FORECASTING MIDDLE CLOUDINESS AND PRECIPITATION AREAS BY NUMERICAL METHODS

Abstract

A numerical prediction model suitable for computation using large-scale digital computers to forecast amounts of middle cloudiness, areas of precipitation, and precipitation amounts is presented. The model described use products derived from an operational Joint Numerical Prediction Unit forecast model. Background information, certain mathematical equations, and input-output format are presented. Figures showing a sample series of prognostic charts are presented. Results, limitations, and future prospects are discussed.
