Abstract:

Research was directed toward the development of new techniques to monitor and forecast the behavior of precipitation systems with Doppler weather radar. Focus was on the characterization of precipitation fields and of associated wind fields. Particular aspects that were examined are precipitation location, motion and type, synoptic scale and gust fronts, and the characterization of hurricane physical and kinematic structure. All analysis and forecast techniques are appropriate for a real-time operational environment. In addition, research has been completed toward the archiving and analysis of data from a wind profiling radar system. Efforts involved the definition of management, quality control, transformation, perusal, and extraction techniques for the profiler data. Also, techniques were developed to evaluate the meteorological conditions contributing to observed differences between the Loransonde and profiler wind estimates.
