Question Q.14Enumerate, RecommendGS1GS1
Enumerate the reasons behind rising intensity and frequency of cyclones in the Arabian Sea in recent years. Giving special reference to NDMA guidelines, recommend measures to check the adverse impacts of cyclones. (15 marks, 250 words)
Introduction
The Arabian sea has been experiencing increasing number of cyclones, 57% of which are severe as compared to 34% of those in the Bay of Bengal.

Main Body
Reasons behind rising intensity & frequency of cyclones:
1Rising sea surface temperatures which provide moisture to the cyclone (due to global warming). Ex - IITM estimated that temperatures in Arabian sea have risen by 1.2 to 1.4°C
2Madden Julian Oscillation which redirect cyclone genesis to the
Arabian sea due to its easterly flow.
3Shifting of cyclones from Bay of Bengal to Arabian sea due to wind direction (High level easterlies) Ex - cyclone Okhi.
4Indian ocean dipole's strengthening which creates favourable conditions for cyclone genesis.
Measures to check adverse impact of cyclones according to NDMA:
1Establishing a robust early warning system
2Setting up of National Disaster Communication Infrastructure (NDCI) for better communication to SDMA & DDMA.
3Establishing structural cyclone resilient infrastructure like cyclone shelters.
4Implementation of National Cyclone Risk Mitigation Project.
5Set up National Cyclone Disaster Risk Management Institute.
Other measures: learning from global best practices, training & mock drills, raising awareness, better coordination between departments & states.
