GEOGRAPHY

2. Understanding India’s Changing Weather Patterns

Context

• India is increasingly experiencing extreme weather events such as heatwaves, unseasonal rainfall, and rising humidity due to climatic phenomena like Western Disturbances, El Niño, and La Niña.
• These phenomena significantly influence India’s monsoon, agriculture, water resources, and public health.

What are Heat Waves?

• A heat wave refers to a period of abnormally high temperatures compared to the normal conditions of a region.

IMD Criteria for Heat Waves

According to the India Meteorological Department (IMD):

• Plains: Temperature above 40°C
• Coastal areas: Above 37°C
• Hilly regions: Above 30°C

Feels Like Temperature, Heat Index & Wind Chill

Feels Like Temperature

• Also called apparent temperature, it reflects how temperature is perceived by the human body after considering humidity and wind conditions.

Heat Index

• Combines actual temperature with relative humidity to estimate how hot conditions feel to humans.

Wind Chill Index

• Measures how cold weather feels when wind speed is combined with low temperatures.
• Wind removes the thin insulating layer of warm air around the body, making conditions feel colder.

Wet Bulb Temperature vs Dry Bulb Temperature

Wet Bulb Temperature

• Indicates the lowest temperature achievable through evaporation.
• Reflects the combined impact of heat and humidity.

Importance

• Human cooling depends on sweat evaporation.
• High humidity reduces evaporation efficiency, increasing heat stress risks.

Dry Bulb Temperature

• Refers to the actual air temperature measured using a standard thermometer.
• Does not consider atmospheric moisture.

What is a Western Disturbance (WD)?

• A Western Disturbance is an extra-tropical weather system that moves from west to east and brings rainfall and snowfall to northern India, especially during winter and early spring.

Origin and Formation of Western Disturbances

• They originate over regions such as:
  • Mediterranean Sea
  • Black Sea
  • Caspian Sea
• These systems form when cold polar air interacts with warm, moist air, creating low-pressure systems.
• They are carried eastward by the subtropical westerly jet stream.

Regions Affected in India

Western Disturbances mainly affect:

• Jammu & Kashmir
• Himachal Pradesh
• Uttarakhand
• Punjab
• Haryana
• Delhi
• Rajasthan
• Western Uttar Pradesh

Importance of Western Disturbances

Winter Rainfall

• Nearly 30% of annual winter precipitation in northwestern India is associated with Western Disturbances.

Agricultural Importance

• Vital for Rabi crops such as:
  • Wheat
  • Mustard
  • Barley
• Adequate rainfall improves soil moisture and crop productivity.

Ecological Importance

• Influences:
  • Himalayan glaciers
  • Snow storage
  • Biodiversity
  • River systems

What is ENSO (El Niño–Southern Oscillation)?

• ENSO is a periodic fluctuation in ocean temperatures and atmospheric pressure over the equatorial Pacific Ocean.

Major Phases

• El Niño
• La Niña
• ENSO strongly affects:
  • Indian monsoon
  • Cyclones
  • Floods and droughts
  • Global temperature patterns

What is El Niño?

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

Key Features

• Weakening of trade winds
• Rise in Pacific Ocean temperatures

Impact on India

• Usually associated with:
  • Higher temperatures
  • Weak monsoon rainfall
  • Drought-like conditions
• It reportedly contributed to a decline in foodgrain production during the 2023–24 crop year.

What is La Niña?

• La Niña is the opposite phase of El Niño and involves cooler-than-normal sea surface temperatures in the Pacific Ocean.

Key Features

• Stronger trade winds
• Movement of warm waters toward Asia

Impact

• Often linked with:
  • Higher rainfall in India
  • Floods in some regions
  • Wetter conditions in Australia

Impact on Indian Monsoon

During El Niño

• Weak monsoon circulation
• Reduced rainfall
• Agricultural stress and water shortages

During La Niña

• Increased rainfall in many parts of India
• Possibility of floods and extreme precipitation events

Way Forward

Strengthen Climate Forecasting

• Improve early warning systems and forecasting capabilities.

Promote Climate-Resilient Agriculture

• Encourage drought-resistant crops and efficient irrigation systems.

Water Conservation

• Enhance groundwater recharge and rainwater harvesting.

Climate-Sensitive Urban Planning

• Develop green infrastructure and heat mitigation measures in cities.

Public Awareness

• Increase awareness regarding heat stress, disaster preparedness, and climate adaptation.

Conclusion

• India’s changing weather patterns highlight the growing impact of climate variability and global warming on monsoon systems, agriculture, water security, and public health.
• Strengthening resilience through scientific forecasting, sustainable planning, and climate adaptation strategies will be crucial for managing future weather extremes.
