Question

(a) In which direction does wind blow between the equator and latitude 30°N? Why?
(b) Why does the wind swerve to one side instead of blowing straight?

Answer 1

a) The wind between the equator and latitude 30°N blows from latitude 30^o N towards the equator. As the regions close to the equator get maximum heat from the sun, the air near the earth's surface becomes warm and rises, producing a low pressure region. Cooler air from either side of the equator upto latitude 30^o rushes in to occupy the vacant place.

b) The wind swerves to one side instead of blowing straight because of the rotation of the earth on its axis. The rotation causes the wind in the northern hemisphere to swerve to its right and the wind in the southern hemisphere to swerve to its left.
