Study Notes
Climatic Controls of India
- Six major factors influence India's climate: latitude, altitude, pressure and wind system, distance from the sea (continentality), ocean currents, and relief features.
- Latitude: India lies between 8°4’ N and 37°6’ N, resulting in a diverse climate.
- Altitude: The Himalayas, averaging 6,000 meters, act as a barrier against cold winds from Central Asia.
- Pressure and Wind System: A high-pressure area forms north of the Himalayas in winter, leading to dry, cold winds blowing towards the south.
- Distance from Sea (Continentality): The presence of the Indian Ocean and Arabian Sea influences India's climate, leading to significant rainfall during the monsoon season.
- Ocean Currents: Ocean currents play a role in influencing temperature and rainfall patterns.
- Relief Features: The Himalayas, the Deccan Plateau, and the Ghats impact rainfall distribution and air circulation.
Monsoon and its Impact
- India experiences distinct monsoon seasons, with the south-west monsoon bringing heavy rainfall from June to September.
- The retreating monsoon from October to November brings clear skies and an increase in temperature, often referred to as "October heat".
- Rainfall variability is significant, leading to drought-prone areas in western Rajasthan, Gujarat, and the leeward side of the Western Ghats.
- Areas with heavy rainfall are prone to floods.
Key Geographic Features
- The Tropic of Cancer passes through India, dividing the country into tropical and subtropical regions.
- The Himalayas play a vital role in blocking cold winds, contributing to the generally warm climate of northern India.
- Mawsynram in Meghalaya receives the highest average rainfall in the world due to the monsoon.
- The Thar Desert in Rajasthan is a region of low precipitation.
- The Ganga valley experiences decreasing rainfall from east to west.
