| Abstract: | By using the conservation laws and the method of variational principle, an improved Arnol'd's second nonlinear stability theorem for the two-dimensional multilayer quasi-geostrophic model in periodic channel is obtained. This work is supported by the National Natural Science Foundation of China (No. 49455007). |
