Main Body
Ideal conditions required:
Sea surface temp ~27°C or above
Large area of low salinity
Low wind shear
Upper air divergence
Existence of low pressure region
Factors for increased activity over Arabian sea
1Early withdrawal of monsoon reduce Vertical wind shear
2Rising sea surface temperature due to climate change
3Increased glacial melt of rain providing greater amount of fresh water
4Presence of Low pressure trough from bay of bengal
5Greater summer of shade winter enhance cyclone season in October-November
6Weakening tropical Jet stream enome conditions for cyclones.
