Sea surface temperatures in the central Pacific have reached unprecedented levels since satellite records began, triggering an El Niño of such magnitude that scientists have not found an adequate scientific name for it.
What's happening: Nameless El Niño, temperature and humidity records
According to weather models, the thermal anomaly extends over more than half of the Pacific Ocean, with areas where heat is significantly above seasonal averages. This excessive heat translates into increased evaporation, which feeds the atmosphere with exceptional humidity. Early observations already show record precipitation along the west coast of South America, while northeast Asia records unusual rainfall deficits.
The phenomenon modifies the usual position of the intertropical convergence zone, pushing it southeast. This migration causes global climate perturbations: more intense storms in the southwest Pacific, prolonged droughts in Indonesia, and strengthening of southeasterly winds along the west coast of North America. ECMWF and Copernicus models confirm that the impact will persist for several months, exceeding classic El Niño cycle persistence.
In Europe, effects are already seen with a trend towards milder winters and increased precipitation in the Mediterranean basin. Forecasts indicate that France could experience a notable increase in autumn rainfall, especially in northeastern regions where depression systems intensify under the phenomenon's influence.
