Air in motion is called wind.Usually the wind starts moving towards a low pressure area from a high pressure area.As the winds converge at the low pressure area from the sorrounding area,they are forced to rise.As they rise,they become colder and sinks usually over a high pressure area.So there is a reverse flow at higher levels completing the cycle.So,there is a circulation consisting of a wind flow from higher to lower pressure areas at surface level and corresponding reverse flow at higher levels.This is how a wind circulation is created causing the windflow.There are three such global circulations from the Equator towards the poles as four alternate low and high pressure belts exist due to differential heating of the surface by the sun.

Nobody knows, not even Jesus.
In the Gospel according to John, chapter 3, verse 8, he says to Nicodemus "The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes".
A.A. Milne didn't know either, in "Now we Are Six" :-
If I stopped holding
The string of my kite,
It would blow with the wind
For a day and a night.
And then when I found it,
Wherever it blew,
I should know that the wind
Had been going there too.
So then I could tell them
Where the wind goes...
But where the wind comes from
Nobody knows.

Heat from the sun warming the earth causes movement of air (HOT AIR RISES).This causes an area of low pressre which attract higher pressure area. That movement is called wind. Also as the earth rotates wind is produced, from the West in the northern hemisphere and from the East in the southern - called the coriolus effect.

Wind is the movement of air from a region of high pressure to a region of
lower pressure. These areas of high and low pressure arise from temperature
differences caused by the sun heating the earth, which in turn heats the
atmosphere.
