The application of altimetry data to the Asian Marginal Seas

摘要

The altimetry data sets of satellite TOPEX/Poseidon and ERS-2 in the Asian marginal seas, the South China, the East China, the Yellow, the Japan/East and Okhotsk Seas, are produced applying the original tidal correction. In order to obtain a mean sea surface current field in the East China and the Japan/East Seas, the mean sea surface current is evaluated using ARGOS buoy trajectories data and altimetry data. From the mean sea surface current field, it is found that the northward current from the Kuroshio region to the Tsushima/Korea Strait exists throughout the year. The mean current field represents the detailed current feature in the Japan/East Sea such as the current path of Tsushima Warm Current.
