Question

Among the following places, which one receives the comparatively lowest average monsoon rainfall from June to September?
A. Eastern Uttar Pradesh
B. Southern West Bengal
C. Western Uttar Pradesh
D. All receive almost the same rainfall

Answer 1

Hint: The period between June to September marks the duration of monsoon in India. Along the Ganga plains from east to west, the rainfall generally decreases. In the southern mountain ranges, the Western Ghats receive a very high level of rainfall.

Complete step-by-step answer:
Monsoons are marked by pressure differences between sea and land. Monsoon brings seasonal winds and rains. The monsoon makes up for $95%$ of rainfall in India. The North-western region of India receives considerable rainfall during the winter months. This is because of westerly disturbances and not because of monsoon. The retreating effect of the monsoon has been observed more in Tamil Nadu. The mango showers or the pre-monsoon showers predominantly prevail in West Bengal and Assam. A large part of India experiences tropical monsoon. The southwest monsoons are responsible for controlling the Agriculture of India. The main heavy pours are seen in the South-west monsoon period. 5 major rainfall regions can be divided based on the amount of rainfall received.
The very low rainfall regions are those that receive less than 30 cm of rainfall annually. The regions included in this category are the Karakoram ranges, northern Kashmir, western Kutch, and Rajasthan. The second category is for low rainfall regions. These are the Zaskar range, parts of Punjab and Haryana, central Rajasthan, Western Gujarat, and rain-shadow regions of the Western Ghats. They receive rainfall about 30 cm to 60 cm annually. The third category is moderate rainfall regions including the greatest parts of India. The rainfall is about 60 cm to 100 cm annually. The fourth one is heavy rainfall regions which receive about 100 to 200 cm of rainfall annually. These regions are the Western Ghats, Eastern Coastal belt, foothills of the Himalayas, and a part of North-East India. The last category is very high rainfall regions that are the Western side of the Western Ghats, Meghalaya plateau, Andaman and the Nicobar Islands.
From the above discussion, we can conclude that the rainfall decreases along the east to west regions of Ganga. Thus, the Western UP or Uttar Pradesh receives the minimum average rainfall among the given options.

Hence, option (C) is the correct answer.

Note: The Mawsynram in the Meghalayan plateau is the region which receives the maximum annual rainfall in the world. The special features of the Indian monsoon are that it is a unique weather phenomenon that shows the seasonal reversal of winds. The monsoon starts suddenly which is the sudden onset of rain.
