一种新的厄尔尼诺指数
A new index for El Ni(n)o
摘要
Abstract
Using the monthly mean NOAA extended reconstructed sea surface temperature (ERSST) analyses data from 1950 to 2016,the commonly used E1 Ni(n)o index is calculated,and the monitoring abilities of several indices are examined.The results indicate that any single index cannot comprehensive monitor different types of E1 Ni(n)o events.The commonly used E1 Ni(n)o index has limitations on monitoring E1 Ni(n)o events.Therefore,this paper proposes a new E1 Ni(n)o index which not only can comprehensive monitor what has happened in the history at the different types of E1 Ni(n)o events,but also can reasonably define the strength of E1 Ni(n)o events.The new index can resolve the dispute in defining the intensity of El Ni(n)o events,and provide a new approach to monitoring of E1 Ni(n)o events.The study also analyses the impact of climate reference change on E1 Ni(n)o index for defining E1 Ni(n)o events,the results show that there will be fewer weak E1 Ni(n)o events with the increase of climate reference.关键词
