Abstract: Numerical methods of calculating the pseudo-adiabatic characteristics of saturated air parcels are presented, based on the Rossby definition of the pseudo-equivalent potential temperature. With these methods it is then ...

Abstract: Numerical experimentation with various finite difference formulations of a particular set of differential equations incorporating a map scale factor indicates that the stability of the calculations is as dependent upon the ...

Abstract: An overview of the regularly scheduled sequence of computer analyses and forecasts produced at the National Meteorological Center (NMC) is presented. The available computer resources and time schedule constraints are ...
