Cyclone Remal
Context
Cyclone Remal (meaning ‘sand’ in Arabic,) made landfall between West Bengal’s Sagar Island and Bangladesh’s Khepupara. It is the first pre-monsoon tropical cyclone in the Bay of Bengal this year.
Cyclones in India
- The Indian subcontinent, with a coastline of 7,516 km, is one of the worst-affected regions in the world for cyclones.
- India is exposed to nearly 10% of the world's tropical cyclones, most of which originate in the Bay of Bengal.
- Cyclones are atmospheric disturbances around a low-pressure area with fast and often destructive air circulation, violent storms, and heavy rainfall.
- In the Northern Hemisphere, air circulates inward anticlockwise, while in the Southern Hemisphere, it circulates clockwise. Reason- Coriolis force
- Eye: The centre of a cyclone is called the eye of the storm (calm area). It diameter varies from 10 to 30 km.
- Inside the cyclone eye, the temperature is greater than 28°C and the dewpoint is less than 0°C.
- Categories of Cyclones
- Category 1: Wind speed of 120-150 km/h, minimal damage capacity.
- Category 2: Wind speed of 150-180 km/h, moderate damage capacity.
- Category 3: Wind speed of 180-210 km/h, extensive damage capacity.
- Category 4: Wind speed of 210-250 km/h, extreme damage capacity.
- Category 5: Wind speed of 250 km/h and above, catastrophic damage capacity.
