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 ...
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 is known to enhance hurricane activity in the Atlantic basin, according to NOAA. Much of the impact is due to La Niña’s effects on wind shear and atmospheric conditions over the Atlantic.
The timing of La Niña's arrival may coincide with the peak of the upcoming Atlantic hurricane season. "A return to La Niña conditions quickly over the summer could result in an active tropical ...
A pokey La Niña doesn’t mean the rest of hurricane season, which runs through Nov. 30, will be sluggish. Thursday’s ENSO forecast came out the same day as NOAA’s updated hurricane ...
The map shows difference from average winter (November–March) precipitation during La Niña years (1954, 1955, 1964, 1970, 1973, 1975, 1988, 1999, 2007) compared to the long-term average (1971 ...
In early 2024, hurricane forecasters predicted a highly-active season, citing the La Niña effect and warm sea surface temperatures. [8] After the earliest-forming Category 5 hurricane on record, Hurricane Beryl, the US National Oceanic and Atmospheric Administration (NOAA) maintained this prediction through August. [9]
La Niña is a complex weather pattern that occurs every few years, [19] often persisting for longer than five months. El Niño and La Niña can be indicators of weather changes across the globe. Atlantic and Pacific hurricanes can have different characteristics due to lower or higher wind shear and cooler or warmer sea surface temperatures.
