A barotropic and two- and three-layer baroclinic primitive equation prediction models are developed from a ten-layer model previously designed for short range forecasts in the tropics. Twenty-four predictions from the models are compared to evaluate any degradation in the forecasts as the vertical resolution of the models decreases. The barotropic primitive equation model on a global tropical grid is used to evaluate the possibility of using a numerical variational analysis as an initialization technique. Initialization of data with the nonlinear balance equation is used as a comparison. Author
