What weather do you experience during low pressure?
Rainfall
What weather do you experience during high pressure?
heat and hot sun
Where do you find the Hadley cells?
On the equator
How is the Hadley cells formed?
The ground is heated by the sun. The air rises which causes low pressure . Then it condenses and sinks at 30 degrees north and south creating an area of high pressure.
Where do you find the ferrel cells?
In the higher latitudes
How do ferrel cells form?
Air is pulled towards the poles. This forms warm winds at the hemispheres. Then the wind picks up moisture as they travel over the oceans.
What is the climate of the uk?
Temperate climate because the it gets warm in the summers and cold in the winters.
Describe the relationship between air pressure and surface winds.
Sinking air causes high pressure which leads to the winds moving away from each other.
