一、引言本研究第一部分建立了一个弱非线性、依赖深度的潮汐模式,这里将要介绍的则是该模式应用到乔治滩南、北两侧的情况。乔治滩位于大西洋西北的缅因湾口,是一个宽约150公里、长约300公里的海底滩,滩峰在水下一般为20—30米。绕此浅滩有一支顺时针方向余环流(见图1)。Loder(1980)使用一维非线性潮汐模式研究了该环流的特征及其形成机理。他首次指出:因地形等原因使得强潮流出现非线性效应是形成该环流的重要原因之一。Greenberg
I. INTRODUCTION The first part of this study establishes a weakly nonlinear and depth-dependent tidal model. Here we will introduce the model applied to the south and north sides of George Beach. Georgetown is located in the mouth of the mouth of the Gulf of Mexico at the mouth of the Gulf of Mexico in the northwest Atlantic Ocean. It is a submarine beach about 150 km wide and about 300 km long. The beach peak is usually 20-30 meters underwater. Around this shoal there is a clockwise circulation (see Figure 1). Loder (1980) studied the characteristics of the circulation and its formation mechanism using one-dimensional nonlinear tidal model. He pointed out for the first time: Due to the terrain and other reasons, the non-linear effect of the strong tide is one of the important reasons for the formation of the circulation. Greenberg
