Abstract
From 0.1° OFES (OGCM for the Earth Simulator) results provided by the JAMSTEC(Masumoto et al., 2004), we investigated the East China Sea circulation while focusingon the origin of the Tsushima Warm Current. The volume transport of the simulatedTsushima Warm Current is 1.7 Sv and is weaker than the observation. The KuroshioCurrent, however, is reproduced well, as well as the Taiwan Warm Current of about1.5 Sv. Considering that this global model is not optimized for the East China Sea, andthese flows are not determined by the lateral boundary conditions but by the internaldynamics, the model results are good enough for the purpose of this study. The modelresults show that the main part of the Tsushima Warm Current is a continuation of theTaiwan Warm Current. The complex interaction between the Taiwan Warm Currentand its extension with the Kuroshio to the east of Taiwan and to the west of Kyushuseems to be the main cause of confusions in previous studies based on sparse observationand low resolution modeling. The net intrusions of the Kuroshio into the EastChina Sea in those areas occur only seasonally.
