Wind is caused by air flowing from high pressure to low pressure Since the Earth is rotating, however, the air does not flow directly from high to low pressure, but it is deflected to the right (in the Northern Hemisphere; to the left in the Southern Hemisphere), so that the wind flows around the high and low pressure areas. This effect of the wind "feeling the Earth turn underneath it" is important for very large and long-lived pressure systems. For small, short-lived systems (such as in the cold outflow of a thunderstorm) the wind will flow directly from high pressure to low pressure. ~i acctually got this answer from Yahoo answers "WHAT CAUSES WIND?" hope it helps :-) Adra :-)link : http://answers.yahoo.com/question/index;_ylt=Aje52sVJ.isZgFGM.Drr3CYjzKIX;_ylv=3?qid=20070307160808AAtx4Do
Because of Geographical abnormalities i.e: Trees, mountains, Hills, etc. Also, if you read up on the theory of the butterfly effect, it only takes a small movement at a given point to make a huge change at further off point 'b'. Such as a stone dropped in a pond. Small ripples near the stone become huge as they move away. Simillarly, a birds wings flapping, acar moving, a person waving his hand, a plane flying..all these magnify and cause disturbances in the atmosphere, which in turn force the breeze to change paths continually. Besides, wind rushes to points of low pressure, which also affect direction as low pressure points keep changing location.
because of the polar force that came from the north and south pole... the north has an downward force while south exerts an upward force therefore the movement of air become east to west.
The rotation of the earth curves them to the left and right

We name winds from the direction they come from. So north winds come from the north. East winds come from the east, and blow west. Winds can come out of any direction. The direction the winds come out of the most often depends on where you live.
It generally blows at the eastern part of the United States.
FROM the north. Winds take their names from their origin.

Global winds blow North to South
Planetary winds are any winds that occur because of solar radiation. They are in direct correlation to the rotation of the earth. Planetary winds do not blow directly north or south.

From North to South.
North of the 30th parallel, prevailing winds blow from the south-west. South of the 30th parallel, prevailing winds blow from the north-east.

South winds come from the south, or in other words, they blow in a direction from south to north.

No. In the Northern Hemisphere, the trade winds blow Northeast and in the Southern Hemisphere they blow Southeast
