Factors responsible are:
1Rising temperature of the sea surface
Eg: Temperature of Arabian Sea has kept consistently above 26° during summer storms.
2Delaying onset of monsoon/ending, the presence of monsoon winds, which reduce vertical shear of depressions.
2Increasing pressure depression in Arabian Sea due to passage of increased temperature and also movement of depressions from Bay of Bengal.
3El Niño causing increased temperature and drought like situation in Western Pacific and consequently in Arabian Sea.
4Thermal pollution creating temperature rise and marine dead zones in the sea.
5Variation in delay in movement of Inter tropical convergence zone (ITCZ) causing rising temperature.
Hence the understanding of cyclone formation in Arabian Sea is an necessarily character resilience.
