Abstract

The U.S. Air Force conducted extensive meteorological and tracer transport field experiments at Vandenberg Air Force Base (VAFB), California, May 9-29, 1997. The purpose of the campaign was to collect data for model verification studies. Rawinsondes were launched routinely at the site at time intervals that varied from two to four hours. We used the winds, temperatures, and mixing ratios of water vapor from soundings to initialize the variables and provide boundary conditons for a state-of-the-art three-dimensional forecast model HOTMAC (Higher Order Turbulence Model for Atmosperic Circulation). Prelminary simulations were conducted over the computational domain of 92 km in the east-west direction and 94 km in the north-south direction. The meteorological simulation started at 0300 1st (loca
