La Niña conditions have finally surfaced in the Pacific Ocean.
Below average sea surface temperatures reflected along the central and eastern Pacific Ocean.
La Niña is a phase and known as the El Niño Southern Oscillation (ENSO).
This climate phenomenon is characterised by changes in sea temperatures along the central and eastern tropical Pacific Ocean, accompanied with fluctuations in the atmosphere overhead.
ENSO influences, alters, and interferes with the global atmospheric circulation, which, in turn, influences the weather worldwide.
ENSO has three phases – warm (El Niño), cool (La Niña), and neutral — which occur in irregular cycles of two to seven years.
La Niña last occurred in 2020-2023, and El Niño in 2023-24.
