MAINS Current Affairs includes Early Onset of Southwest Monsoon & Hope India Continues to Develop Chabahar: Iran FM

GEOGRAPHY

1. Early Onset of Southwest Monsoon

Context: The India Meteorological Department (IMD) recently announced that the Southwest Monsoon is likely to reach Kerala earlier than its normal onset date of June 1.

Monsoon in India

• The term monsoon refers to the seasonal reversal of winds caused by differential heating and cooling of land and sea.
• Monsoon rainfall is central to India’s climate, agriculture, economy, and water security.

Major Monsoon Systems in India

1. Southwest Monsoon (June–September)

• Main rainy season in India.
• Contributes nearly 75% of annual rainfall.

2. Northeast Monsoon (October–December)

• Important mainly for:
  • Tamil Nadu
  • Coastal Andhra Pradesh
  • Southeast India

Importance of the Southwest Monsoon

Agricultural Importance

• Nearly 60% of Indian farmers depend on rainfall for irrigation and crop sowing.

Key Crops

• Rice
• Cotton
• Sugarcane
• Pulses

Economic Significance

• Monsoon influences:
  • GDP growth
  • Food production
  • Rural demand
  • Inflation

Water Security

• Recharges:
  • Rivers
  • Reservoirs
  • Groundwater aquifers
• Supports hydropower generation and drinking water supply.

Ecological Importance

• Sustains forests, wetlands, biodiversity, and overall hydrological balance.

Formation of the Southwest Monsoon

1. Differential Heating

• During summer, the Indian landmass heats up faster than surrounding oceans.
• This creates a low-pressure area over northwest India.

2. Shift of ITCZ

• The Inter Tropical Convergence Zone (ITCZ) shifts northward during summer.
• It attracts moisture-laden winds from the Indian Ocean toward India.

3. Cross-Equatorial Winds

• Southeast trade winds cross the Equator and get deflected due to the Coriolis force, becoming southwesterly winds.

4. Role of Tibetan Plateau & Jet Streams

• Heating of the Tibetan Plateau strengthens monsoon circulation.
• Changes in subtropical jet streams also influence monsoon intensity and onset.

Branches of the Southwest Monsoon

Arabian Sea Branch

• Strikes the Western Ghats first.
• Causes heavy rainfall along India’s western coast.
• Advances toward central and northern India.

Bay of Bengal Branch

• Moves toward northeast India and the Indo-Gangetic plains.
• Deflected westward by the Himalayas across northern India.

El Niño and Indian Monsoon

What is El Niño?

• El Niño refers to abnormal warming of sea surface temperatures in the equatorial Pacific Ocean.

Impact on Indian Monsoon

• Weakens monsoon circulation
• Often leads to below-normal rainfall in India

NOAA Forecast

• The National Oceanic and Atmospheric Administration (NOAA) estimated a high probability of El Niño development during May–July.

IMD Forecast

• IMD projected seasonal rainfall at nearly 92% of the Long Period Average (LPA), indicating below-normal rainfall conditions.

Risks Associated with Strong El Niño

A strong or “super” El Niño may lead to:

• Reduced agricultural productivity
• Drought-like conditions
• Groundwater depletion
• Reservoir stress
• Food inflation
• Rural distress
• Regions such as the Indo-Gangetic Plain are especially vulnerable because of long-term drying trends.

Significance of Early Monsoon Onset

Positive Impacts

• Early sowing of Kharif crops
• Better soil moisture availability
• Improved reservoir recharge
• Support for rural livelihoods

Possible Concerns

• Early onset does not always guarantee:
  • Uniform rainfall distribution
  • Normal monsoon performance
  • Adequate seasonal rainfall
• Breaks in monsoon or uneven distribution may still occur later.

Challenges Affecting Indian Monsoon

Climate Change

• Increasing frequency of:
  • Extreme rainfall events
  • Heatwaves
  • Erratic monsoon behaviour

Urbanisation & Land Use Changes

• Deforestation and urban expansion affect local rainfall patterns and water absorption.

Rising Ocean Temperatures

• Indian Ocean warming may alter monsoon circulation and intensity.

Way Forward

Improve Forecasting Systems

• Strengthen climate modelling and early warning systems.

Promote Climate-Resilient Agriculture

• Encourage drought-resistant crops and efficient irrigation practices.

Enhance Water Management

• Improve groundwater recharge, reservoir management, and rainwater harvesting.

Strengthen Disaster Preparedness

• Develop better flood and drought mitigation strategies.

Conclusion

• The Southwest Monsoon remains the backbone of India’s agriculture, economy, and water security.
• While an early onset may provide initial benefits, the overall distribution and intensity of rainfall are more important for long-term outcomes.
• Strengthening climate resilience, forecasting capacity, and sustainable water management will be essential in the face of increasing climate variability.
