Abstract:

In this paper, we study the existence of counter-rotating vortex pairs with different scales and different distributions for the generalized surface quasi-geostrophic (gSQG) equation by using vorticity method. We construct a family of traveling asymmetric vortex pairs by using the variational method, and analyze the asymptotic behaviors of the family of vortex pairs.

Key words: The generalized surface quasi-geostrophic equation, Traveling-wave solutions, Vortex method
