In numerical simulations of unstable flows the absolute or convective nature of the instability can be modified by numerical effects. We introduce a convective/absolute analysis of the dispersion relations associated with discretized operators. This analysis leads to conditions on the discretization

We show that for the P N -P N-2 spectral element method (SEM), in which the velocity and pressure are approximated by polynomials of order N and N -2, respectively, numerical instabilities may occur in Navier-Stokes simulations. These instabilities depend on the formulation of the convection operato
The linear stability of free-shear flows is governed by their dispersion characteristics. The dispersion relation can be obtained by integrating the Rayleigh equation. The integration process can be hampered by the presence of singularities within the domain of integration. A complex-domain contour
## Abstract A model is proposed for the development of a dry convectively unstable boundary layer capped by a stable layer; included are the effects of timeβdependent surface heating, the stability of the capping layer, subsidence and any degree of turbulent interfacial mixing. A differential equat
