CLOUDS OVER AMPHIBIOUS OPERATIONS

THIS PROPOSED STUDY WILL EXAMINE THE FEASIBILITY OF USING A EULERIAN LIMITED AREA MODEL (LAM) TO IMPROVE PREDICTION OF CHEMICAL, BIOLOGICAL, AND OBSCURANT CLOUDS DURING AMPHIBIOUS OPERATIONS. THE LAM HAS BEEN USED TO PREDICT MESOSCALE AND MICROSCALE METEORO LOGICAL PHENOMENA FOR A WIDE VARIETY OF CLIMATIC REGIMES AND HAS BEEN TESTED FOR A NUMBER OF EXTENSIVE METEOROLOGICAL FIELD EXPERIMENTS. THE LAM CAN PREDICT LOCALIZED THREE-DIMENSIONAL CIRCULATION AND ATMOSPHERIC DISPERSION CHARACTERISTICS IN THE VICINITY OF A SHORELINE LAND-SEA INTERFACE. THE STUDY WILL INCLUDE DEFINITION OF THE COMPUTER RESOURCES AND MEASUREMENTS DATA AVAILABLE FOR OPERATING THE MODEL SYSTEM. SPECIFICATIONS FOR A PROTOTYPE MODEL SYSTEM BASED UPON THE LAM WILL BE DEVELOPED. AN INTERACTIVE CLOUD MODEL WILL BE DESIGNED TO SIMULATE THE BEHAVIOR OF CHEMICAL, BIOLOGICAL AND OBSCURANT CLOUDS, UTILIZING THE METEOROLOGICAL CONDITIONS DEVELOPED BY THE LAM. THE LAM WILL BE USED TO SIMULATE A COASTAL LOCATION WITH REPRESENTATIVE METEOROLOGICAL CONDITIONS TO DETERMINE THE FEASIBILITY FOR SIMPLIFICATIONS. FULL REQUIREMENTS WILL BE SPECIFIED TO ALLOW MODERN SOFTWARE ENGINEERING TO START IMMEDIATELY IN PHASE II.
