Study Notes

Indian Climate

  • Type of Climate: India has a tropical monsoon climate.
  • Factors Affecting Type of Climate:
    • Himalayas
    • Varied Relief
    • Distance from sea/ocean
    • Altitude

Monsoon Rainfall

  • Characteristics:
    • Reversal of wind system
    • Uneven distribution of rainfall over the year
    • Heavy rainfall in specific regions
  • Definition: The word Monsoon originates from the Arabic, meaning seasonal wind, often referring to the wind reversal.
  • Highest Rainfall Locations: Cherrapunji and Mawsynram (Meghalaya) receive the most rainfall.
  • Rainfall Distribution: Uneven, with some areas in rain shadow.

Factors Affecting Climate

  • Distance from Sea: Proximity or distance to oceans moderates temperature.
  • Altitude: Elevation affects temperature; higher altitudes are cooler.
  • Example: Mumbai is warmer than Kanpur in December due to coastal influence, while a continental climate causes extreme fluctuations in Kanpur.

Specific Climate Impacts

  • Mumbai vs. Kanpur (December): Mumbai's coastal location results in a milder climate than Kanpur's continental climate.
  • Punjab Winter Rainfall: Weak temperate cyclones from the Mediterranean contribute to winter precipitation.
  • Indo-Gangetic Plain (December/January Rainfall): Western disturbances from West Asia bring winter rainfall.
  • Malabar vs. Tamil Nadu (July Rainfall): The Malabar coast is on the windward side of the Western Ghats, while Tamil Nadu is in a rain shadow.
  • Northern Plains Climate: Distance from the sea leads to a continental climate.
  • Central vs. Western Maharashtra Rainfall: Central Maharashtra is in a rain shadow region, and thus receives less rainfall.

Climate Data Analysis (Example)

  • Annual Rainfall Calculation: Annual rainfall can be calculated by summing up monthly rainfall.
  • Station Identification (Example): Coromandel Coast's moderate temperatures and winter rainfall are suggestive.
  • Heaviest Rainfall Season: Retreating Monsoon (October-November) period brings the most rainfall.

North vs. South Indian Climate

  • Latitudinal Differences: The north experiences more extreme temperatures than the south.
  • Sun's Position: The sun is more directly overhead in the southern part at least twice a year.

Water Bodies' Influence

  • Coastal Areas: Water bodies moderate temperatures in coastal regions, creating a more pleasant climate.

Jet Streams

  • Definition: Jet streams are fast-flowing winds in the upper atmosphere, influencing weather patterns.
  • Indian Climate Influence: Jet streams often steer weather systems across India, and affect monsoon rainfall.

El Niño's Impact

  • Climate Impact: El Niño impacts monsoons, leading to weak or altered rainfall patterns.

Northeast Monsoon

  • Direction: Blow from land to sea.
  • Time Period: December to February
  • Rainfall Influence: Eastern coast (Tamil Nadu) can receive some rainfall.

Local Winds

  • Kalbaisakhi: Pre-monsoon showers in West Bengal.
  • Loo: Summer winds in North India.
  • Mango Showers: Pre-monsoon showers in Kerala and other areas

Rain Shadow Effect

  • Definition: Areas on the leeward side of mountains receive less rainfall.
  • Examples: Pune receives less rainfall than Mumbai due to the Western Ghats.

Burst/Break of Monsoon

  • Burst of Monsoon: Sudden onset of rainfall.
  • Break of Monsoon: Period of lack of rainfall.

Winter Rainfall

  • Sources (Punjab, Western UP): Western Disturbances; Mediterranean origin.
  • Sources (Tamil Nadu): Northeast Monsoons

Himalayan Impact

  • Hot Season: Himalayas act as a barrier preventing cold air from Siberia.
  • Monsoon Season: Act as a barrier to monsoon winds, with windward side receiving more rainfall.

Regional Rainfall Variations

  • Uneven Distribution: Many factors contribute to uneven rainfall across India, including relief and distance to ocean.

Benefit of Local Winds

  • Kerala: Brings rainfall necessary for mango ripening.
  • West Bengal: Brings rainfall beneficial for tea and rice crops.

Monsoons and Climate

  • Specific state analysis: Provide geographical reasons for different states receiving different amounts of rain at different times of the year

Tropical vs. Temperate Cyclones

  • Tropical Cyclones: Originate in the Bay of Bengal, associated with heavy rainfall.
  • Temperate Cyclones: Originate in West Asia, often bring weaker rainfall.

Retreating Monsoon

  • Time Period: October-November
  • Impact: weaker winds, change in pressure systems, sometimes rainfall (eastern India, depending on location and wind direction.)

Coastal/Continental Climates

  • Impact: Coastal regions tend to have more moderate temperatures compared to continental interiors.
