Cyclone Remal has brought heavy, incessant rain to Manipur. Manipur battles heavy rains, After causing widespread damage in Bangladesh and West Bengal.
About Cyclone
Cyclones are among the most devastating natural disasters, causing extensive damage to infrastructure economic and human live. cyclone is a rapidly rotating storm system characterized by a low-pressure center and strong winds, typically forming over warm ocean waters.
Conditions of Formation of Cyclone
The process starts with the surface temperature of the sea being warm, typically above 26.5°C . This warm water provides the necessary heat and moisture to the air above. As the warm, moist air rises from the sea surface, it cools and condenses to form clouds. This process of condensation releases latent heat, which warms the surrounding air, causing it to rise further. The rising warm air creates a low-pressure area at the center on surface of the sea. Air from surrounding areas with higher pressure moves towards this low-pressure area, causing winds to converge. Due to the rotation of the Earth, the Coriolis effect causes the moving air to start rotating. In the Northern Hemisphere, this rotation is counter clockwise while in Southern Hemisphere it is clockwise. As the air continues to rise and more warm, moist air is drawn in from the sea surface, the system starts to organize and develop a more defined cyclonic circulation. When the wind speed reaches 34 knots (63 kilometres per hour), the system is classified as a tropical cyclone. Further intensification can lead to it becoming a severe cyclonic storm or even a super cyclonic storm. The cyclone moves with prevailing winds, which in the Bay of Bengal usually guide it towards the coasts of India, Bangladesh, or Myanmar. When it makes landfall, it can cause significant damage due to high winds, heavy rainfall, and storm surges. After reaching the land area Cyclones usually weaken because they are no longer being “fed” by the energy from the warm ocean waters, and the cyclone dies.
