WSR-88D Example Products

Different radar data products can be displayed in a four-panel layout to assess storm structure. In the accompanying figure, the upper-left (upper-right) panel shows base reflectivity data at the 0.5 (7.5 degree) elevation angle, while the bottom two panels show the corresponding storm-relative velocity map (SRM) images. Thus, two different products at two different levels are displayed. Shown is an intense line of thunderstorms (bow echo) that raced across Hardin and Meade Counties in north-central Kentucky on May 14, 1995.  Widespread straight-line wind damage (winds up to 100 mph) and two embedded tornadoes resulted in these counties. A red-green couplet in central Meade County in low-level SRM data (lower left panel) signified a cyclonic (counterclockwise) circulation (mesovortex) associated with a brief tornado.
