An Evaluation of Three-Dimensional Weather Hazards Using Sounding Data and Model Output Data.

Report No. ARL-TR-1046
Authors: Jeffrey E. Passner
Date/Pages: August 2000; 52 pages
Abstract: The Atmospheric Sounding Program (ASP) is initialized by upper-air observations, either from standard rawinsonde observations (RAOB)s or output from a numerical model, the Battlescale Forecast Model (BFM). These data are decoded and processed before calculations are performed, giving the forecaster an overview of the atmospheric conditions at or near the ROAB launch site or the BFM grid point. The ASP uses these data to produce a series of weather-hazard products that can be used for analysis or forecasting to 24 h from the initial time of the BFM run. Included in these weather hazards are turbulence, icing, and clouds - three parameters, which have major influence in military operations.
