A-B Hybrid Equation Theory on the Feedback of the Basic Flow Modification on the Wave and Its Application
平均流变化对波反馈的A-B混合方程理论

Based on the two-layer model equations, the A -B hybrid equations are derived to describe the feedback of the basic flow modification on the wave amplitude. After being transformed into Lorenz system, the A -B equations are used to study the mechanism of the feedback of the basic flow on marginal wave, as well as their stability near the balance points in the phase space. It is a quite important complement to the E-P flux theory in wave-mean flow interactions. In addition, the potential applications of the A -B hybrid equation theory to the wave-mean flow interactions and convective systems are pointed out in this paper.
