Q. Consider the following statements:

1. The variations in the atmospheric pressure closer to the surface of the earth decides the upper air circulation.
2. All of Western and Central Asia remains under the influence of easterly winds.

Which of the above is / are correct?
Answer: None of the above
Notes: The pattern of air circulation discussed above is witnessed only at the lower level of the atmosphere near the surface of the earth. Higher up in the lower troposphere, about three km above the surface of the earth, a different pattern of air circulation is observed. The variations in the atmospheric pressure closer to the surface of the earth have no role to play in the making of upper air circulation. All of Western and Central Asia remains under the influence of westerly winds along the altitude of 9-13 km from west to east.
