Abstract
In winter, a thermohaline front is formed at the boundary between the Yellow Sea and East China Sea where warm and saline water of Kuroshio origin meets cold and fresher coastal water(Lie et al., 2000). The warm and saline Cheju Warm Current water in the northern East China Sea shelf advances westward in a tongue shape, whereas the YS cold water in the Chinese coastal area extends southeastward onto the Changjiang Banks. The warm water intrusion in the deep Yellow Sea trough has long been believed to meet the upwind flow theory (Park, 1986) that in an elongated basin, the wind-driven flow is upwind in the deep channel. Now we may pose the following question : Is the upwind flow theory still valid in the frontal zone? In this study, we will present some observational results which do not satisfy the upwind theory. Figure. Low-passed surface wind at 3m above sea surface, current at 23 m, and temperature at 28 m near Soheungsan-do in 2003. Wind direction is chosen in the same way as the current direction.1.
