Atmospheric Flow Modeling in Complex Terrain. JANNAF Safety & Environmental Protection Subcommittee Workshop Held in Vandenberg AFB, California on 26-27 September 1986

摘要

The subject of this workshop was to assess the current capabilities to model atmospheric flow in complex terrain. Emphasis was placed on Vandenberg Air Force Base, California, since it is one of the most complex areas being modeled and because of its operational importance. Also, Vandenberg is a good measure of current capabilities, since success in modeling this area would mean almost certain success with any area. Topics included: DoD flow modeling--A historical perspective; Incorporation of the critical streamline and mass-conservation principles in an efficient 3-d wind interpolation model; Physical assumptions in flow modelling and their effect on model performance; Description of the Meteorological and Range Safety Support (MARSS) system; Technology development for a computerized propellant hazard response protocol system; Modeling airflow over variable terrain; The REEDM wind flow model; Mean flow in Vandenberg terrain--Experimental results; Evaluation of a surface-layer windflow model for complex terrain using meteorological tower data from Vandenberg; Atmospheric models applied to Vandenberg terrain; Principal component analysis of the vector mesoscale wind field at Vandenberg AFB.
