5. The Southern Oscillation refers to the atmospheric component of the ENSO system, involving changes in air pressure patterns between the eastern and western Pacific Ocean.
6. La Niña is the opposite phase of ENSO, characterized by the cooling of surface waters in the equatorial Pacific Ocean.
7. La Niña events typically follow El Niño events and can also have significant impacts on global weather patterns.
8. During La Niña, there is often a higher likelihood of drought conditions in some regions and increased hurricane activity in the Atlantic Ocean.
9. The ENSO phenomenon has important implications for agriculture, fisheries, and natural ecosystems around the world.
10. Scientists monitor and study ENSO to improve climate predictions and better understand its impacts on global weather patterns.

The periodic warming and cooling of surface waters in the equatorial Pacific Ocean — a phenomenon described as El Niño Southern Oscillations, or ENSO — is known to trigger widespread changes in atmospheric conditions, and has a major influence on global weather patterns, including the Indian monsoon. La Niña refers to the ENSO phase in which sea-surface temperatures are cooler than normal. The warmer phase is known as El Niño. A result of interactions between ocean and wind systems, El Niño and La Niña have almost opposite impacts on weather events.
