Why do most parts of India receive heavy rains only after a hot summer? Explain the reason in detail.
Dear Student,
The following points may help you to understand the mechanism of monsoon:
a. Rainfall in India emanate from two main sources: Bay of Bengal branch and Arabian sea branch.
b. Beginning from the month of june monsoon rains occur in intervals. The dry and wet spells of the monsoons vary in strength, frequency and duration causing floods and droughts at the same time in different regions. Advancing monsoon Begins from June till September
c. There is a complete change in weather is experienced after the inflow of the Southwest monsoons into India.
d. The monsoon rains occur in intervals. The dry and wet spells of the monsoons vary in strength, frequency and duration causing floods and droughts at the same time in different regions
e. Advancing monsoon is associated with the breaks in monsoon due to temperature variation and pressure gradient.
f. After hot summers, from the month of September, the low pressure begins to get weaker and is replaced by high pressure.
g. October to November is the period associated with retreating monsoon
h. Retreating monsoon is associated with the occurrence of cyclones originating from Andaman sea, causing cyclones in Bay of Bengal and rainfall in the eastern coast.
i. Then some regions experience winter rainfall, Tamil Nadu receives winter rainfall because of the retreating monsoon and the North-east Monsoon winds which pass over the Bay of Bengal, they get moisture and when they reach the Tamil Nadu coasts they cause rainfall there.
