标题： Dynamics of vortices and drift waves: a point vortex model

摘要： 局部涡旋与波的复杂相互作用是通过在横向或纵向波存在的情况下点涡模型进行研究的。 这个简单的模型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方程中的涡旋，其中波的存在强烈影响大尺度相干结构的演化。 显示英文摘要

摘要： The complex interactions of localized vortices with waves is investigated using a model of point vortices in the presence of a transverse or longitudinal wave. This simple 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, where the presence of waves strongly affects the evolution of large coherent structures.
