The 2010–2012 La Niña event was one of the strongest on record. It caused Australia to experience its wettest September on record in 2010, and its fourth-wettest year on record in 2010. [ 2 ] [ 3 ] It also led to an unusual intensification of the Leeuwin Current , [ 4 ] the 2010 Pakistan floods , the 2010–2011 Queensland floods , and the ...
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. [213] 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. [214]
The El Niño event also contributed to the Earth's warming trend, with 2014 and 2015 being two of the warmest years on record. [ 48 ] [ 49 ] [ 50 ] Over 60 million people faced hunger and malnutrition in 2016 due to drought effects influenced by ENSO, with Africa worst hit, Indochina faced a severe drop in food production, and Ethiopia counted ...
The second, more devastating phase was caused by a very strong La Niña event, which lasted from June 2010 to June 2011. According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed. That same La Niña event also had devastating effects in the Eastern states of Australia.

1903–04 were La Niña years, which followed the Federation drought, though two major El Niño events in 1902 and 1905 produced the two driest years across the whole continent, whilst 1919 was similarly dry in the eastern states apart from the Gippsland. 1906–07 were moderate La Niña years with above-average rainfalls. 1909 to early 1911 ...
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 ...
In the absence of other short-term influences such as volcanic eruptions, strong El Niño years are typically 0.1 °C to 0.2 °C warmer than the years immediately preceding and following them, and strong La Niña years 0.1 °C to 0.2 °C cooler. The signal is most prominent in the year in which the El Niño/La Niña ends. [citation needed]
