首先给出西太平洋副高脊线、面积和西伸指数的定义 ,在此基础上讨论赤道东太平洋海温异常与西太平洋副高的年际变化关系 ,并进一步分析了春季赤道东太平洋海温异常对西太平洋副高季节变化的影响。结果表明 ,春季赤道东太平洋海温异常与夏季副高位置和强度的年际变化及季节变化都有密切关系。从春季到夏季 ,春季海温偏暖年副高偏南、偏强、偏西 ;偏冷年副高偏北、偏弱、偏东 ,冷年 6月副高北跳较暖年显著 ,进入秋季后南撤更为迅速
First, the definition of the western Pacific subtropical high ridge, area and west extensibility index is given. On the basis of this, the relationship between the SST anomalies in the eastern equatorial Pacific and the interannual variation of the western Pacific subtropical high is discussed, and the relationship between the SST The Impact of Abnormality on the Seasonal Changes of the Western Pacific Subtropical High. The results show that the spring equatorial Pacific SST anomalies are closely related to the annual and seasonal variations of the summer subtropical high. From spring to summer, the spring sea surface temperature warmer in the next year is higher in the south, stronger in the west, while in the colder year, the subtropical high is northerly, weaker in the east and cold in June, South withdrawal after the fall more rapidly
