Why are the deltas of the Krishna, Kaveri and Godavari frequently struck by cyclones?
Answer:
- The low pressure conditions over north-western India, get transferred to the Bay of Bengal by early November.
- This shift is associated with the occurrence of cyclonic depressions which originate over the Andaman Sea.
- These cyclones generally cross the eastern coasts of India and cause heavy and widespread rains.
- These tropical cyclones are often very destructive.
- The thickly populated deltas of the Godavari, the Krishna and the Kaveri are frequently struck by cyclones, which cause great damage to life and property.
- Sometimes, these cyclones arrive at the coasts of Odisha, W. Bengal and Bangladesh. The bulk of rainfall of the Coromandel coast is derived from depression and cyclones.
