New climate projections increase the probability of the formation of a super El Niño in 2026. The phenomenon could lead the planet to record new temperature records by 2027. Modelos of Centro Europeu of Previsão Meteorológica indicate that the event could reach exceptional intensity.
El Niño occurs when the waters of Oceano Pacífico heat up. The super version occurs when this warming exceeds 2 degrees Celsius. The possible new episode could surpass the 2015 record, when the temperature of Pacífico reached 2.8 degrees Celsius above average.
Climate model projections
Previsão Meteorológica’s Centro Europeu updated its estimates. Data shows high chance of strong or super El Niño conditions from mid-year onwards. Vários members of the model suite indicate anomalies above 2.5 degrees Celsius in specific periods.
Experts are monitoring the development of anomalous winds in the Pacífico west. Esses Winds contribute to warming surface waters. Professor Paul Roundy, from Universidade Estadual from Nova York to Albany, assesses that there is real potential for the most intense event in more than a century.
Analysis indicates that the phenomenon may develop between the end of 2026 and the beginning of 2027. Ainda therefore, the models maintain uncertainty about the final intensity. Variações natural resources and the context of global warming influence the result.
Characteristics of the phenomenon El Niño
El Niño changes atmospheric circulation patterns on a global scale. Ele modifies rainfall and temperature regimes in several regions. Eventos intense heat releases heat stored in the ocean into the atmosphere.
Scientists explain that the additional warming of surface water exceeds 0.5 degrees Celsius in the basic definition. In case of super El Niño, the deviation exceeds 2 degrees Celsius. Esse level affects monsoons, cyclones and heat waves.
The last major benchmark event occurred in 2015-2016. At the time, anomalies reached historic peaks in some regions of Pacífico. The new scenario is compared to rare episodes from recent decades.
- The warming of the waters of the central and eastern Pacífico characterizes the phenomenon
- Anomalies above 2 degrees Celsius define the super category
- Changes in trade winds contribute to development
- Effects persist for several months after the peak
Expected impacts on different continents
Regions of América Central, África Central, Austrália, Indonésia and Filipinas may face severe droughts. Países like Peru and Equador tend to record heavy rains and the risk of flooding. Ondas heat should become more frequent in parts of América of África Central0, south of África Central1, África Central2, África Central3, África Central4 África Central5.
Cyclone and typhoon activity in Pacífico may increase. No Atlântico, the forecast indicates a reduction in the number of hurricanes. Esses patterns derive from the redistribution of heat and moisture in the atmosphere.
In Brasil, the phenomenon is usually associated with drought in Nordeste. Sul records an increase in rainfall, as observed in previous episodes. Climatologist Karina Lima highlights that El Niño increases the chances of precipitation above average in Sul. Ela notes, however, that each event has particularities and multifactorial causes can influence results.
Effects on global temperature and agriculture
Strong events of El Niño contribute to an increase in the planet’s average temperature. The heat released from the ocean adds to the background warming caused by greenhouse gases. Projeções indicate that 2027 appears as a year with high potential for new records.
Meteorologist Eric Webb, from Departamento from Defesa from Estados Unidos, explains that the increasing concentration of greenhouse gases makes it difficult to dissipate heat between successive events. Essa Dynamics can amplify effects.
Farmers in many tropical regions face risks. Na Índia Reduced monsoon may affect production. In other areas, the combination of extreme heat and drought is putting pressure on crops and water supplies. Secas Prolonged conditions also increase the chance of forest fires.
Uncertainties and expert recommendations
Scientists reinforce that no event from El Niño is repeated in an identical way. Fatores locations and the current state of global climate introduce variability. Current projections indicate a trend, but do not guarantee exact intensity.
Continuous monitoring of ocean temperatures and equatorial winds remains essential. Órgãos International update models regularly with new data.
Long-term global warming changes the behavior of these phenomena. Especialistas follows how the interaction between El Niño and climate change can modify future extremes.
