摘要:
为分析ENSO对登陆广东省热带气旋影响,选用1951~2016年登陆广东省热带气旋统计数据,分析与ENSO特征值之间的关系.研究结果表明:登陆广东省热带气旋年内变化和年际变化较大,年际变化总体呈现波动下降的趋势;登陆广东省的热带气旋主要集中于粤西沿海,特别是湛江东部沿海区域;厄尔尼诺年登陆广东省热带气旋数(2.74次)低于拉尼娜年热带气旋数(4.50次),但登陆的热带气旋强度相对较高;登陆广东省的热带气旋与Nino3.4海洋表面温度距平值( SSTA )、海洋尼诺指数( ONI )和南方涛动指数( SOI )等ENSO特征值呈现显著相关关系.

Abstract:
In order to analyses the effect of ENSO on the tropical cyclone landed in Guangdong the research was conducted on the relationships between tropical cyclone and eigenvalue based on statistical data of the tropical cyclones landed in Guangdong during 1951~2016. The results indicate that the tropical cyclones shows a general trend of decreasing annually accompanied by greater interannual and intermonth variations. In western coast Guangdong, tropical cyclones occurred much frequently, especially in the coast zone of Zhanjiang. There were less frequencies but relatively stronger tropical cyclone landed in Guangdong in EL Nino years (average 2.74 times per year) than in La Nina (average 4.50 times per year). The influence of the Nino3.4 SSTA , ONI and SOI on the tropical cyclone landing in Guangdong are characterized by their significant correlations.
