Abstract:
In this paper, A-B hybrid equation method is given. This method is different not only from high truncated spec-tral method, but also from amplitude evolution method. Dynamic problem in the baroclinic atmosphere may be transferred into complex Lorenz system by means of the method. Therefore, this method is an effective tool for stud-ying nonlinear bifurcation in wave-flow interaction. Meanwhile, it is of advantage to use this method, because it can overcome a lot of difficulties existing in high truncated spectral method and amplitude evolution method.
