Lesson 3. Indian Monsoon: Mechanism, Seasons, and Climatic Regions

The pulsating rhythm of the Indian climate is governed by the monsoon. Understand its mechanism (differential heating, ITCZ shift, jet streams, El Niño/La Niña impact), its onset and progression, and break periods. Study the four traditional seasons and the spatial distribution of rainfall, leading to Koeppen’s climatic regions. NCERT Class IX & XI books explain basics clearly. For advanced understanding, refer to the “India Meteorological Department (IMD)” website for its annual forecasts and reports. Analyze recent trends of erratic monsoons, cloudbursts, and droughts covered in “The Hindu” or “Down To Earth.”
