Episodes of El Niño and La Niña

La Niña
La Niña (/lə ˈniːnjə/ lə NEEN-yə, Spanish: [la ˈniɲa]; lit. 'The Girl') is an oceanic and atmospheric phenomenon that is the colder counterpart of El Niño, as part of the broader El Niño–Southern Oscillation (ENSO) climate pattern. › wiki › La_Niña
typically last nine to 12 months, but can sometimes last for years. El Niño and La Niña events occur every two to seven years, on average, but they don't occur on a regular schedule. Generally, El Niño occurs more frequently than La Niña.

How long does an El Niño last?

How long do El Niño and La Niña typically last? El Niñ o typically lasts 9-12 moñths while La Niñ a typically lasts 1-3 years.

How long is El Niño 2023?

We started noting the potential for a strong El Niño way back in April 2023, before El Niño had even arrived (that happened in June). Currently, forecasters estimate a greater than 55% chance that El Niño will remain above that threshold for strong through January–March 2024.

When was the longest El Niño?

The first half of the 1990s was unusual in that four years were all unusually warm in the equatorial Pacific. See The 1990-1995 El Niño-Southern Oscillation event: Longest on record.

How long does an El Niño episode last when does it generally start end how often do they occur?

El Niño occurs on average every two to seven years, and episodes typically last nine to 12 months. El Nino has its largest impacts during the winter. In the winter, El Niño typically brings milder weather to the northern parts of the United States and wetter conditions across the southern United States.

How does an El Niño end?

The warm water pool in the western (Asian) pacific drains eastward and toward the poles. This causes the thermocline in the western pacific to get closer to the surface, which in turn cools the surface temperature in the western pacific, ending the El Niño.

Does El Niño happen every 7 years?

El Nino is a natural climate phenomenon marked by warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean near the equator, which occurs on average every 2-7 years.

Will 2024 be hotter than 2023?

“We anticipate that 2024 is going to be an even warmer year because we're going to be starting off with that El Niño event,” said Gavin Schmidt, a Nasa climate scientist. “That will peak towards the end of this year, and how big that is is going to have a big impact on the following year's statistics.”

What is the El Niño forecast for 2023 2024?

Based on the latest forecasts, there is a greater than 55% chance of at least a "strong" El Niño (≥ 1.5°C in Niño-3.4 for a seasonal average) persisting through January-March 2024. There is a 35% chance of this event becoming "historically strong" (≥ 2.0°C) for the November-January season.

What El Niño will do to Earth in 2024?

The ongoing El Niño event is expected to last at least until April 2024, influencing weather patterns and contributing to a further spike in temperatures both on land and in the ocean, according to a new Update from the World Meteorological Organization.

Is El Niño wet or dry?

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. El Niño also has a strong effect on marine life off the Pacific coast.

What are 5 effects of El Niño?

What are the negative effects of El Nino? Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.

Is 2023 a La Niña year?

After three years of La Nina's influence on the tropics, conditions transitioned to El Niño in June 2023. The warmth shows up first in the far eastern tropical Pacific and steadily moves westward to engulf the Galápagos Islands and overtake the cool waters in the key El Niño-monitoring region.

Which is worse El Niño or La Niña?

In general, El Niño conditions lead to wetter, snowier conditions in Amarillo and cooler maximum temperatures during the winter. La Niña conditions lead to drier and warmer temperatures overall, with notable extreme cold spells. In stronger El Niño or La Niña episodes, these trends are even greater.

Is El Niño bad for hurricanes?

An ENSO-neutral or El Niño phase may hamper hurricane development in the Atlantic by increasing atmospheric stability and vertical wind shear, but thanks to the warm AMV phase, the increased ocean temperatures could offset those limiting factors.

Does El Niño mean colder winter?

One thing to note is that temperatures tend to be moderated during strong El Nino winters, owing to the Pacific-dominated flow. On average, strong El Nino winters have less very warm days (highs of 70 F or greater) as well as less very cold days (highs of 32 F or colder) when compared to the long- term normals.

Is 2023 going to be a hot summer?

The June-July-August (JJA) season for 2023 was the warmest on record globally by a large margin, with an average temperature of 16.77°C, 0.66°C above average. The European-average temperature for summer was 19.63°C, which at 0.83°C above average, was the fifth warmest for the summer season.

Why is summer 2023 so hot?

June, July, and August 2023 temperatures shattered global records for all three months. Summer's record heat was strongly influenced by human-caused climate change around the globe, according to Climate Central's Climate Shift Index (CSI).

Why is this summer so cold 2023?

The weather has been unseasonably cooler going into the summer of 2023 because of a combination of factors, including the development of El Niño, chilly water temperatures off the Pacific coast, and soggy soils in California.

Is El Niño getting stronger?

El Niño continues to strengthen in the tropical Pacific Ocean, which is likely to give global average temperatures a sizable boost going into next year. Why it matters: El Niño, a natural climate cycle, affects weather patterns around the world, bringing drought to some countries and flooding to others.

Does El Niño mean more snow?

At higher elevations, strong and moderate El Niño winters average more total snowfall compared to all winters, while at lower elevations, warmer temperatures mean more precipitation falls as rain.

What states are affected by El Niño?

Weather patterns throughout Alaska, Idaho, Oregon, and Washington are affected by El Niño, particularly in the winter season.

Will summer 2025 be hot?

It's becoming more likely that a key global temperature limit will be reached in one of the next five years. A major study says by 2025 there's a 40% chance of at least one year being 1.5C hotter than the pre-industrial level. That's the lower of two temperature limits set by the Paris Agreement on climate change.

What will happen to Earth in 2023?

But to breach the Paris agreement's limit, the heating must be sustained for many years. Earth is hurtling towards its average temperature rising by 1.5 °C above pre-industrial levels.

What is the hottest state 2023?

1. Florida: Sunshine and Sweltering Heat. Florida, the Sunshine State, tops the list of the hottest states in the US with an average temperature of 71.5°F (21.9°C). Known for its tropical climate, high humidity, and hot temperatures throughout the year, Florida is a hotspot for tourists.
