Main Body

Cyclones are intense low pressure zones, with high wind speeds & associated rainfall.

Rising intensity & frequency of cyclones in Arabian Sea — Bipolarity

1Increasing sea surface temperature in Arabian sea during global warming (rise of 1.5°C). Global temperature — 1.8°C.
2Rising temperature — increasing moisture holding capacity of air — higher intensity of convectional precipitation.
3Changing nature of upper atmosphere circulation (eg Jet streams)

Check adverse impacts of cyclones

NDMA guidelines

1Structural measures:

— embark walls to preserve ingress of storm surges

— Looky warning systems — better predictions

2Non structural measures:

— creation of temporary shelter, forecarte evacuation

— awareness on cyclone warnings & safety drills in vulnerable areas.

Cyclones as a hazard must be prevented to become major disasters.
