摘要

Abstract

Based on more than 30 years observed sectional temperature data since the 1960s

and compared with multi-year wind and Changjiang (Yangtze) River discharge data

spatial-temporal variations of the East China Sea Cold Eddy (ECSCE) in summer was analyzed in relationship to ocean circulation and local atmospheric circulation. Empirical Orthogonal Function (EOF) and Singular Value Decomposition (SVD) analyses were applied to this study. The results show that; 1) The ECSCE in summer possesses significant interannual variabilities

which are directly associated with oceanic and atmospheric circulation anomaly. Main fluctuations demonstrate their falling in basically with El Niño events (interannual) and interdecadal variability. 2) The ECSCE in summer is closely related to the variation of the Yellow Sea Warm Current (YSWC) and the Changjiang River discharge. The stronger the YSWC

the more intensive the ECSCE with its center shifting westward

and vice versa. However

a negative correlation between the Changjiang River discharge and the ECSCE strength is shown. The ECSCE was strengthened after the abrupt global climate change affected by the interdecadal variation of the YSWC. 3) SVD analysis suggested a high correlation between the variation of the ECSCE in summer and the anomalous cyclonic atmospheric circulation over the ECS. Intensification of the cyclonic wind strengthens the ECSCE

and vice versa. 4) The cyclonic atmospheric circulation has dominant influence on the interannual variation of the ECSCE

and the influence of the ocean circulation takes the second in. The ECSCE was usually stronger in El Niño years affected by strong cyclonic circulation in the atmosphere. The variation in strength of the ECSCE resulted from the joint effect of both oceanic and atmospheric circulation.
