Main Body

1eye → eye wall low pressure
What is a cyclone?(2) low pressure cloud system guided by latent heat of vaporisation

Mostly, (?) Tropical cyclone + requires orrolis force, Sea Surface October temperature > 27°C sometime in May

Factors responsible for rise in Arabian Sea

1Rise of sea surface temperature due to climate change
2High concentration of pollutants (West coast industrialised) → increase overall heat
3Favourable wind shear in Arabian Sea
4High building up of latent heat of vaporisation
5Shifting patterns of ITCZ → creates low pressure systems along with favourable easterly force
6Impacted by heating patterns in West Asia → creates pressure differential.
(i) Increasing cyclonesearlier limited to Bay of Bengal
(ii) Role of monsoon windsbrings cyclones to Arabian Seabecause seas

(iii) High impact due to coastal dominance (eg Cyclone Tauktae)

Cyclonic activities create devastating impact and cause disaster wish. However cyclones in Arabian Sea have lower intensity, due to low preparedness, their impact is magnified

Conclusion

Cyclonic activities create devastating impact and cause disaster. However cyclones in Arabian Sea have lower intensity; due to low preparedness, their impact is magnified.
