The 2020–2023 La Niña event was a rare three-year, triple-dip La Niña. [1] The impact of the event led to numerous natural disasters that were either sparked or fueled by La Niña. La Niña refers to the reduction in the temperature of the ocean surface across the central and eastern equatorial Pacific, accompanied by notable changes in the ...
However, for the following three-month period running from March-May 2025, there's a 60% chance for La Niña to fade with the climate pattern returning to neutral status – neither La Niña or El ...
There is more than a 50% chance of La Niña developing in the next three months, the World Meteorological Organization (WMO) said on Wednesday, but if it does it will be relatively weak and short ...
La Niña is a cooling of Pacific Ocean surface temperatures west of equatorial South America, and that trend is developing gradually, the Climate Prediction Center said in an Oct. 10 statement.
According to CPC Deputy Director Mike Halpert, any such La Niña was expected to be "weak and potentially short-lived", but it could still affect the season. He also noted that La Niña years normally result in colder-than-average, wetter winters in the northern tier of the United States and the inverse conditions across the south.
There is a distinct rainy season when tropical cyclones occasionally visit between November and April. The dry season lasts from May to October. [78] During El Niño events, precipitation averages about 10 percent above normal, while La Niña events lead to precipitation amounts which average close to 10 percent below normal. [79]
La Niña happens when Pacific waters cool, moving the tropical thunderstorms so that the wind shear in the Atlantic wanes during hurricane season. La Niña watch: High chances the hurricane ...
During La Niña years, the formation of tropical cyclones, along with the subtropical ridge position, shifts westward across the western Pacific Ocean, which increases the landfall threat in China. [182] In March 2008, La Niña caused a drop in sea surface temperatures over Southeast Asia by 2 °C (3.6 °F).
