Weather forecasting
Not met yet — counts as met once you answer a question on it.
Refers to the synoptic-scale tools and meteorological systems used in weather prediction — including cyclonic circulations, low-pressure troughs, upper-air wind patterns, Doppler radar networks, and the India Meteorological Department (IMD) alert colour-code system (yellow, orange, red) — with emphasis on how convergent circulation systems over coastal regions trigger convective precipitation and district-level advisories. The mechanism activates understanding of how IMD integrates numerical weather prediction models with real-time synoptic analysis to issue rainfall warnings, relevant to disaster preparedness under NDMA guidelines.
