This paper describes the formulation and application of the nonhydrostatic Vorticity Model TVM which includes a third order piecewise parabolic advection scheme. Various types of topography-induced 2-D, hydrostatic and non-hydrostatic mountain wave cases, with different degrees of non-linearity were numerically simulated, and results compared to available analytical solution and/or results from other primitive equation mesoscale models. The 1972 Boulder windstorm was likewise simulated. Results for all simulations were obtained without any explicit diffusion, and with reduced resolutions, due to the characteristics of its PPM advection scheme.
