Meteorological Data Processing Methods in the Computer-Assisted ArtilleryMeteorology System (Battlescale Forecast Model)

摘要

The purpose of this report is to present basic information on the theoretical andpractical meteorological (met) principles employed in the Computer-Assisted Artillery Meteorology (CAAM) system using the Battlescale Forecast Model (BFM). CAAM (BFM) was designed to assimilate several types of met inputs, process these data, and produce artillery met messages, all on the battlefield. Central to this system is the use of a mesoscale atmospheric prediction model (the BFM). The introduction gives a history of the program and an overview of the design of CAAM. The model domain is described in terms of an area of operations and the data required to operate the model. Model initialization in terms of a three-dimensional objective analysis is described for two modes: with and without the input from a larger scale forecast model. The methods of the BFM are described in terms of initialization, nudging to the objective analysis, and the model forecast technique. The output of CAAM consists of two kinds of artillery computer met messages; these are derived from both the objective analysis and the BFM results. Finally, future improvements are mentioned.
