The global climate system is experiencing a significant change as the La Ni\u00f1a phenomenon, known for cooling the planet and affecting weather around the world, has ended after three months, according to the US agency NOAA. (National Oceanic and Atmospheric Administration) the weak La Ni\u00f1a that only appeared in January \u2013 much later than expected \u2013 is now a thing of the past. The Earth is currently in neutral phase of the El Ni\u00f1o\u2013Southern Oscillation (ENSO) cycle<\/strong>This condition, in which ENSO Alert System Status is not active<\/strong>, is the mildest of the three possible (El Ni\u00f1o, La Ni\u00f1a, neutral), but it also makes long-term weather forecasts more difficult because none of the extreme forces (cooling or warming of the Pacific Ocean) currently significantly affect global climate patterns.<\/p>\n

Current conditions reflect a persistent ENSO-neutral state. Sea surface temperatures (SSTs) are near average<\/strong> over most of the equatorial Pacific Ocean, with the latest weekly El Ni\u00f1o index values ranging from -0.1\u00b0C to +0.4\u00b0C. Subsurface ocean temperatures were near or above average over the 180\u00b0-100\u00b0W range, with above-average temperatures at greater depths in the central and western Pacific. Low-level winds were easterly over the east-central Pacific throughout the month, while high-speed winds were mostly near average across the equatorial Pacific. Convection was enhanced over Indonesia. Collectively, the coupled ocean-atmosphere system in the tropical Pacific reflects an ENSO-neutral state.<\/p>\n

La Ni\u00f1a is defined as cooling of surface water in the central equatorial Pacific Ocean<\/strong>Its typical impacts are far-reaching and include more hurricanes in the Atlantic (although not this year), drought in the southern and western United States, and more rainfall in Indonesia, northern Australia, and southern Africa. Studies show that the consequences of La Ni\u00f1a are more often economically demanding<\/strong> than during an El Ni\u00f1o or neutral phase. For example, last year, its phase caused droughts, food shortages and extreme heat in some regions.<\/p>\n

In Europe, the effects of La Ni\u00f1a are most pronounced in the winter months. There are two key areas in the Pacific Ocean \u2013 the Eastern (EP) and the Central (CP) \u2013 where the cold anomaly will occur. Cold in the EP area usually means fewer storms and more high pressure areas, leading to drier and colder weather in Western Europe. Conversely, cold in the CP area supports a stronger jet stream and more storms, leading to wetter, windier and milder winters. However, it is important to note that even though these are models, meteorologists warn that Other factors also affect European weather<\/strong> such as the North Atlantic Oscillation (NAO), stratospheric winds, or convection over the Indian Ocean.<\/p>\n

As for future predictions, ENSO-neutral state is very likely in the summer of 2025 in the Northern Hemisphere (with an 82 % chance in June-August)<\/strong>. This condition is projected to continue into the winter of 2025-26, although confidence in this scenario is lower. For the November-January period, there is a 48 % chance of a continuation of the neutral condition and a 41 % chance of a return of La Ni\u00f1a. IRI and North American Multi-Model Ensemble forecasts also suggest that ENSO-neutral is most likely until winter 2025-26<\/strong>, with a smaller chance that La Ni\u00f1a could form during this winter.<\/p>\n
