A Visual Observation of the 6 June 2005 Descending Reflectivity Core

Abstract

A visual observation of a descending reflectivity core (DRC) is presented in tandem with radar data from the Frederick, OK WSR-88D for a supercell storm that occurred on 6 June 2005. The DRC appeared as a dense column of precipitation to the right of the main core, west-southwest of the wall cloud. Through the use of stereo photogrammetric techniques, it is shown that these rain elements corresponded with a local maximum of reflectivity within the supercell echo appendage.
