| 摘 要： | 本文是文献3]研究工作的继续。利用文献3]中所用的海-气边界层模式,重点考虑海深和底坡的影响,将该文的研究成果直接推广到有限深海的情形,和无限深海情形下所获得的相应结果进行比较,简洁地阐明两者的异同,并就海底摩擦以及浅海风暴潮的估值和导致风暴潮的发生和发展的大气强迫力作一简短讨论。

| Abstract: | This article is a continuation and a direct generalization of the authors research report 3] published just recently. By means of the same air-sea planetary boundary layer model as that used in 3],the physical diagnostic analyses of the wind and the current profiles, the surface wind stress,the bottom friction, the dissipation of energy and the Ekman pumping in the atmosphere as well as in the ocean under the actions of atmospheric large scale baroclinic disturbances are made systematically for an ocean of finite depth.The effects of the sea depth and the bottom topography on winds and ocean currents are emphasized in this study.The present author makes a succinct comparison between the results obtained in oceans of both infinite and finite depth. This article discusses briefly the atmospheric forcing functions which control the formation and the development of storm surge in shallow water.The magnitude of the storm surge and its characteristic time are numerically estimated.Moreover, some empirical hypotheses concerning wind stress along sea surface and bottom friction may be justified by the theory presented in this paper under some simple circumstances. The results may also be extended rationally to fit more complicated cases where the Coriolis effect due to earth rotation is noticeable. Besides revealing some mechanism of air-sea interaction, many conclusions reached by the theory show an agreement with the observations. |
