Describes numerical solutions of Zakharov-type equations for lower-hybrid (LH) waves, including pumping at the long wavelengths and dissipation at short wavelengths in the form of dissipative cavitons. Quasistationary structure undergoing many sequences of collapse due to dissipation; Ion-wave interactions; Possibility of trapping of short-wavelength LH oscillations.

Proposes an analytical model of the tilting instability that exhibits inverse cascade phenomenon, conserving both energy and enstrophy. View that tilting instability is an instability of convective motions two-dimensional ideal fluid transforming convection into sheared flow; Evolution of the nonlinear stage in which initial fluid convection is transformed completely into the large-scale flow.
