Study Notes

Climate of India

  • India's climate is described as monsoon type, primarily found in South and Southeast Asia.
  • Regional variations in climate exist despite a general pattern.
  • Key elements include temperature and rainfall, which vary regionally and seasonally.

Temperature Variations

  • Summer temperatures can reach 50°C in Rajasthan, while being much lower in other areas like Pahalgam (20°C).
  • Winter temperatures can drop to -45°C in Drass, while remaining warmer at Thiruvananthapuram (22°C).
  • Day-night temperature differences vary significantly; the Thar Desert experiences large fluctuations while the Andaman and Nicobar islands and Kerala have smaller differences.

Rainfall Variations

  • Precipitation varies significantly across the country.
  • High rainfall areas include Meghalaya (over 400 cm) and low rainfall areas include Ladakh and Western Rajasthan (under 10 cm).
  • Rainfall occurs mainly from June to September, but Tamil Nadu receives some rainfall outside this period.
  • Variations in precipitation include the form (snowfall in Himalayas, rain elsewhere), and seasonal distribution.

Climatic Controls

  • Latitude, altitude, pressure and wind patterns, distance from the sea (continentality), ocean currents, and relief features control a region's climate.
  • Latitude affects temperature gradients, decreasing from equator towards the poles.
  • Altitude leads to cooler temperatures at higher elevations.
  • Ocean proximity moderates temperatures in coastal regions.
  • Relief features (mountains) can act as barriers or cause precipitation.

Seasons

  • India has four main seasons:
    • Cold weather season (November-February): Cooler temperatures, particularly in the north. Light winds and clear skies.
    • Hot weather season (March-May): Shift of the sun's path north-wards, leading to high temperatures, especially in the northwest of the country.
    • Advancing monsoon season (June-September): The start of heavy rainfall, influenced by low-pressure conditions attracting moist winds.
    • Retreating monsoon season (October-November): Monsoon withdraws; changes from wet to drier conditions; "October heat" and potential for cyclonic activity.
