Abstract
The stability of a stratified parallel flow varying in two directions of an incompressible conducting fluid permeated by a uniform aligned magnetic field is investigated. Complex wave speed of an unstable mode lies in the upper half of a semi-circle whose diameter decreases with increasing magnetic field. It is also found that a strong enough magnetic field can completely stabilize flows with unstable density stratification.
