Cloudburst

Sudden downpour in small area above 10cm in 1 hour in 100sq km area
Formation - warm airs puch monsoon clouds towards hills
Cloudbursts risk mostly in hills, sometimes cause destruction of life and liberty
Predictability - no satisfactory technique, precise techniques very expensive

Cyclone

Destruction due to accompanying destructive wind, storm surges, torrential rainfall
13 states UT are C prone, AP, Odisha, TN, Guj are highly prone
IMD nodal centre for warning, INSAT satellites used

Mitigation

Efficient forecast, rapid dissemination of warning, cyclone shelters
Coastal Belt plantation, Hazard mapping through meteorological records, land use control,
engineered structures - construct stilts on earth mound row of planted trees, buildings be water resistant, protect river embankments, strong halls to community shelter
Flood management, improve vegetation cover, coastal shelterbelt plantation

National Cyclone risk Mitigation Project NCRMP in Vulnerable States

4 components are A - last mile connectivity
B - Structural Non Structural measures
C - Technical assistance for risk mitigation
D - Project Mgt and implementation support

Challenges

lack of adequate response, planning, coordination, communication infra lack, end facilities
