This mind map explains the El Niño Southern Oscillation (ENSO) phenomenon, differentiating between its warm (El Niño) and cool (La Niña) phases, and detailing its significant global teleconnections, especially its impact on India's monsoon and weather patterns.

Changes in Pacific SST & Atmospheric Pressure
Southern Oscillation (Pressure Seesaw)
Warmer-than-average SST in East/Central Pacific
India Impact: Weakened Monsoon, Increased Drought Likelihood
Cooler-than-average SST in East/Central Pacific
India Impact: Above-average Monsoon Rainfall
Influences Weather Worldwide (Rainfall, Temp, Cyclones)
Occurs irregularly (2-7 years), lasts 9-12 months
Monitored by IMD, WMO for Forecasting

El Niño is characterized by warmer-than-average sea surface temperatures in the central and eastern equatorial Pacific, leading to a shift in rainfall patterns.
La Niña is characterized by cooler-than-average sea surface temperatures in the same region, often leading to opposite weather impacts.
The Southern Oscillation refers to the seesaw in atmospheric pressure between the eastern and western tropical Pacific.
During an El Niño event, India typically experiences a weakened monsoon and increased likelihood of droughts, as mentioned in the news.
During a La Niña event, India generally receives above-average monsoon rainfall.
ENSO events occur irregularly every 2 to 7 years and can last for 9-12 months, sometimes longer.
Has significant global teleconnections, influencing weather patterns across continents, including rainfall, temperatures, and cyclone activity.
Monitored by various international and national meteorological agencies like IMD for long-range forecasting.
The news states this trend is 'exacerbated by a strong El Niño effect', indicating its role in the dry December.
Impacts various sectors including agriculture, water resources, and disaster management.
