摘要：
The seasonal response of sea surface height anomaly (SSHA) to wind stress curl and Kuroshio intrusion over the Northern South China Sea (SCS) is studied using satellite observed SSHA from AVISO, cross calibrated multi-platform wind (CCMP), and numerical experiments. All the data are monthly averaged. The EOF analysis illustrates that on seasonal time scale wind stress curl shows a westward-propagating pattern that is highly correlated with the observed SSHA from AVISO. This is consistent with previous studies. By conducting experiments with beta-plane and f-plane models, we find that the f-plane model alone can explain a large % of the total variance of SSHA. Kuroshio intrusion is examined too. Its variation at seasonal cycle is strong in winter, but weak in summer, as many previous works have suggested. The intrusion shows a cyclonic type of circulation appears and tend to intrude SCS water west of Luzon Island into the NSCS, consistent also with beta-plume, and then propagating west-southwestward along the shelf break.
