Geography
With the help of a suitable example explain how relief features affect the rainfall of a place.
Answer
Relief plays an important role in determining the rainfall of a place. Let us consider some examples,
- The Western Ghats receive heavy rainfall on the western side because they stand in the way of South West Monsoon winds which come from the Arabian Sea. On the other hand, the Deccan Plateau gets less rainfall as it lies in the rainshadow area of the Western Ghats.
- In Rajasthan, the Aravali Range is parallel to the direction of the South West Monsoon winds. So it is unable to stop the moisture laden winds. This makes Rajasthan a dry area.
- The southern hills of Assam get heavy rainfall but the northern ones do not. This is because the southern hills force the moisture laden winds to shed their moisture before they proceed northwards.
