A correlation characteristics analysis of monthly sea surface temperature of 13 sea areas (mainly strong ocean-current areas) and 15 subtropical highs is made, and the characteristics of the time-space variation of high-correlation areas are discussed. On the basis of a preliminary analysis of the possible physical mechanism for several related phenomena, it is concluded that SST affects subtropical high through a variety of ways.
