| 摘 要： | 在本文中,利用运动方程在β平面条件下,求得了无辐散运动的局地势。从它推出了涡度守恒原理。也就是说,当局地势为最小时,运动是满足涡度守恒的。在文中,还对涡度方程的Lagrange函数、能量等问题作了简单的分析。

| Abstract: | In this paper, the local potential of non-divergence flow on Beta plane is derived from the momentum equation. The conservative principle of vorticity is obtained when the local potential tends to minimum with the variational technique. Some other properties such as Lagrangian of vorticity equation, energy etc. are also discussed briefly here. |
