×Where does the weather come?
Heat from the Sun
The quantity of the sun light which the earth
receives is highest around the Equator, and
it decreases most in the North Pole and the
South Pole.
Heat transport
These three huge air circulations from the
Equator to the Pole carry the heat from the
Equator to the Pole to balance the heat of
earth.

Atmospheric general circulation
Air is warmed at the Equator and goes up
to the tropopause to a height of 16km.
The air is stopped rising by the tropopause
flows towards to north and south, then descends
again near 30 degrees of each of the north
latitude and the south latitude, and has
made the high pressure belt (subtropical
high-pressure belt). The flow of this air
is called Hadley Circulation. The lower stream
of Hadley Circulation is transrated into
"the Easterly" because the Coriolis
force bends the wind on the right from the
original direction(in the Northern Hemisphere).
Hadley Circulation makes the Ferrel Circulation.
This Ferrel Circulation in transrated into
"the Westerlies".
In the North Pole and the South Pole, the
cold air flows down to middle latitude and
makes the Pole circulation which returns
to a Pole again..

Coriolis force
The Coriolis force works from left to right
[ 90 degrees ] to the advance direction of
wind in the Northern Hemisphere.
In the Southern Hemisphere, it works leftward
[ 90 degrees ] to the advance direction of
wind Air moves toward from the higher atmospheric
pressure to the lower area.
The flow of this air is "the wind".
The actual direction of a wind is changed
into the other direction because of the Coriolis
force. In the Northern Hemisphere, a wind
is bent on the right from the original direction,
and is bent on the left in the Southern Hemisphere.
