Abstract:

Storm Movement Prediction SMP is a proposed future product for Terminal Doppler Weather Radar TDWR, aiding controllers by tracking storms approaching and passing through the terminal environment. Because the scan strategy data acquisition of TDWR has been critically designed to meet the needs of its primary function, which is the detection of hazardous low-altitude wind shear, there is the question of whether reliable storm tracking can be obtained from the TDWR data set. The objectives of storm tracking involve a scope spatial range much larger than that required for the wind-shear algorithms where volume coverage is confined in off-airport sited radars to a sector covering the important approach and departure corridors and the only 360- degree scans are near-surface scans for gust-front detection. This report examines the application of a correlation based method of detecting storm motion, testing the notion that reliable storm motion can be inferred from existing TDWR data. In particular, storm motion derived from an analysis of the TDWR Precipitation product PCP is studied. A summary description of the algorithm is presented along with an analysis of its performance using data from MIT Lincoln Laboratorys TDWR testbed operations in Denver 1988 and Kansas City 1989.
