Interannual variability of the southern Yellow Sea Cold Water Mass
Interannual variability of the southern Yellow Sea Cold Water Mass
摘要
Abstract
Temperature data collected in the sections of 34°N, 35°N and 36°N in August from 1975 through2003 were analyzed using Empirical Orthogonal Function (EOF) to investigate interannual variability of the southern Yellow Sea Cold Water Mass (YSCWM). The first mode (EOF1) reveals variations of basin-wide thermocline depth, which is mainly caused by surface heating. The second mode (EOF2) presents fluctuations of vertical circulation, resulting mainly from interannual variability of cold front intensity. In addition, it is found that the upward extent of upwelling in the cold front is basically determined by wind stress curl and the zonal position of the warm water center in the southern Yellow Sea is correlated with spatial difference of net heat flux.关键词
