Question

Advancing monsoon and retreating monsoon??

Answer 1

Answer:

Advancing Monsoon : South West Monsoon winds blow over the warm oceans and thus bear moisture bringing abundant rainfall in India. The monsoon covers the entire country in about a month’s time. The arrival of the Monsoon winds brings a change in the weather of the country. Sometimes at the time of arrival, the rainfall increases suddenly which is commonly known as the burst of the Monsoons. The western slopes of the Western Ghats receive heavy rainfall from the monsoon winds. Sometimes, there are ‘brakes’ in the monsoon rainfall. Initially at some places, it rains only for few days. While it rains heavily in north eastern parts of the country, Kerala and on the western slopes of the Western Ghats, moderate rainfall is experienced in the south eastern parts of the country and the Indo Gangetic Plains. Scanty rainfall is experienced in western parts of Rajasthan, Punjab, Haryana and Gujarat.

Retreating Monsoon : During October and November, the South West monsoon winds become weaker and start retreating from the by clear skies and the increase in mercury northern plains. The retreat of monsoon is marked level. This increase in temperature is termed as ‘October heat’. At this time, the low pressure conditions shift to the Bay of Bengal giving rise to cyclonic depressions. These cyclonic depressions often results in the destruction of life and property generally on the eastern coast and the southern coast. Most of the rainfall of the Coromandel Coast is derived from depressions and cyclones.
