Page 14: Research news on el nino southern oscillation
El Niño–Southern Oscillation (ENSO) is a coupled ocean–atmosphere phenomenon in the tropical Pacific characterized by quasi-periodic fluctuations between warm (El Niño), cold (La Niña), and neutral phases. It arises from interactions among equatorial Pacific sea-surface temperatures, trade winds, and the Walker circulation, producing large-scale anomalies in convection, thermocline depth, and surface pressure, notably the Southern Oscillation index. ENSO modulates global atmospheric circulation, altering precipitation, temperature, and storm tracks on interannual timescales, and serves as a key source of seasonal-to-interannual climate variability and predictability in climate diagnostics and modeling.
Ocean mixing intensifies central Pacific ENSO via diabatic heating, study reveals
The El Niño and Southern Oscillation (ENSO) is one of the most influential interannual climate phenomena in the global ocean-atmospheric system, with profound impacts on weather patterns, particularly in the Asia-Pacific ...
