Abstract:

Studies have been made regarding the use of Doppler wind profiler data in weather analysis and forecasting. Wind profiler from the Fleming, CO and McAlevys Fort, PA sites were used to examine a number of cases of subtle weather situations. Use of the wind profiler data, together with conventional National Weather Service rawinsonde data proved quite helpful in understanding the cause of subtle weather systems seen in either satellite imagery or in the profiler wind variations. In addition to examining the profiler winds, studies were made of the utility of profiler-derived temperature gradients, temperature advections, and lapse rate gradient information. These quantities were derived from the observed vertical wind shears, assuming that the thermal wind relationship was reasonably valid. The framework is set forth for future studies involving profiler networks. Keywords Atmospheric temperature Weather forecasting VHF Dopper radar Meteorological fronts Jet streams Weather systems.
