“…These features are different with the previous numerical results in that anti-clockwise circulation is confined mainly north of 42°N in winter, elongated east to west (Vasilev and Makashin, 1992) or even clockwise circulation is dominant in the northern half of the Japan Sea (Sekine, 1986(Sekine, , 1991. The reason is that the northern circulation simulated in the present model is largely dependent upon the characteristics of the adopted climatological wind stress field.…”

“…In the rest of the season it becomes almost zero or turns to small negative value from the positive (Na et al, 1992). However, the wind stress curl calculated from the global data set such as Hellerman and Rosenstein's (1983) or Kutsuwada and Sakurai's (1982) which Sekine (1986Sekine ( , 1991 used does not show such a salient characteristic of wind in this marginal sea.

The surface circulation in the Japan Sea is investigated using a 1.5 layer reduced gravity model. Historical observations suggest strongly that an anti-clockwise circulation is dominant in the subpolar region north of the Polar Front as a general feature. This anti-clockwise circulation as well as the branching of the Tsushima Warm Current was simulated well by incorporating the Na et al. (1992)'s wind stress. The positive curl of the wind stress in the northern and the northwestern Japan Sea was found to play an important role in the formation of the subpolar gyre and the separation of the western boundary current (the East Korean Warm Current) in the Japan Sea.

“…Although the Tsushima Current is salty relative to the water entering the JES from the north, it is fresh compared to the Pacific water from which it originated because of significant dilution by freshwater from both the Yangtze River and the Yellow River (Tomczak and Godfrey 1994). For other general aspects of the JES circulation the reader is referred to Minato and Kimura (1980), Toba et al (1982), Sekine (1986Sekine ( , 1988, Sugimoto (1990), Preller and Hogan (1998), and Hogan and Hurlburt (2000).…”

China's Development Could Lead to Bottom Water Formation in the Japan/East Sea

Using hydrographic data and box models, it is shown that the presently discussed diversion of rivers such as the Yellow or the Yangtze for agricultural use is likely to cause the renewal of Bottom Water formation in the Japan/East Sea. Such formation was common (near the Siberian coast) in the 1930s, 1940s, and 1950s, but subsided since that time due to a warming trend (accompanied by a decreased salinity due to the melting of ice). Since a diversion of freshwater is analogous to evaporation, a (diversion induced) increase of salinity is expected and the increase is large enough to allow Bottom Water formation even at the present-day cooling rates. Even a modest diversion of "merely" 3000 m 3 s-1 (which is 10% of the total freshwater flux) will probably cause Bottom Water formation at a rate of roughly 750 000 m 3 s _1. This is the first study that predicts anthropogenic reversal of an existing vertical structure in a semienclosed sea.

Why much of the Atlantic circulation enters the Caribbean Sea and very little of the Pacific circulation enters the Sea of Japan

A peculiar aspect of western marginal seas is that some of them accommodate large transports whereas others, apparently similar seas, accommodate relatively small transports. For instance, about 30-40 Sv of Atlantic upper water passes through the Caribbean and yet only 2 Sv or so passes through the Sea of Japan. The passages connecting the Caribbean to the Atlantic are somewhat larger than their Sea of Japan counterparts, but the dimensions of the gaps are too similar to each other to account for the large difference in the transports.Four different baroclinic models are used to investigate the problem. First, we used a winddriven, layer-and-a-half isopycnal model with an idealized basin and an adjacent marginal sea separated from the main basin by a thin and long island. In this scenario, thermocline water enters the marginal sea via a gap to the south of the island and exits the sea via a gap to the north of the island. The mean latitudinal position of the marginal sea is gradually increased and the numerical transport across the sea is measured. We then compared the transport determined this way to that computed using three analytical baroclinic models: Godfrey's island rule (Godfrey, J. S. (1989). A Sverdrup model of the depth-integrated flow for the world ocean allowing for island circulations. Geophysical and Astrophysical Fluid Dynamics, 45,, the 'b-controlled' transport formula (Nof, D. (1993). The penetration of Kuroshio water into the Sea of Japan. Journal of Physical Oceanography, 23,[797][798][799][800][801][802][803][804][805][806][807], and the general gap transport formula (Nof, D., (1995). Choked flows and wind-driven interbasin exchange. Research, 53,. The results were also compared to Minato and Kimura's (Minato, S., & Kimura, R. (1980). Volume transport of the western boundary current penetrating into a marginal sea. Journal of the Oceanographic Society of Japan, 36,[185][186][187][188][189][190][191][192][193][194][195] barotropic calculations. Journal of MarineAll four baroclinic models show that, when the marginal sea is situated in low and mid latitude, the penetration of thermocline water into the marginal sea decreases rapidly with increased latitude. By contrast, in equatorial marginal seas, the penetration of thermocline water increases with increasing latitude. Minato and Kimura's (1980) barotropic model shows a similar behavior except that the maximum transport occurs at a much higher latitude. Excellent agreement between the numerics and Godfrey's island rule formula is found in equatorial seas.As the latitude of the marginal sea increases to low and mid latitudes, the deviations from the numerics increase dramatically though the agreement is still very reasonable. Both the b-controlled formula and the gap formula are relatively accurate in mid latitudes when the sea is close to the separation latitude. The importance of frictional forces within the western boundary current results in the b-controlled formula failing for marginal seas situated far away from the separation la...
