We investigate the stability of a shear flow in a stratified fluid. The flow is assumed to be inviscid and Boussinesq and the base state density gradient is vertical with constant Brunt-Vaisala frequency. The shear is taken as horizontal, where the base-state velocity has uniform direction and it's magnitude depends on the transverse horizontal coordinate, U(y). Unlike vertical shear flows, this combination of horizontal shear with vertical stratification is inherently three-dimensional and Squire's theorem is inapplicable. Spatial stability characteristics are obtained using the normal-mode approach and the Riccati transform. Sensitivity of the stability characteristics and their qualitative features are investigated by numerical methods for free-shear flow approximated by the hyperbolic tangent.
Keywords: Spatial stability, unstable shear flow., Riccati equation, horizontal shear flow.
