Most of the study on correlation between the subtropical high and SST focus on the location or intensity of the former versus the latter. It is worthwhile to work on links other than what is usually addressed to identify guidelines in the prediction of the subtropical high. Based on the analysis of subtropical high in west Pacific summer and its correlation with SST in equatorial and north Pacific from previous December to subsequent November, correlation between the area index, west-extending point, location of the subtropical high ridge and SST is discussed. It is conducted by looking into the confidence level of gridpoints and their percentage in the total and examining how they vary with time. From the point of intensity and movement/expansion, feedbacks from the subtropical high to SST are also studied. The SST affects the subtropical high just as the subtropical high affects the SST. A linkage model is thus set up to assist the making of summer rainfall prediction in China’s raining seasons.
