Key Topics to Revise

1

Factors Affecting Indian Climate

  • Location: India lies between 8°4' and 37°6' N latitude with Tropic of Cancer (23½°N) passing through the center
  • Distance from sea: Southern India is surrounded by water bodies on three sides, creating moderate climate
  • Altitude: Temperature decreases with height - hill stations like Shimla are cooler than plains
2

Mechanism of Monsoon

  • Summer heating creates low pressure over North Indian plains (monsoonal trough)
  • High pressure develops over Indian Ocean due to cooler temperatures
  • Pressure difference causes winds to blow from sea to land
3

Cycle of Seasons

  • Cold Weather Season (Dec-Feb): Clear skies, low temperatures, North-East trade winds
  • Hot Weather Season (Mar-May): High temperatures, 'Loo' winds, dust storms, Kaal Baisakhi
  • Advancing SW Monsoon (Jun-Sep): Heavy rainfall, 80-90% of annual rainfall
4

Distribution of Rainfall

  • Heavy rainfall (>200cm): Western coast, Sub-Himalayas, Meghalaya hills
  • Moderate rainfall (100-200cm): Parts of Western Ghats, West Bengal, Odisha
