How the exam will ask it
ପ୍ରିଲିମ୍ସ
- The north-east monsoon is also called the retreating monsoon season; it brings most of Tamil Nadu's annual rainfall.
- Unlike the south-west monsoon, the north-east monsoon winds blow from land to sea but pick up moisture over the Bay of Bengal before reaching the Coromandel Coast.
- The India Meteorological Department (IMD) issues the monsoon forecasts and heavy-rainfall warnings in India.
ମେନ୍ସ
GS-I (Indian climate, monsoon): the north-east monsoon makes the Tamil Nadu coast a winter-rainfall region, unlike most of India. Its vigour, with cyclonic systems over the Bay of Bengal, brings flood and urban-drainage risks. Better IMD forecasting, early warning, and flood-resilient urban planning are the way forward.
