本文在两次相关分析的基础上,讨论了海流区海温与副高特征量相关的特点及高相关区的时空演变特征。发现大部分高相关区的演变可分成移动型和准静止型两种。相关区移动或摆动的起点多集中在黑潮区、洪堡德海流区和热带东太平洋海区。同时对几个相关现象的可能物理原因做了初步分析,表明海温影响副高的途径是多种多样的;有下垫面的直接加热的影响;有下垫面加热影响其它环流系统,再通过此系统与副高的相互制约进而影响副高;还有通过经向垂直环流影响等等。
Based on the two correlation analyzes, the paper discusses the characteristics of the correlation between the sea temperature and the subtropical high in the current area and the temporal and spatial evolution characteristics of the high correlation area. It is found that the evolution of most high correlation zones can be divided into two types: moving and quasi-stationary. The starting point for the movement or swinging of the relevant areas is mostly concentrated in the Kuroshio, Honabutai currents and the tropical East Pacific. At the same time, the possible physical reasons of several related phenomena are analyzed preliminarily. The results show that there are many ways that the SST affects the subtropical high, the direct heating of the underlying surface, the heating of the underlying surface and other circulation systems, and then Through the mutual restraint between the system and the subtropical high then affect the subtropical high; there are vertical circulation through the vertical impact and so on.
