2014-2016年超强厄尔尼诺事件的气候影响
Influences of the 2014-2016 Super El Niñno Event on Climate
摘要
Abstract
A super El Niñno event occurred over the equatorial central-eastern Pacific during 2014-2016.It peaked in November 2015 with its strength larger than two other super El Niñno events (1982/1983 and 1997/1998 events),ranking as the strongest El Niñno event since 1951.By April 2016,it has lasted for 20 months,thus becoming the longest El Niñno event since 1951.During the developing process of this El Niñno,the atmospheric circulation from the tropical Pacific to East Asia has shown significant responses. The convection over the equatorial central-eastern Pacific was more active than normal,and anomalously ascending motion.However,over the equatorial western Pacific,the convection was inhibited and anoma-lous subsidence prevailed.The anomalous low-level Philippine Sea anticyclone persistently controlled northwestern Pacific and became gradually stronger with the development of El Niñno.As a result,the western Pacific subtropical high (WPSH)has become stronger than normal,and its west boundary extend-ed more westward.The WPSH in winter 2015 has been the strongest since 1980.Meanwhile,precipitation was above normal in the southern part of the Yangtze River Valley in China during autumn and winter of 2015,with the mean precipitation over South China (Guangdong,Guangxi and Hainan)in winter 2015 ranking as the first since 1951.Recently,this super El Niñno event has been decaying.However,its further influences on the cli-mate anomaly in China may still persist during the following spring and summer of 2016.关键词
