in mountainous areas.

Why does it always rain in London?

Why Britain gets so much rain

The Gulf Stream is just one of those ocean currents transporting relatively warm water from the Gulf of Mexico to the British Isles. Warm water evaporates faster than cool water and when you consider that the UK is surrounded by sea it becomes clear why we’re particularly prone to rain…

Why does it rain in the UK?

Prevailing winds bring warm moist air to the western British Isles. Air is forced to rise over high areas. Air cools and condenses. Clouds form and it rains.

Why is the equator tropical?

Tropical rainforests are found near the equator due to the amount of rainfall and the amount of sunshine these areas receive. … The high temperatures means that evaporation happens at a fast rate resulting in frequent rainfall.

Why does the Sahara get no rain?

Hot moist air rises into the atmosphere near the Equator. … As it approaches the tropics the air descends and warms up again. The descending air hinders the formation of clouds so very little rain falls on the land below. The world’s largest hot desert the Sahara is a subtropical desert in northern Africa.

What is the coldest zone of the earth?

What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.

Where is the equator in Asia?

In Asia there are two countries where the Equator passes. These are Maldives and Indonesia.

Why is the equator placed where it is on the world map?

The Equator represents the great invisible circle around the Earth that is everywhere equidistant from the geographic poles and lies in a plane perpendicular to the Earth’s axis. The Equator divides the Earth into the Northern and Southern hemispheres. In other words it is the line with 0° latitude.

Where is the equator in the United States?

The U.S. state closest to the equator is Hawaii. At its southernmost tip the island state has a latitude of just under 19 degrees North latitude….
