    Study Notes

    Climate vs. Weather

    • Climate is the long-term average weather conditions of a region (more than 30 years)
    • Weather is the state of the atmosphere at a specific time and location

    Elements of Weather and Climate:

    • The elements of weather and climate are the same:
      • Temperature
      • Atmospheric pressure
      • Wind
      • Humidity
      • Precipitation

    India's Climate:

    • India's climate is characterized as the "monsoon" type
    • The word "monsoon" comes from the Arabic word "mausim" meaning "season"
    • Monsoon refers to the seasonal reversal of wind direction during a year

    Climate Controls:

    • Latitude
      • Due to the Earth's curvature, solar energy varies depending on latitude
      • Temperature generally decreases from the equator to the poles
    • Altitude
      • As altitude increases, air density decreases, causing a drop in temperature
      • Hills are cooler during summers
    • Pressure and Wind System
      • Latitude and altitude influence pressure and wind systems
      • Affects temperature and rainfall patterns
    • Distance from the Sea (Continentality)
      • The ocean moderates climate
      • As distance from the sea increases, moderation decreases, leading to extreme weather conditions
    • Ocean Currents
      • Currents affect coastal areas
      • Warm currents warm coastal regions, cold currents cool them
    • Relief Features
      • Mountains act as barriers to winds
      • High mountains cause precipitation when in the path of rain-bearing winds

    Factors Affecting India's Climate:

    • Latitude
      • The Tropic of Cancer divides India into two halves
      • The southern half is tropical, the northern half is subtropical
      • India's climate has characteristics of both tropical and subtropical climates
    • Altitude
      • Himalayan mountains in the north have an average height of 6,000 meters
      • The Himalayas prevent cold winds from Central Asia from entering India
      • India has relatively milder winters compared to Central Asia

    Atmospheric Conditions Affecting Indian Climate

    • Pressure and surface winds
    • Upper air circulation
    • Western cyclonic disturbances and tropical cyclones

    Regional Climate Variations in India:

    • Summer temperatures can reach 50°C in Rajasthan, while only 20°C in Pahalgam, Jammu and Kashmir
    • Winter temperatures in Drass, Jammu and Kashmir can reach -45°C, while Thiruvananthapuram may be 22°C
    • Snowfall occurs in the upper Himalayas, while the rest of India receives rainfall
    • Annual precipitation varies from over 400 cm in Meghalaya to less than 10 cm in Ladakh and western Rajasthan
    • Most of India receives rainfall from June to September, but the Tamil Nadu coast experiences heavy rainfall in October and November

    Coriolis Force:

    • An apparent force created by the Earth's rotation
    • Deflects winds to the right in the northern hemisphere and to the left in the southern hemisphere
    • Known as Ferrel's Law

    Why India is Not an Arid Land:

    • India lies in the region of northeasterly winds
    • These winds originate from the subtropical high-pressure belt of the northern hemisphere
    • They blow southwards and are deflected to the right due to the Coriolis force, moving towards the equatorial low-pressure area
    • While these winds carry little moisture, other factors counteract aridity
