Key Topics to Revise

1

1. Basic idea of monsoon climate

  • Monsoon means seasonal reversal of winds during the course of the year.
  • India’s climate changes with the season because winds, pressure, rainfall, and temperature all shift together.
  • Most rainfall in India comes in the summer season when moist south-west monsoon winds blow from sea to land.
2

2. Factors affecting India’s weather and climate

  • India lies roughly between 6° to 37°N latitudes, and the Tropic of Cancer passes through the middle of the country.
  • Southern India is closer to the Equator, so it remains warmer through the year.
  • Northern India lies in the warm temperate zone and has colder winters.

3. Theories and mechanism of monsoon

  • Sir Edmund Halley explained monsoon as the result of differential heating of land and sea.
  • Flohn criticized that view and explained monsoon through seasonal shift of pressure and wind belts.
  • The Inter-Tropical Convergence Zone is the zone near the equator where north-east trade winds and south-east trade winds meet.

4. Monsoon onset, advance, break, and retreat

  • The south-west monsoon sets in over the Kerala coast by 1 June.
  • It reaches Mumbai and Kolkata by 10-13 June.
  • It spreads over the entire sub-continent by 15 July.
