Abstract
The non-modal kinetic theory of the kinetic drift instability of plasma shear flows [Phys.Plasmas, 18, 062103 (2011)] is extended to the investigation of the long-time evolution of the hydrodynamic ion temperature gradient and resistive drift instabilities in plasma shear flow. We find, that these hydrodynamic instabilities passed in their temporal evolution in shear flow through the kinetic stage of the evolution. In linear theory, this evolution involves the time dependent, due to flow shear, effects of the finite Larmor radius, which resulted in the non-modal effect of the decrease with time the frequencies and the growth rates of the instabilities.
