Difference Between North-east and Retreating Monsoon:
The following are the points of difference between North-east and Retreating Monsoon.
The wind blowing from North-east direction in India from December to February is known by the name North-east Monsoon.
The South-west Monsoon winds start retreating in India from October and they retreat from the southern parts by the end of November. These retreating Monsoon winds are called the Retreating Monsoon.
During winter high-pressure region is established on the land in India. Hence they blow from land to sea.
The low-pressure region of north-west India shifts to the Bay of Bengal in November. Hence these winds blow from the North-west to the South-est towards the Bay of Bengal.
These winds blowing from land are cold and dry.
These winds are cool and moist due to the local influence. They retreat gradually from the mainland.
Generally, these Monsoon winds do not cause rains. But when they reach the eastern coasts of Tamil Nadu after crossing over the Bay of Bengal, they cause heavy rainfall there. This is the reason why the Tamil Nadu coast experiences rainfall during winter.
During the period of Retreating Monsoon, the Bay of Bengal witnessed the formation of tropical cyclones.
Barring the eastern coastal belt, the whole of India has clear skies, low temperatures and low humidity, gentle cold breeze and fine cold weather.
The cyclone intensifies the Retreating Monsoon winds. Hence they cause heavy downpour on the eastern coast of Orissa, Andhra Pradesh and Tamil Nadu.
