Chapter 4: Climate of India
Introduction
India’s climate is diverse and influenced by various geographical and atmospheric factors. This chapter explores the climatic conditions that shape India, seasonal changes, and the monsoon's impact on the country’s life and culture.
Key Topics Covered
1. What is Climate?
Definition: Difference between climate and weather
Elements of Climate: Temperature, pressure, wind, humidity, and precipitation
2. Factors Affecting India’s Climate
Latitude and its impact on temperature
Altitude: Variations due to elevation
Pressure and Winds: Global air pressure belts affecting India
Distance from the Sea (Continentality): Influence on temperature and rainfall
Ocean Currents and Relief Features: Regional climate modifications
3. Climatic Controls
Influence of Himalayas and Tropic of Cancer
Seasonal Monsoon Patterns and how they impact India's climate zones
4. The Seasons of India
Winter (Cold Weather Season): Characteristics of the season, influence of northeast trade winds, and occurrence of winter rains
Summer (Hot Weather Season): Rising temperatures, hot dry winds called Loo, and pre-monsoon showers (Kaal Baisakhi)
Monsoon (Advancing Rainy Season): Onset and spread of the monsoon, varying rainfall across regions
Post-Monsoon Season (Retreating Monsoon): Characteristics of retreating monsoon, cyclones on the eastern coast, and "October heat"
