Abstract : The vertical discretization in a linearized baroclinic prediction model was analyzed by comparing various finite element and finite difference solutions following Jordan (1985). Modifications were made on Jordan's (1985) Galerkin finite element approximation for two staggered grids. Comparisons were made with the unmodified models (Jordan, 1985) and with finite difference approximations for the same two staggered grids. The models were run with four experiments. Most of the oscillations that occurred in the temperature profiles near the surface of the unmodified Galerkin finite element approximations disappeared following the modifications. Keywords: Numerical weather prediction models, Theses.
