Is 2021 an El Niño year?

National Meteorological and Hydrological Services will closely monitor changes in the state of El Niño/Southern Oscillation (ENSO) over the coming months and provide updated outlooks. In summary: The tropical Pacific has been ENSO-neutral since May 2021, based on both oceanic and atmospheric indicators.

What is modoki El Niño?

Definition: Modoki El Nino is different from traditional El Nino because the SST warming is largely in the central equatorial Pacific region instead of in the eastern equatorial Pacific region. The first recorded El Niño that originated in the central Pacific and moved toward the east was in 1986.

Does El Niño cause cold winter?

El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North.

What is a modoki event?

Modoki is Japanese for “same but different,” and this is indeed the case. El Nino Modoki events are a rarer subset of regular El Nino’s, and are marked by warming water in the Pacific, but not along the Equator. Instead, the warming is in the mid-Pacific and the warming is not as strong as in regular El Nino events.

Are we in an El Nino or La Niña?

As things stand with the El Niño-Southern Oscillation (ENSO), neutral conditions are currently present in the tropical Pacific and favored to last through the North American summer and into the fall.

Is El Nino wet or dry?

Weather typically differs markedly from north to south during an El Niño event (wet in south, dry in north) but also usually varies greatly within one region from event to event.

How do El Niño and El Nina affect climate?

El Niño and La Niña are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth every 3-7 years on average. By modifying the jet streams, El Niño and La Niña can affect temperature and precipitation across the United States and other parts of the world.

Does El Nino bring more snow?

Snowfall. During an El Niño, snowfall is greater than average across the southern Rockies and Sierra Nevada mountain range, and is well-below normal across the Upper Midwest and Great Lakes states.

What does El Nino mean for winter?

El Niño, which is a climate phenomenon characterized by unusually warm ocean temperatures in the central and eastern tropical Pacific Ocean, can influence the winter weather across the United States. On average, the stronger the El Niño episode, the warmer and wetter the winters have been.
