What is La Niña 2022?

Cooler-than-average ocean temperatures indicated the presence of La Niña as of mid-May 2022. A typical La Niña will develop in late summer or fall, peak in the winter, then weaken in spring. But this spring, it’s gaining a bit of strength.

What is El Niño Lanino?

El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas. These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO).

When’s the next El Niño?

The probability for ENSO-neutral conditions is estimated at around 35% during March-May season, and the chance of El Niño developing is near-zero. The probability for a transition from La Niña to ENSO-neutral condition to occur during April-June 2022 is estimated to be about 50-60%.

Are we in El Niño now?

An El Nino is currently more likely in late 2022 and especially during the next winter season than an extended La Nina. So it’s time we look at how they actually differ from each other, both in the Ocean and in the Atmosphere.

What is El Niño Modoki?

El Niño Modoki is a coupled ocean-atmosphere phenomenon in the tropical Pacific. It is different from another coupled phenomenon in the tropical Pacific namely, El Niño. Conventional El Niño is characterized by strong anomalous warming in the eastern equatorial Pacific.

How long do La Ninas last?

El Ninos and La Ninas are actually quite common. They occur in a cycle that ranges from two to eight years. The former is slightly more frequent. Events usually last nine to 12 months but some, particularly La Ninas, can linger for two years in a row.

What is La Nina weather?

La Nina refers to the periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific. Typically, La Nina events occur every 3 to 5 years or so, but on occasion can occur over successive years. La Nina represents the cool phase of the El Nino/Southern Oscillation (ENSO) cycle.
