🔆 Koeppen’s Climatic Classification of India
📍 Key Concepts
✅ Developed by Wladimir Koeppen — based on annual mean temperature and precipitation
✅ Links vegetation distribution with climate types
✅ Uses letter codes to classify major climate zones based on seasonality
📍 Major Climatic Types in India
✅ (Am) Monsoon with short dry season – West coast (e.g., Goa)
✅ (As) Monsoon with dry summer – Coromandel coast
✅ (Aw) Tropical Savanna – Most of Peninsular India
✅ (BShw) Semi-arid Steppe – Interior Deccan, Gujarat, Rajasthan, Punjab, J&K
✅ (BWhw) Hot Desert – West Rajasthan only
✅ (Cwg) Monsoon with dry winters – Northern Plains
✅ (Dfc) Cold-humid winter with short summer – Northeast India
✅ (E) Polar Climate – Upper Himalayas
✅ (ET) Tundra Climate – Higher Himalayan ranges, Ladakh
📍 Utility of the Classification
✅ Helps in agro-climatic zoning, crop selection, water planning
✅ Useful for disaster risk reduction, ecological studies, and climate adaptation policies
