Cyclones are intense circular storms that originate over warm tropical oceans and are characterized by low atmospheric pressure, high winds, and heavy rain. India, with its extensive coastline along the Arabian Sea and the Bay of Bengal, is particularly vulnerable to cyclones.
Cyclones form over warm ocean waters where the sea surface temperature exceeds 26°C (79°F). The warm, moist air rises, creating a low-pressure area. As the air rises and cools, it condenses to form clouds and rain, releasing latent heat that further strengthens the storm. The Coriolis effect causes the storm to rotate, leading to the formation of a cyclonic system.
Cyclones are categorized based on their wind speeds and intensity:
India’s coastline is prone to cyclones from both the Bay of Bengal and the Arabian Sea:
Cyclones can have devastating impacts, including:
India’s approach to cyclone management involves several key strategies:
Climate change is expected to influence the frequency and intensity of cyclones. Rising sea temperatures may lead to more intense cyclones, while changes in atmospheric patterns could alter their frequency and tracks. Understanding these changes is crucial for improving cyclone preparedness and adaptation strategies.
Cyclones are a major natural hazard for India, with significant impacts on human life, infrastructure, and the economy. Effective management and preparedness are essential to mitigate their effects. For UPSC aspirants, understanding the dynamics of cyclones, their impact, and the measures taken for management is crucial for comprehensive preparation in disaster management and environmental studies.

India’s coastline is vulnerable to cyclones from two primary sources:
Cyclones can cause:
India employs several strategies for cyclone management:
Climate change is expected to influence cyclones by potentially increasing their frequency and intensity. Rising sea temperatures may lead to more intense cyclones, while changes in atmospheric patterns could alter their frequency and tracks. Understanding these impacts is crucial for improving cyclone preparedness and adaptation strategies.
Cyclones are a significant natural hazard impacting human life, infrastructure, and the economy. For UPSC students, understanding cyclones is important for disaster management, environmental studies, and general knowledge. It helps in preparing for questions related to natural disasters, climate change, and environmental policies.
