Dynamical Behavior for the Three-dimensional Generalized Hasegawa-Mima Equations

We consider the following generalized three-dimensional (3-D) dissipative Hasegawa-Mima equations:

We consider the following generalized three-dimensional （3-D） dissipative Hasegawa-Mima equations： △ut - ut ＋ {u, △u} ＋ knuy - vz ＋ α△（u - △u） ＋ f（x, y, z） = 0, （1） vt ＋ {u, v} ＋ uz ＋ γv - β△v = g（x, y, z） （2） with initial datum v｜t=0=u0（x,y,z）,v｜t=0=v0（x,y,z）,（x,y,z）∈Ω∈R^3 （3）.
