Question

Q.4. Season of Retreating Monsoon 1x3=3
The months of October and November are known for retreating monsoons. By the end of September, the
southwest monsoon becomes weak as the low pressure trough of the Ganga plain starts moving
southward in response to the southward march of the sun. The monsoon retreats from the western
Rajasthan by the first week of September. It withdraws from Rajasthan, Gujarat, Western Ganga plain
and the Central Highlands by the end of the month. By the beginning of October, the low pressure covers
northern parts of the Bay of Bengal and by early November, it moves. over Karnataka and Tamil Nadu.
By the middle of December, the centre of low pressure is completely removed from the Peninsula. The
retreating southwest monsoon season is marked by clear skies and rise in temperature. The land is still
moist. Owing to the conditions of high temperature and humidity, the weather becomes rather oppressive.
This is commonly known as the ‘October heat’. In the second half of October, the mercury begins to fall
rapidly, particularly in northern India. The weather in the retreating monsoon is dry in north India but it is
associated with rain in the eastern part of the Peninsula. Here, October and November are the rainiest
months of the year. The widespread rain in this season is associated with the passage of cyclonic
depressions which originate over the Andaman Sea and manage to cross the eastern coast of the southern
Peninsula.
