BALLISTIC WINDS STUDY
Abstract
The overall objective of this study is to continue work begun to investigate the improvement of an integrated ballistic message from multiple stations and the effects of mountainous terrain on space and time variability of meteorological measurements. One of the initial steps carried out during this reporting interval was the preparation of a detailed work plan for the contract year. The plan divides the technical work into five tasks: (1) CRAM modifications and tests; (2) ballistic winds evaluation; (3) withheld data experiments; (4) stability experiments; and (5) prediction techniques. The plan is contained in this report. During the first year of study an objective analysis program, the Conditional Relaxation Analysis Method (CRAM), was developed and applied as a tool for investigation. Under the first task, modifications and improvements to CRAM are presently being carried out. As a part of the second task (ballistic wind evaluation) residual errors (deflection) based on station observations along with those from Ft. Huachuca have been derived and are contained herein. In general, one does not find residual errors increasing as distance increases. The minimum residual error occurred only 2 times in 24 test firings at the station closest to the firing--Ft. Huachuca. On the other hand, the minimum residual error occurred 8 times 50 km to the west southwest, at Nogales.
