More cyclones in BoB than Arabian Sea
1Trough like shaped of BoB
2lack of Barriers between BoB & Pacific Ocean → winds from Pacific come directly giving necessary inputs for cyclone formation.
3High sea surface temperature is fulfills condition for 26°C temperature required for cyclogenesis
4River intermixing: Ganges etc. However, today Arabian Sea is also witnessing high frequency (eg cyclone Odhi, Taukbae) because of global warming etc.
Reasons for decrease in cyclones during SW Monsoon:
1IMD: [Global warming] has caused decreased cyclones during SW Monsoon
2% decrease of moisture in Arabian Sea.
