Question

Which of the following is the major reason for the global atmosphere pressure distribution?

(a) Convective air flow

(b) Conductive air flow

(c) Radiation air flow

(d) Conductive and radiation air flow

I have been asked this question by my school teacher while I was bunking the class.

This interesting question is from Characteristics of Atmosphere topic in section Atmosphere and Air Data Measurement of Aircraft Performance

Answer 1

Right option is (a) Convective air flow

Explanation: The convective air flow is the major reason for the global atmosphere pressure distribution. The Coriolis forces cause the air flow to swirl and create a series of convectional current cells which results in the general pattern of high and low pressure region over the surface of the earth.
