MODEL-OUTPUT POST-PROCESSOR ALGORITHM DEVELOPMENT WITH INTERACTIVE VISUALIZATION SOFTWARE

An "interactive " algorithm development methodology for creating meteorological forecast products is described. Using interactive grid manipulation software, gridded model forecast parameters are compared to either human forecasts, or to actual verification data. Algorithms for desired weather elements are developed using the interac-tive software. Two such projects have been completed at the US Air Force Weather Agency (AFWA). Model output grids were combined to make severe weather forecasts and surface visibility forecasts. GrADS and IDL were the grid analysis software systems used to develop these algo-rithms. The interactive process and reasons for the success of this method of meteorological product algorithm devel-opment are discussed. 1
