Think of the air at the Equator as a column. If you heat it, the air in the column expands and rises, cooling as it does so. As the column gets taller, at altitude you have relatively higher pressure, and the air flows out towards a lower pressure area. When the air flows out from the top of the column, it leaves lower pressure at the surface.
The opposite happens at the poles where the air is cold and dense. The column is shorter and heavier than the column at the Equator. The pressure is lower at altitude and so the high pressure air from the Equator flows there. Adding air to the top of the polar column raises the surface pressure and the air flows from there to a lower pressure area at the equator.
So you get a circulation, out from the Equator to the poles at high level, and in towards the Equator at lower level. The air that left the Equator was warm when it was on the surface at the Equator, but by the time it has risen 40,000-50,000 feet and traveled several thousand miles at high altitude, it is no longer warm.
The rotation of the earth and the roughness of the terrain affect the flow greatly, and the air at the surface tends to turn to the right causing rotating areas of high and low pressure.

What takes the place of warm air?
As the warm air rises and moves toward the poles,cooler air moves from the poles toward the equator to replace it. Resource:Factors of Weather:Air movement Close to the Earth (science sheet)
Is a maritime tropical air mass warm and humid or dry?
dry
What is a warm wet tropical forest is called?
A warm wet tropical forest is called a rainforest.
Which air masses have warm moist air?
The air masses that have warm moist air are the maritime tropical air masses, which form over warm ocean waters. These air masses bring warm, humid conditions and are typically responsible for summer showers and thunderstorms.
What are the three major climate zones on earth?
The three major climate zones on Earth are tropical, temperate, and polar. The tropical zone is located near the equator and is characterized by warm temperatures year-round. The temperate zone is found between the tropical and polar zones and experiences distinct seasons. The polar zone is located near the poles and has cold temperatures throughout the year.
Where does Warm tropical water flows towards?
Poles
What is the circulation of tropical air?
The circulation of tropical air is driven by the Hadley cell, a large-scale atmospheric circulation pattern that transports warm air from the tropics towards the poles and cold air from the poles towards the tropics. This circulation plays a key role in shaping global weather patterns and climate.
What is the difference between tropical and polar climate?
A tropical climate is warm all year around, while a polar climate is cold all year around.
Can tropical rainforests occur in a belt around the earth poles?
No, tropical rainforests do not occur in a belt around the Earth's poles. They are typically found near the equator, where temperatures are warm and precipitation is high year-round. The climate conditions necessary for tropical rainforests, such as consistent warmth and humidity, are not present in polar regions. Instead, polar areas are characterized by cold temperatures and limited vegetation.
Do tropical fish live in warm or cold water?
they live in warm water because tropical areas are warm
Cool air over the poles will?
Actually, cool air tends to be more dense and flow under warm air
What is the difference between a tropical and polar air mass?
A tropical air mass originates in the lower latitudes (closer to the equator) and is generally warm. A polar air mass originates in the higher latitudes (closer to one of the poles) and is generally cold.
What takes the place of warm air?
As the warm air rises and moves toward the poles,cooler air moves from the poles toward the equator to replace it. Resource:Factors of Weather:Air movement Close to the Earth (science sheet)
Where do warm currents move from?
Warm currents move from the equator to the poles, and the cold currents move from the poles to the equator. :D
Why are tropical islands hot?
Because the word tropical means warm and cool like warm and breezy
What is maritime tropic?
Tropical maritime is a weather term referring to air masses, Tropical means warm-usually from tropical areas. maritime means moist, as in air masses that originated or travelled over a large body of water. Tropical maritime would describe a warm, moist air mass. The opposite would be polar,continental, referring to air masses originating near the poles and over land. This would be dry, cold air.
How warm is the tropical ocean biome?
It is pretty warm.
