从Petviashvili方程出发，讨论了具有标量非线性效应的Rossby偶极子的动力学.结果表明，Rossby偶极子的最终动力学特性取决于标量非线性、矢量非线性和背景流的相互作用等多种因素。标量非线性对Rossby阻塞偶极子的影响更为明显。由于两个非线性的平衡或其旋转结构，在Rossby偶极子演化中也观察到了跷跷板现象。
Based on the Petviashvili equation, dynamics of Rossby dipole with effect of scalar nonlinearity is discussed. It is shown that the final dynamics of Rossby dipole depends on many factors such as interaction of scalar nonlinearity, vector nonlinearity and background flows. The Rossby blocking dipole is affected by the scalar nonlinearity more evidently. The seesaw phenomenon is also observed in the Rossby dipole evolution due to the two nonlinearities balance or its rotation structure.
