Artillery Firing Accuracies for Project PASS Using the ARTY/GWC Method.

摘要

The ARTY/GWC method for providing meteorological messages for artillery firings was tested in this study. In this method, Global Weather Central (GWC) 18-hour prognostic fields are updated continuously using Army Corps upper-air soundings. This establishes a prognostic data base from which meteorological messages may be extracted when required. The testing of the method consisted of comparing actual and simulated cannon firings, using data from the artillery field experiments that were carried out at White Sands Missile Range in November and December of 1974. The accuracies of the simulated artillery firings using the ARTY/GWC method were not significantly better than those obtained using established techniques. However, improved accuracies with this method should be possible when prognostic products become available that are generated by numerical models designed to treat regions of limited size in more detail, particularly with regard to the boundary layer and mountainous terrain.
