El Niño-Southern Oscillation

El Niño-Southern Oscillation (ENSO) is climate phenomenon capable of changing the global atmospheric circulation, which in turn, influences temperature and precipitation across the globe. It is a single climate phenomenon having three states – El Niño, La Niña and the Neutral. While El Niño period is characterized by warming of sea surface in central and easter tropical Pacific Ocean, a La Niña event makes the temperature of the water in the eastern Pacific Ocean abnormally low.
A study has found that the increasing carbon emissions can weaken the intensity of the ENSO temperature cycle. The finding was made using the simulation in Aleph – one of South Korea’s fastest supercomputers.
