1. Why in News?

• The recent unseasonal rainfall in northern India was caused by Western Disturbances.

• The possible emergence of El Niño conditions has raised concerns regarding weaker monsoon rainfall and severe heatwaves during summer.

• The increasing frequency of extreme weather events has made climate terms such as ENSO, heatwaves, and apparent temperature important for understanding India’s climate system.

2. The El Niño Southern Oscillation (ENSO) and Its Impacts

The Meaning of ENSO

• The El Niño Southern Oscillation (ENSO) is a large-scale climatic phenomenon involving fluctuations in ocean temperatures and atmospheric pressure over the Pacific Ocean.

• The ENSO system consists of three phases: El Niño, La Niña, and Neutral conditions.

The El Niño Phase

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

• The weakened trade winds during El Niño disrupt global atmospheric circulation.

The Impacts of El Niño on India

• The El Niño conditions generally weaken the Indian summer monsoon.

• The reduced monsoon rainfall may lead to drought-like situations and agricultural stress.

• The El Niño events also intensify heatwaves and increase summer temperatures across India.

The La Niña Phase

• The La Niña phase refers to the abnormal cooling of sea surface temperatures in the eastern Pacific Ocean.

• The stronger trade winds push warm waters westward toward Asia.

The Impacts of La Niña on India

• The La Niña conditions generally strengthen the Indian monsoon.

• The excessive rainfall during La Niña may increase the risks of floods and extreme precipitation events.

3. The Western Disturbances and Their Importance

The Meaning of Western Disturbances

• The Western Disturbances are extratropical storm systems originating in the Mediterranean region due to temperature contrasts between cold polar air masses and relatively warmer tropical air masses.

• The moisture-laden systems move eastward through West Asia, particularly Iran, Afghanistan, and Pakistan, before entering the Indian subcontinent.

• The Western Disturbances are non-monsoonal weather systems that primarily influence the winter climate of northwestern India.

• The systems derive moisture mainly from the Mediterranean Sea, Caspian Sea, Black Sea, and at times the Atlantic Ocean.

Formation and Movement of Western Disturbances

• The subtropical westerly jet stream acts as the main steering mechanism for Western Disturbances.

• The jet stream carries these low-pressure systems from west to east across the Eurasian region.

• The Himalayan mountain ranges obstruct the movement of these systems, forcing moisture condensation and precipitation over northern India.

• The interaction between cold air from higher latitudes and warmer tropical air intensifies rainfall and snowfall activities.

Characteristics of Western Disturbances

• The Western Disturbances mainly occur during the winter and early summer months between November and April.

• The systems are extratropical cyclones unlike tropical cyclones which form over warm oceans.

• The disturbances generally move from west to east under the influence of the subtropical westerly jet stream.

• The systems bring moderate to heavy rainfall over the northern plains and snowfall over the Himalayan regions.

• The Western Disturbances are usually associated with cloudy skies, thunderstorms, hailstorms, and sudden temperature changes.

• The repeated arrival of these systems during winter influences seasonal weather patterns across North India.

4. The Heatwaves and Apparent Temperature

• The India Meteorological Department (IMD) declares a heatwave when temperatures reach at least 40°C in plains and 30°C in hilly regions along with specified departure criteria from normal temperatures.

The Causes of Increasing Heatwaves

• The climate change and global warming are increasing the frequency and intensity of heatwaves.

• The urban heat island effect and declining green cover worsen heat stress in cities.

The Apparent Temperature or “Feels Like” Temperature

• The apparent temperature refers to the temperature perceived by the human body after accounting for humidity, wind speed, and atmospheric conditions.

• The high humidity reduces sweat evaporation and increases physiological stress during heatwaves.

5. The Significance and Way Forward

The Significance

• The climate phenomena such as ENSO and Western Disturbances strongly influence India’s agriculture, water resources, disaster management, and economy.

• The accurate climate forecasting helps governments prepare for droughts, floods, and heatwaves.

The Way Forward

• The climate-resilient agricultural practices should be strengthened to reduce vulnerability.

• The early warning systems and weather forecasting capabilities should be expanded.

• The urban planning should incorporate heat mitigation measures such as green cover and cool roofs.

• The disaster preparedness and water conservation measures should be improved.

6. The Conclusion

The increasing frequency of extreme climate events highlights the importance of understanding climatic systems such as ENSO, Western Disturbances, and heatwaves. These phenomena significantly influence India’s monsoon, agriculture, water security, and public health.

The scientific forecasting, climate adaptation policies, and sustainable environmental management will become essential for reducing the socio-economic impacts of climate variability in the future.
