when did the most recent el niño occur
El Niño It is thought that there have been at least 30 El Niño events since 1900, with the 1982-83, 1997–98 and 2014–16 events among the strongest on record.[13][14] Since 2000, El Niño events have been observed in 2002–03, 2004–05, 2006–07, 2009–10 and 2014–16.[13]
El Niño Historically, El Niño events are thought to have been occurring for thousands of years.[11] For example, it is thought that El Niño affected the Moche in modern-day Peru, who sacrificed humans in order to try to prevent the rains. Scientists have also found the chemical signatures of warmer sea surface temperatures and increased rainfall caused by El Niño in coral specimens that are around 13,000 years old.[12] In around 1525 when Francisco Pizarro made landfall on Peru, he noted rainfall occurring in the deserts which subsequently became the first written record of the impacts of El Niño.[12] Modern day research and reanalysis techniques have managed to find at least 26 El Niño events since 1900, with the 1982-83, 1997–98 and 2014–16 events among the strongest on record.[13][14][15]
Paris Peace Accords
El Niño Originally the term El Niño applied to an annual weak warm ocean current that ran southwards along the coast of Peru and Ecuador at about Christmas time.[6] However, over time the term has evolved and now refers to the warm and negative phase of the El Niño Southern Oscillation and is the warming of the ocean surface or above-average sea surface temperatures in either the central and eastern tropical Pacific Ocean.[7][8] This warming causes a shift in the atmospheric circulation with rainfall becoming reduced over Indonesia and Australia, while rainfall and tropical cyclone formation increases over the tropical Pacific Ocean.[9] The low-level surface trade winds, which normally blow from east to west along the equator, either weaken or start blowing from the other direction.[8]
