Abstract : A detailed description of a program which produces cloud forecasts for periods of 12, 24, and 36 hours by Quasi-Lagrangian advection is presented. The principles on which the program is based are explained. Detailed presentations of the logic of each subroutine in the program are provided, along with descriptions of the specific numerical algorithms which are utilized. Program listings and flow diagrams are shown. Options for both extended core storage (ECS) and mass storage versions of the program are provided. Listings of both Varian output and for high quality, hard copy, grey-scale output are presented. Finally, sample output of the Varian and Muirhead output of the program are shown. (Author)
