i. Which pressure belt is mainly found in the Tropics? ii. With which pressure belt are the polar winds associated?

Question

Observe the diagram Fig. (a) and (b) carefully and answer the following questions:

i. Which pressure belt is mainly found in the Tropics?

ii. With which pressure belt are the polar winds associated? In which temperature zone are they observed?

iii. What could be the reason behind a low pressure belt in the Tropics?

iv. With which pressure belts are the winds in the Temperate zone associated?

v. Write the latitudinal extent of the low pressure belts.

Answer 1

i. Equatorial low pressure belt is mainly found in the tropics.

ii. The polar winds are associated with polar high pressure belt and sub polar low pressure belt. It is observed in the frigid zone.

iii. Low pressure belt is formed in the tropics because the temperature is high.

iv. The winds in temperate zone are associated with mid latitudinal high pressure belt.

v. The latitudinal extent of Equatorial low pressure belt is between 50°N & 50°S parallel & the latitudinal extent of the sub polar low pressure belt is between 55° & 65° parallel in both the hemispheres.
