摘要
In this paper,the local potential of nondivergent flow on beta plane is derived from the motion equa- tion.The conservation principle for vorticity is obtained when the local potential tends to be minimum with the variational technique.Some other properties st,ch as Lagrangian of vorticity equation,energy etc.are also discussed briefly in the paper.
