Analysis of the Dynamics and Microphysics of a Wet Downburst Case Using Dual-Polarization Radar Data 11 AM/NWC 4140 A significant, wet downburst affected Norman, Oklahoma, on 14 June 2011. Surface winds in excess of 35 m s-1 (>80 mph) and hailstones in excess of 4 cm diameter occurred during the downburst. The polarimetric S-band (~11.09 cm) […]

In 2003, the Storm Prediction Center (SPC) began post-processing the National Centers for Environmental Prediction (NCEP) Short-Range Ensemble Forecast (SREF) system to provide operational guidance on the prediction of lightning hazards across the contiguous United States.

A number of novel techniques to examine polarimetric radar data collected via PPI scans in a time-height format have been developed in recent years. Using primarily polarimetric radar data collected by WSR-88D radars, techniques such as quasi-vertical profiles (QVPs), range-defined quasi-vertical profiles (RD-QVPs), and column vertical profiles (CVPs) have been used to investigate the vertical structure of precipitating systems such as winter storms, mesoscale convective systems, and landfalling hurricanes.
