| Abstract: |
| In this paper, we study the problem of quasi geostrophic vortex equation with complete Coriolis force in mid and high latitude. By means of space-time scaling transformation, we obtain the conclusion of inhomogeneous mKdV-Burgers equation for describing the amplitude form of Rossbywave. The approximate solution shows that the weak topographic effect forces the amplitude of Rossbywave, which generalize the results in literature[12]. |
