【 摘 要 】

Based on AVISO satellite altimetry data, the seasonal and spatial patterns of the sea surface height anomaly (SSHA) during 1993-2015 in the East China Sea (ECS) were determined. The SSHA variations related to thermo-steric effects were evaluated. Significant seasonal variations of the SSHA in the ECS were observed. The SSHA was lower in winter and spring and higher in summer and autumn. The peak values of the SSHA lagged behind those of sea temperature by one month. The regional distribution of the SSHA was obvious in different seasons because of sea depth and dynamic ocean processes. The annual mean growth rate of the SSH in the ECS during 1992-2015 was 2.82 mm.y-1.
