Describe the various conditions of retreating monsoon season and distribution of rain.

Solution
The monsoon starts retreating in the months of October and November. In this way, the speed of low air pressure becomes slow and replaced by the higher air pressure. As a result of this, the monsoon starts going back. The access of monsoon also lessens due to gradual detereoration of power. Its influential area till then is seeped into Indian lands. The conditions of surface winds start reversing and monsoon shifts back from northern plains by October month every year.

Conditions of Season : In the month of October and November, the dry winter season starts replacing the rainy season. The sky becomes clear due to removal of monsoons and the temperature starts increasing. It is popularly called the ‘October heat’ or the humidity and heat of Kwar according to the Hindu theology.

The low air pressure of north-west India transfers to the Bay of Bengal in the month of November. During this period, Andaman sea again starts raising cyclones. The summer solstice cyclones are destructive in nature. These strike the deltas of the Godavari, Krishna, Mahanadi and Kaveri rivers of Peninsular India. Sometimes, these reach upto Sunderbans and Bangladesh also. Coromandel coast receives most rainfall due to these cyclones.
