Climate phenomenon La Niña, who usually cools the planet and affects the weather around the world, according to the US agency (National Ocean and Atmosphere National Authority) After three months he ended up. The weak La Niña, which appeared only in January – much later than expected – is a thing of the past, he says.
Currently, the Earth is located in the neutral phase of the El Niño -Southern oscillation (ENSO) cycle. This condition is of three possible (El Niño, La Niña, Neutral) the most dying, but at the same time make it difficult for long -term weather forecasts, Because none of the extreme forces (cooling or warming the Pacific Ocean) currently affects global climate patterns.
How does La Niña affect the world weather?
La Niña represents the cooling of the surface water in the central part of the equatorial Pacific Ocean. Typically, it brings more hurricanes in the Atlantic (but not this year), drought in the south and west of the US and more precipitation in Indonesia, Northern Australia and South Africa.
According to the studies, they are The consequences of La Niñy more often more economically demanding than during El Niña or neutral phase. Last year, her phase caused dry, lack of food and extreme heat in some regions.
In Europe, the effects of La Niñy are most manifested in the winter months. Two areas in the Pacific Ocean – East (EP) and Central (CP) – where the cold anomaly occur.
The cold in the EP region means fewer storms, more high -pressure outcrops, leading to drier and colder weather in Western Europe. Cold in the CP area, in turn, supports the stronger Jet Stream and more storms, which brings wetter, windy and milder winters. Although it is models, meteorologists point out that European weather is also influenced by other factors such as North Atlantic oscillation (NAO), stratospheric winds or convection over the Indian Ocean.
What to expect in 2025?
NOAA assumes that the neutral phase of the ENSO will persist the majority, if not the whole year 2025. This means that no strong climate signal will dominate. Still Meteorologists from Met Office expect 2025 to be one of the three hottest in history. March 2025 was already the hottest March in Europe, increasing the risk of heat and forest fires during the summer.
