24 words
Main Body
Factors causing increased cyclonic activity in Arabian sea: (1) Rising sea surface temperature due to global warming boosts cyclone formation (2) Per IPCC we have crossed 1.0°C above pre-industrial average (3) El Nino causing warming
Continued factors: (3) Strengthening of tropical depressions driving cyclones into India's west coast (4) Stability of cirrus over region weakening vertical wind shear (5) Subtropical jet stream results in increased low pressure regions in Arabian sea (6) Increase in climate variability due to climate change (7) Extreme confocal events in India up by 75%, since 1950 (CIMO)
Conclusion
This increased activity calls for enhanced preparedness by following NDMA guidelines & Early warning system of IMD
