Topic – Part of static series under the heading – “pressure belts of the world”
5) Explain what causes the shifting of pressure belts and the impact it has on the climate of different regions of the world?(250 words).
Key demand of the question
The question expects us to describe what causes the shift of pressure belts with shift in position of the sun. Thereafter, it expects us to explain how the shifting pressure impacts the different climatic zones of the world such as Mediterranean climate etc
Structure of the answer
Introduction – Explain what these pressure belts are and what causes them to shift. In the absence of the revolution of the earth around the sun, the global pressure belts would have been permanent and stationary at their places but the relative position of the earth with the sun changes within a year due to earth’s revolution and thus the position of all the pressure belts except the polar high pressure belts changes with the northward and southward migration of the sun.
Body – Explain the impact that the shift in pressure belts has on Mediterranean type of climate, regions lying between 60°-70° latitudes are characterized by two types of winds in a year because of shifting of pressure and wind belts, Monsoon climate is the result of the shifting of pressure and wind belts. Explain the impact of shifting pressure belts on such types of cases in greater detail.
