If you are someone who wants more or stronger ENSO events in the future, I have great news for you–research supports that. If you are someone who wants fewer or weaker ENSO events in the future, don’t worry–research supports that too.
The forecast models are largely in agreement that SSTs will continue to trend upward, with the majority of models indicating a Niño3.4 index value above 0.5°C by early summer. Forecast show the chance of El Niño increasing during the remainder of the year, exceeding 65% during the summer.
Though ENSO is a single climate phenomenon, it has three states, or phases, it can be in. The two opposite phases, “El Niño” and “La Niña,” require certain changes in both the ocean and the atmosphere because ENSO is a coupled climate phenomenon. “Neutral” is in the middle of the continuum.
