Abstract
Near Denver on July 11 1988, a moderate-reflectivity thunderstorm produced a microburst of unusual intensity during the test operation of the Terminal Doppler Weather Radar (TDWR) system. This microburst-producing storm, unlike those previously investigated, contained a complex updraft structure and an intense microburst downstream from the main precipitation shaft. Of special significance is that several successive airliners inadvertently encountered the microburst during final approach to Stapleton Airport. This paper focuses on the numerical investigation of this storm-via simulation with the Terminal Area Simulation System (TASS). Evolution and structure of the storm, including hazard indices based onF-factor, are presented and compared with “observed” data, including that measured by Doppler radar and aircraft flight data recorders.
