标题： Interaction of two point vortices with an external wave: Application to plasma drift waves

摘要： 集中涡旋与自生成波的复杂相互作用是通过在外部波存在下的点涡模型进行研究的。 尽管该模型简单，但表现出丰富的动力学行为，包括偶极子的振荡、两个同环量涡旋的分裂和合并以及混沌。 该模型的分析和数值结果已被发现，在某些条件下可以预测更复杂系统的的行为，例如Charney-Hasegawa-Mima方程（漂移波或地转流）中的涡旋，其中波的存在强烈影响大相干结构的演化。 显示英文摘要

摘要： The complex interactions of concentrated vortices with self-generated waves is investigated using a model of point vortices in the presence of an external wave. In spite of its simplicity, this model shows a rich dynamical behavior including oscillations of a dipole, splitting and merging of two like-circulation vortices, and chaos. The analytical and numerical results of this model have been found to predict under certain conditions, the behavior of more complex systems, such as the vortices of the Charney-Hasegawa-Mima equation (drift waves or geostrophic flows), where the presence of waves strongly affects the evolution of large coherent structures.
