Weather Hazards
Global atmospheric circulation: pressure belts and surface winds
- 3 things to know
- Paper 1
Overview
What drives global circulation, the three cells, rising air at the equator and sinking air at 30°, the Inter-Tropical Convergence Zone, trade winds, westerlies and the Coriolis effect.

Key term
What drives the movement of air in the global atmospheric circulation system?
Key term
Name the three circulation cells found in each hemisphere, working from the equator to the pole.
Questions from this subtopic
Each one with the model answer underneath.
- 1
What drives the movement of air in the global atmospheric circulation system?
Model answer
The unequal heating of the Earth's surface, because the equator receives far more concentrated solar energy than the poles, so heat is moved polewards.
- 2
Name the three circulation cells found in each hemisphere, working from the equator to the pole.
Model answer
The Hadley cell, the Ferrel cell and the Polar cell.
- 3
Why is there a belt of low pressure at the equator?
Model answer
Intense heating makes the air rise, and rising air lowers the pressure at the surface.
- 4
What weather is typical underneath a belt of rising air?
Model answer
Cloud and heavy rainfall, because the rising air cools and its water vapour condenses.
- 5
Why do most of the world's hot deserts lie close to 30° north and south?
Model answer
Air sinking in the subtropical high pressure belt warms as it descends, so cloud cannot form and rainfall is very low.
- 6
What is the name of the zone near the equator where the trade winds of the two hemispheres meet?
Model answer
The Inter-Tropical Convergence Zone.
