How does the earth rotation on its axis affect the global atmospheric air circulation ?

Question

How does global atmospheric air circulation created.
How the earth rotation on its axis affect the global air motion?
Where the air starts its motion and where it ends?

Answer 1

The earth's rotation causes the air to turn to the right in the northern hemisphere and to turn to the left in the southern hemisphere. This tendency is referred to as the Coriolis force or coriolis accelerations. Latitudinal temperature differences between the equator and poles are the cause of differences in air pressure and density which in turn cause winds but it is the coriolis force due to the earth's rotation that most affect circulation.

Answer 2

Interestingly, in the past century, sea levels have risen at about the same rate as they did between 1400-1850. Since there was no large scale industrial activity and thus no human-caused global warming before 1850, this should immediately lead us to question the hypothesis that global warming is causing sea levels to rise. Further, the climate warmed sharply between 1900-1940, and actually cooled between 1940-1975. The data show that the sea level rise *slowed* during the warming period and *speeded up* during the cooling period. What's the reason for this? A warmer climate leads to increased evaporation from oceans, and part of the evaporated water rains back as snow on the Antarctic and on Greenland, thereby effectively taking water out of the oceans. According to the article linked below, the real cause of rising sea levels appears to be the continued melting of the west antarctic ice sheet that has been going on ever since the end of the last ice age. Unless there's another ice age, we can expect sea levels to continue rising for the next 7000 years or so until the WAIS is gone. This melting has nothing to do with global warming, and there's really nothing we can do about it. The bottom line in all this is that the climate is a fiendishly complex thing, and the people who tout simple answers are more than likely incorrect.

Answer 3

Global Air Circulation

Answer 4

The Earth's atmosphere is put into motion because of the differential heating of the Earth surface.
Tropics receive more heat than the poles because:
Sun's rays are more perpendicular to the Earth and the cross-sectional area of Sun's rays striking the earth's surface is smaller at the equator. Therefore, the heating per square area is greater at the equator than at the poles.
The thickness of the atmosphere that the Sun's rays must past through is greater at the poles than at the equator. Therefore, more of the radiation is attenuated at the poles than at the equator.
