This study was first planned based on the paper "Dynamical study on the bay-typed shelf circulation and heat and water mass transport across the shelf break" by T.Sugimoto and J.A.Whitehead (1983). This theoretical and experimental study was extended to the infinite long shelf without side wall boundary (Whitehead, 1993) and its nonlinear theory (Whitehead and Kimura, to be published). Kimura also investigated generation and evolution of the frontal eddies in the rotating hydraulic model (Kimura et al., 1993).Comparative study on the shelf break circulations and coastal boundary circulations of the western boundary currents between the Kuroshio and the Gulf Stream was also conducted, mainly by T.Sugimoto and H.Nakata. In this study fluctuation of the Kuroshio front and the accompanying frontal eddies and streamers are precisely investigated through intensive field observations (Kasai et al., 1993).In relation to material exchange in and around the shelf break, Y.Hozaki in ORI and S.Honjo in WHOI worked to make clear the dispersion of the dissolved and suspended matters, respectively, from the Yangtze River on and across the East China Sea shelf (Nozaki, 1991).

这项研究最初是根据T.Sugimoto和J.A.Whitehead(1983)的论文《关于湾型陆架环流和跨陆架断裂的热量和水质量输送的动力学研究》进行的。这一理论和实验研究被扩展到无侧壁边界的无限长货架(Whitehead，1993)及其非线性理论(Whitehead和Kimura，即将出版)。Kimura还研究了旋转水力模型中锋面涡的产生和演化(Kimura et al.，1993)。T.Sugimoto和H.Nakata也对黑潮和墨西哥湾流之间西部边界流的陆架破裂环流和海岸边界环流进行了比较研究。在这项研究中，通过密集的现场观测，精确地研究了黑潮锋面和伴随的锋面涡旋和流光的波动(Kasai等人，1993年)。关于陆架断裂及其周围的物质交换，ORI的Y.Hozaki和WHOI的S.Honjo分别研究了来自长江的溶解物质和悬浮物在东中国陆架上和横跨东海陆架的扩散(Nozaki，1991年)。
