Introduction

Arabian Bay of Bengal has been harbour of cyclones but in recent years cyclone frequency in Arabian sea has also increased.

Main Body

[Reasons]

1climate change induced uncertainties

(a) El-Nino & La Nina patterns

2Indian Ocean dipole impact
3Low pressure conditions due to risen temperature (11°C already scaaling - IPCC)
4Local heating conditions also increases frequency.
5Changes in atmospheric circulations primary & secondary circulation (eg Trade winds)

All these require multidimensional measures to check adverse impact —

1[NDMA guidelines]

(a) Cyclone Risk Mitigation Plan

at state, national & local level.

2Cyclone shelters for relief & recovery.
3Early Warning systems for quick response.
2[Mitigation measures]

(a) Structural - conducting cyclone walls to minimise impact - Bioshields - Mangroves

2[Non-structural measures]

(a) Color-coded warnings (IMD)

(b) State-Wide Area Network (SWAN)

(c) Integrating cyclone management planning in state & local body budget.

(d) Constituting Mitigation fund (ISt Financial Commission)

Conclusion

India with 10% world cyclone is highly prone due to 5100km/1512kms coastline vulnerable to cyclones. This requires implementation of above measures to ensure EDG 13 (climate action), 14 (life below water) & 15 (life on land) by 2030.
