Consider the following statements. No cyclones in the Arabian Sea have...
Statement 1 is incorrect.
Some cyclones in the Arabian Sea have formed during the onset phase of the Indian Summer Monsoon.
Such a situation arose in 1984, 1985, 1987, 1988, 1989, 1992, 1994, 1996, 1998, 2001, 2007, 2010, 2011, 2014, 2015, 2018 and 2019 between 1979 and 2019. This is 17 years out of 41, showed the paper.
About 70 per cent of tropical cyclones and 90 per cent of the very severe and super cyclones over the Arabian Sea strike during May, June and November.
Cyclones and the monsoon impact each other. “A cyclone cannot form if we have a strong monsoon.
A weak onset of monsoon results in the formation of a cyclone.
The reason for the weak onset is not clear. It could be El Nino, the warm phase of a recurring climate pattern across the tropical Pacific. Indian Ocean warming due to climate change could also be playing a role.
