  In this paper, we systematically study the existence, asymptotic behaviors,
uniqueness, and nonlinear orbital stability of traveling-wave solutions with
small propagation speeds for the generalized surface quasi-geostrophic (gSQG)
equation. Firstly we obtain the existence of a new family of global solutions
via the variational method. Secondly we show the uniqueness of maximizers under
our variational setting. Thirdly by using the variational framework, the
uniqueness of maximizers and a concentration-compactness principle we establish
some stability theorems. Moreover, after a suitable transformation, these
solutions constitute the desingularization of traveling point vortex pairs.
