Based on early signs, expectations indicate that the probability of its occurrence is 50 percent, which is a striking number, given that it is twice the usual rate. Meanwhile, the US National Oceanic and Atmospheric Administration (NOAA) estimates the chance of summer formation at 69%, while the Japan Meteorological Agency expects it to reach 60% through November.
According to information provided by ABC News, the La Niña phenomenon could have a significant impact on a global scale, especially in the field of agriculture. More rain is expected in eastern Australia and southeast Asia, while the weather is expected to be drier in the Americas.
La Niña occurs with cold water surfaces, unlike El Niño, which causes temperatures to rise and has led to severe droughts around the world.
Australian meteorologists are particularly concerned that the presence of a large mass of cold water beneath the surface of the tropical Pacific Ocean portends more cold water upwelling, which could quickly facilitate the development of a La Nina phenomenon by mid-summer.
If this phenomenon does occur, it could indicate wetter weather in the eastern and northern parts of Australia in the coming winter and spring. There have been previous examples of it causing heavy rain and flooding in eastern Australia in 2021 and 2022. The La Nina phenomenon could also have a positive impact on India's monsoon season, which could be vital for the country's rice production.
They will be able to feel its effects globally; This is expected to affect wheat and corn production in the United States, as well as soybean and corn production in Latin America, including Brazil.
