摘　　要：文中导得了N层模式的KdV方程,作为例子计算了三层模式的孤立Rossby波流型。基本气流的垂直切变、水平切变和Froude数对孤波流型都有重要影响;不同模态的孤波具有不同流型,不同高度位面上的孤波流型一般是不同的。The KdV equation is derived from a N-level model. The streamline patterns of solitary Rossby waves are calculated with a three-level model. The results show that the influence of the vertical and horizontal shears of the basic flow and Froude number on the solitary Rossby waves is quite important. The streamline patterns of the solitary waves with different modes are different.
