Abstract: The Battlescale Forecast Model (BFM) produces many forecasting parameters including temperature, pressure, dewpoint, relative humidity, wind information, as well as precipitation amounts. While these output data provide valuable weather information Tactical Decision Aids such as the Integrated Weather Effects Decision Aids (IWEDA) have a need for additional parameters such as icing and turbulence. The IWEDA generates current and forecasted impacts on approximately 70 weapon systems, such as attack helicopters and fixed wing aircraft, and personnel. Of most consequence to IWEDA, are the weather hazards on military operations. These hazards include three-dimensional (3-D) weather effects such as icing, turbulence, and clouds as well as several two-dimensional products that include surface visibility, fog, and thunderstoms. The raw output fields from the BFM and the MM5 can be used to derive these vital weather parameters.
