why the magnitude of precipitation is not evenly distributed?

Question 1

What happens first?

-Equator

Answer 1

Solar radiation is intense over the Equator.

Question 2

What happened 2nd?

-Evaporation

Answer 2

Evaporation takes place and water vapour rises creating an area of low pressure

Question 3

What happens 3rd?

-Air rises

Answer 3

As air rises it cools and at the dew point condenses into cloud

Question 4

What happens 4th?

-rain drops

Answer 4

Once the raindrops reach a certain size they fall, due to gravity, as precipitation

Question 5

What happens 5th?

-cool air

Answer 5

The cool air reaches the top of the troposphere and moves north and south away from the Equator

Question 6

What happens 6th?

-air cools

Answer 6

As the air cools it becomes more dense and sinks over the tropics

Question 7

What happens 7th?

-air descends

Answer 7

The air descends over the tropics and heats up creating area of high pressure

Question 8

What happens 8th?

-dry air

Answer 8

This dry air creates cloudless skies and no precipitation over the tropics

Question 9

What happens 9th?

-surface

Answer 9

When the air reaches the surface it moves north, and south back towards the ITCZ

Question 10

What is this know as?

Answer 10

This is known as the Hadley cell.
