Interrelation of Temperature, Pressure, Air Density, and Humidity

摘要

During military operations in Southwest Asia (SWA), Headquarters, U.S. Armament,Munitions and Chemical Command (AMCCOM), Picatinny Arsenal, New Jersey (AMSMC-QAN-P(D)), requested a usable compilation of meteorological equations on the interrelation of temperature, pressure, air density, and humidity. The Predictive Technology Branch of AMCCOM was appointed by the Director, Command Group, Mid-East Operations, as the coordinator for all activities involving the identification of weapon and ammunition limitations for AMCCOM materials deployed in SWA. These equations were to be used to help define the exposure environment of munitions and materials in SWA. From the equations developed in the report and the supplied computer program, most vapor pressure, humidity, air density, and altimetry computations can be accomplished. Results compare favorably with values in meteorological handbooks.
