| 摘 要： | 根据1967-2016年揭阳市4个国家气象站(揭阳市区、揭西、普宁、惠来)的观测资料以及Nino3+4区的海温指数(ONI),分析了揭阳市降水量、暴雨日数与厄尔尼诺/拉尼娜事件的关系。结果表明,50a来揭阳市的年降水量呈现出年际和年代际波动起伏的特点。在厄尔尼诺/拉尼娜事件发生时,揭阳春季降水主要表现为偏多/偏少,秋季降水主要表现为偏少/偏多,秋季暴雨日数主要表现为偏少或偏多;冬季暴雨只出现在厄尔尼诺事件或拉尼娜事件发生的年份。

| Abstract: | Based on the meteorological data of four national meteorological stations(Jieyang, Jiexi, Puning and Huilai) in Jieyang City from 1967 to 2016 and the sea surface temperature index(ONI) in Nino 3+4 area,the relationship between precipitation, rainstorm days and El Nino/La Nina events in Jieyang City was analyzed.The results showed that the annual precipitation of Jieyang City in the past 50 years had the characteristics of interannual and interdecadal fluctuation. In the event of El Nino/La Nina, the precipitation of Jieyang in spring was more/less, while that in autumn was less/more. In the event of El Nino/La Nina, the number of rainstorm days in autumn was mainly less/more;winter rainstorm only occurred in the year of El Nino event or La Nina event. |
