摘    要:对7月500hPa西太平洋副高的高度场格点历史资料进行EOF分解,在相关普查的基础上,分别建立前5个特征向量所对应的时间系数的预报方程,然后用预报的主成分求得7月西太平洋副高500hPa高度场的预报值,对2003年7月西太平洋副高形势进行试报,并对2003年7月西太平洋副高异常的成因进行了探讨。

关 键 词:西太平洋副高  预报  EOF分解

Abstract:In order to forecast the circulation and shape of subtropical high over the west pacific in summer quantitatively, firstly, we have resolved the 500hPa height field over west pacific in July in "EOF" method; Secondly, on the basis of correlation survey, in the essay, we have set up five forecast equation respectively, which former eigenvector of subtropical high act in response of time coefficient; Thirdly, we have received the forecast charts of 500hPaheight field over west pacific in July that we have gained with time coefficient. Then, the forecast conclusion for July in 2003 was satisfied.
Keywords:subtropical high over the west pacific  eigenvector  principal composition  high pressure of south China sea
