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 ...
Wind magnitude is greater during El Niño years than during La Niña years, due to the more frequent cold frontal incursions during El Niño winters. [212] Tehuantepec winds reach 20 knots (40 km/h) to 45 knots (80 km/h), and on rare occasions 100 knots (190 km/h). The wind's direction is from the north to north-northeast. [213]
A typical La Niña pattern produces a wetter, cooler winter over the northern U.S., while drier, milder weather takes hold of the South. While there have been important caveats that go against the ...
The World Meteorological Organization said a 'triple dip' third year of La Nina climate patterns is the first time it has persisted this long in the 21st century.
The atmosphere started to look La Niña-like in the fall, but ocean temperatures didn’t really look like La Niña until the end of the year, Becker explained.
1949–51 were La Niña years, which had significant rain events in central New South Wales and most of Queensland: Dubbo's 1950 rainfall of 1,329 mm (52.3 in) can be estimated to have a return period of between 350 and 400 years, whilst Lake Eyre filled for the first time in thirty years. 1954–57 were also intense La Niña years. In contrast ...
La Niña was last in place from 2020 to 2023 — a period of time that included California's driest three years on record. The arid stretch shrank reservoirs to record lows, triggered Southern ...
Across Alaska, El Niño events do not have a correlation towards dry or wet conditions; however, La Niña events lead to drier than normal conditions.During El Niño events, increased precipitation is expected in Southern California, Arizona, and New Mexico due to a more southerly, zonal, storm track over the Southwest, leading to increased winter snowpack, but a more subdued summer monsoon ...
