涡和漂移波的动力学：一个点涡模式
Dynamics of vortices and drift waves: a point vortex model
摘要：
本文用点涡模型研究了存在横波或纵波时局部涡与波的复杂相互作用。这个简单的模型展示了丰富的动力学行为，包括偶极的振荡、两个类似环流涡旋的分裂和合并以及混乱。该模型的分析和数值结果已被发现在某些条件下预测，更复杂的复杂系统的行为，如查尼-长谷川-Mima方程的涡，其中波的存在强烈影响大的相干结构的演变。
英文摘要：
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.
