Book excerpt: This study examines the capability of the Gust Front Detection Algorithm (GFDA) developed for the Terminal Doppler Weather Radar (TDWR) system to detect other types of non-gust front weather phenomena which are associated with patterns of convergence in a Doppler-radar radial velocity field. The potential use of the GFDA as a nowcasting tool, a mesoscale forecasting tool, and as a tool to detect other kinds of aviation hazards besides gust fronts, needs investigation. The phenomena studied include synoptic fronts, sea-breeze fronts, gravity waves, terrain-induced convergence boundaries, old thunderstorm outflow boundaries, and the convergence bands within extratropical cyclones associated with enhanced precipitation. Comparisons of the convergent characteristics of these other phenomena to those of gust fronts are made. In addition, several case studies are presented to demonstrate the ability of the GFDA to detect the non-gust front phenomena.
