Digital Doppler Radial Velocity Data Compared Objectively with Digital Reflectivity Radar Data.
Abstract
An investigation was conducted to determine the feasibility of objectively analyzing digital Doppler radial velocity data at constant altitudes. Data were supplied by the National Severe Storms Laboratory at Norman, Oklahoma. The study area was a 96 km by 116 km box surrounding the Chickasha, Oklahoma, synoptic network. A computer program, initially developed by Greene in 1971 and subsequently modified, was used as the basis for this computer program development. This research demonstrated that mesocyclones could be located using constant altitude radial velocity maps (CAVM) on a 2-km horizontal and a 1-km vertical grid scale without correcting for storm motion. However a 1-km horizontal and vertical grid scale was found to be 'optimum' for location and study of mesocyclones. Constant altitude velocity maps (CAVM) were then compared with constant altitude reflectivity maps (CAZM). This comparison, using two different storms, demonstrated that CAVM analysis was superior to CAZM analysis for the detection of severe storm areas.
