​Rainfall factor (1) monsoon system

Monsoons are winds that change directions seasonally

Why are the winds changing directions?
They are formed by the differences in the heating of land and sea.
Change in temperature -> change in air pressure

P.18

​Rainfall factor (1) monsoon system

​Understand the difference between land and sea
-> different heating capacity

​Rainfall factor (1) monsoon system

​Understand the difference between land and sea
-> different heating capacity

Land: lower heating capacity
Sea: higher heating capacity

Land takes shorter to heat up or cool down.
Sea takes longer to heat up or cool down.

Remember a few rules:

1.high temperature → low pressure

2.hot air rises // cold air sinks

3.Air moves from high pressure to low pressure!
(Just like you! stressful → relax)

*Remember either summer or winter case, and the other is just the exact opposite!

​hot air rises up
-> low pressure

​cold air sinks
-> high pressure

​-> high
pressure

-> low
pressure
