climate of india section 2 MCQ Questions & Answers Detailed Explanation

Answer: (a)

According to the thermal theory, during the hot subtropical summers, the massive landmass of the Indian Peninsula heats up at a different rate than the surrounding seas, resulting in a pressure gradient from south to north.

This causes the flow of moisture-laden winds from sea to land. On reaching land, these winds rise because of the geographical relief, cooling adiabatically and leading to Orographic rains, better known as the southwest monsoon.

Answer: (a)

The western side of the Western Ghats rise majestically to over 2500 meters above mean sea level to capture the Arabian sea branch of moisture-laden southwest monsoon winds.

The location of these mountain ranges is such that the South-West Monsoon that break over the southernmost tip of the peninsula during the last week of May, block the winds and they steadily rise against the mountain to condense rapidly and give copious rains on the western side.

Consequently, the eastern side is typically known as the rain shadow region.

Answer: (d)

Often during early summer, dusty squalls followed by spells of thunderstorm and heavy rains lash Assam and West Bengal, bringing relief from the humid heat.

These thunderstorms are convective in nature and are locally known as Kal Baisakhi or calamity of the month of Baisakh.

Answer: (c)

A Western Disturbance is an extratropical storm originating in the Mediterranean region that brings sudden rain to the northwestern parts of the Indian subcontinent during the winter season.

It is a non-monsoonal precipitation pattern driven by the westerlies. Western Disturbances are important for the development of the Rabi crop (wheat).
