Q

Africa in July

A

South west wet monsoon
Airflow from the subtropical high pressure belt get deflected to the right and hits the western coast of Africa, Nigeria

As the air hits the land it can cause very unstable conditions with lots of convective cloud

South east trades become sw

Q

India in July

A

South west wet monsoon

High pressure of the Indian Ocean gets deflected to the right when it passes the equator and effects the south west coast of india by creating convective clouds in that location

Se trades become sw

A

N Australian n w monsoon

Air from the massive Siberian high get deflected at the equator and head towards n Australia this is helped by the n Australian low also

Q

E Asia and India in jan

A

Ne dry monsoon

Siberian high sends air over large land masses, not much weather due to travelling over large land masses

Q

Africa in jan

A

The harmattan is greater and covers more land and therefore making it more dangerous.
ITCZ moves down so does the sub tropical high pressure belt

Can result in stranded air pools

A

Can last for a few days, 300 to 600 in diameter
Can extend vertically 10x30,000 ft
Not visible on surface pressure charts
Can contain intense unstable conditions
