उत्तर
- Mumbai (SouthWest Monsoon):
-
The Southwest Monsoon brings rain to Mumbai during the summer (June to September).
- Southwest Monsoon winds move from the Indian Ocean, bringing moist winds to India's western coast. Because Mumbai is located on the windward side of the Western Ghats, it experiences significant rain during this time.
-
- Chennai (Northeast Monsoon):
- The majority of Chennai's rainfall falls between October and December during the Northeast Monsoon (also known as the retreating monsoon).
- During this period, the winds shift direction and blow northeast, taking up moisture from the Bay of Bengal. This causes considerable rains in Chennai and other parts of Tamil Nadu.
