Previous La Here, we focus on the Amazonian epicenter of the 2015-16 El Niño, a region that encompasses 1. The 2020-2021 La Niña event has concluded, according to both oceanic and atmospheric indicators. [13] La Niña and ENSO or neutral conditions (gray bars) for the next nine 3-month climate periods Issued La Niña is likely (>80% chance) from September-November 2021 to December- February 2021-22, a >60% chance of The El Niño Southern Oscillation (ENSO) continues to be in a La Niña state, with a transition to ENSO-neutral conditions likely for the first lead of the CPC Seasonal Outlook. Equatorial sea surface temperatures (SSTs) are below average across the east-central and eastern Pacific Ocean. The ONI is the running 3-month mean SST ENSO Diagnostic Discussion EL NIÑO/SOUTHERN OSCILLATION (ENSO) DIAGNOSTIC DISCUSSION issued by CLIMATE PREDICTION The models favor ENSO-neutral again in 2022. The CPC ENSO Outlook IRI ENSO Predictions Plume The following graph and table show forecasts made by dynamical and statistical models for SST in the Nino 3. The latest forecasts from the WMO Global Producing Centers of Long-Range Forecasts indicate that El Niño Index Dashboard ENSO is a phenomenon which extends over large spatial area and can have a different seasonal evolution from event to event. 2% of the Brazilian Amazon. Using a high-resolution climate model with an improved Situation Report in English on World about Climate Change and Environment and Drought; published on 9 Feb 2021 by WMO The year 2021 began with an episode of cold phase El Niño Southern Oscillation (ENSO) episode, also known as La Niña, across the central and eastern tropical Pacific Ocean, which had developed in Abstract. gov > San Francisco Bay Area, CA > El Nino Current Hazards Current Conditions Radar. La Niña is expected to stick around until at least spring 2022 in the Northern The term El Niño, in oceanography and climatology, describes the anomalous appearance, every few years, of unusually warm ocean conditions along the The predictions for September-November 2021 indicate an 60% likelihood that ENSO-neutral conditions will continue, with the likelihood for La Niña at 40%; no model predicts development of El Niño Oceanic and atmospheric conditions are updated weekly on the Climate Prediction Center web site (El Niño/La Niña Current Conditions and Expert Discussions). Additional perspectives and analysis are Neutral conditions have returned to the tropical Pacific. We quantify, at high temporal resolution, the impacts of The 2020-2021 La Niña event has concluded, according to both oceanic and atmospheric indicators. This post discusses The Oceanic Niño Index (ONI) is used to identify El Niño (warm) and La Niña (cool) events in the tropical Pacific. The latest forecasts from the WMO Global Producing Centers of Long-Range Climate models disagree on how the year-to-year variability of the El Niño/Southern Oscillation will change in a warmer world. The The greatest source of seasonal climate variability is the El Niño—Southern Oscillation (ENSO), which drives changes in rainfall and surface temperatures worldwide (van Oldenborgh et al In summary, ENSO-neutral is favored for the remainder of summer (~60% chance in the July-September season), with La Niña possibly emerging during the August-October season and lasting through the El Nino Weather. National Meteorological and Hydrological Services will closely monitor changes in the state of El Niño/Southern Oscillation (ENSO) over the The El Niño–Southern Oscillation is a single climate phenomenon that periodically fluctuates between three phases: Neutral, La Niña or El Niño. La Niña is favored to continue for the next month or two, with a transition to ENSO-neutral most likely The WMO El Niño/La Niña Update is prepared approximately every three months through a collaborative effort between WMO and the International Research Originating in the equatorial Pacific, the El Niño–Southern Oscillation (ENSO) has highly consequential global impacts, motivating the need to understand its responses to anthropogenic The likelihood for El Niño development remains very low during winter and spring time; however, it increases up to 29% at the end of the La Niña conditions have developed. Effects of the El Niño–Southern Oscillation (ENSO) on the interannual variability in spring aerosols over East Asia are investigated using El Niño/La Niña InformationPersistent below-average sea surface temperatures across the central and eastern Pacific signal that La Niña conditions are favored For the upcoming winter season, which extends from December 2021 through February 2022, there is an 87% chance of La Nina. Atmospheric anomalies over the tropical Pacific Ocean are consistent with La Niña. 4 region for nine overlapping 3-month periods. Our blogger looks ahead to the rest of 2021. La Niña is expected to continue with an 87% chance in December 2021- February 2022. National Meteorological and Hydrological Services (NMHSs) will closely monitor changes in The 2020-2021 La Niña event has ended and neutral conditions (neither El Niño or La Niña) are likely to dominate the tropical Pacific in the next few months, Oceanic and atmospheric conditions are updated weekly on the Climate Prediction Center web site (El Niño/La Niña Current Conditions and Expert Discussions). This La Niña is what’s known as a ‘double-dip’, meaning it has formed for a For the second year in a row, the cooler sister to El Niño showed up at the winter party in the Eastern Pacific. Additional perspectives and analysis are El Niño/La Niña Updates The WMO El Niño/La Niña Update is prepared approximately every three months through a collaborative effort between WMO ENSO Forecast December 2021 Quick Look Published: December 20, 2021 A monthly summary of the status of El Niño, La Niña, and the Southern Most models indicate that the 2021/2022 La Niña is likely to be a weak-to-moderate event. The El Niño/Southern Oscillation (ENSO) is the most important climate index for seasonal and subseasonal forecasting. Note that the Guest blogger John Allen recaps tornado activity so far in 2021 and discusses the limits of using ENSO to predict seasonal tornado activity.
