Abstract
The second part of this work investigates the seasonal variabilities of the Japan/East Sea (JES) circulation
using the U.S. Navy Generalized Digital Environmental Model (GDEM) climatological temperature and salinity
dataset (public domain) on a 0.58 3 0.58 grid. A variational P-vector method was developed to invert the velocity
field. The GDEM for the JES was built up on historical (1930–97) 136 509 temperature and 52 572 salinity
profiles. The climatological mean and seasonal variability of the current systems are well inverted, especially
the Tsushima Warm Current and its bifurcation, the East Korean Warm Current (EKWC), the Japan nearshore
branch, the confluence of the EKWC, and the North Korean Cold Current near the Korean coast and flows
northeastward along the subpolar front, and a mesoscale anticyclonic eddy in the Ulleng/Tsushima Basin. Furthermore,
this method has the capability to invert flow reasonably well across the shallow straits such as the
Tsushima/Korea, Tsugaru, and Soya Straits. The GDEM temperature and salinity and the inverted velocity fields
provide balanced initial fields for JES numerical modeling and simulation.
