Different Initialization Data and the Performance by the BFM
ABSTRACT
The U.S. Army Research Laboratory supports the forecaster by producing weather forecasts on the Integrated
Meteorological System (IMETS). On IMETS, a mesoscale model known as the Battlescale Forecast Model (BFM) outputs
many weather parameters, including temperature, pressure, dew point, relative humidity, and wind speed. Additionally, many
other elements, such as icing, turbulence, clouds, and visibility, are produced in the post-processor. This report investigates
how these model outputs are influenced by the initial data that the model incorporates. These influences are studied by
evaluating the model’s temperature, wind, moisture, and cloud forecasts from 0 to 12 h after model base time. In this study,
two different models are used to initialize the BFM: the Pennsylvania State University/National Center for Atmospheric
Research Mesoscale Model Version 5 and the Naval Operational Global Atmospheric Prediction System model. The results
are discussed in this report.
