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 ...
The official designations by NOAA of "La Niña" and "El Niño" haven’t been around long, with widespread usage only dating back to the 1980s. Original article source: La Nina’s impacts were ...
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 ...
On Thursday, NOAA issued a La Niña watch, explaining that it could replace El Niño before the end of summer. This could have implications for the impending Atlantic hurricane season and beyond.
Next, Subtropical Storm Don formed over the central Atlantic on July 14. A long-lived storm, it later became fully tropical and strengthened into the season's first hurricane as it meandered around the ocean far from land. [12] [13] Following a lull in activity, tropical cyclogenesis picked up drastically in late August.
The switch to La Niña historically signals a more active hurricane season. However, what has some experts, like weather and climate specialist Dr. Marshall Shepherd, concerned are the ...
A markedly increased Walker circulation causes a La Niña by intensifying the upwelling of cold deep sea water; which cools the sea surface to below average temperatures. During non-El Niño conditions, the Walker circulation is seen at the surface as easterly trade winds that move water and air warmed by the sun toward the west.
It turned out hurricane season didn’t need La Niña in order to deliver devastating impacts anyway. The delay likely ties back to global ocean temperatures, which have been far above average for ...
