SUMMARY by Frank Merceret (Jan 8, 2003)
The citation performed NE/SW racetracks at an altitude of about 9 Km from 18:00 to 20:30Z in a region of highly electrified anvil just east of Cape Canaveral. This anvil was associated with a thunderstorm complex that produced severe weather throughout Brevard County, including a tornado at KSC. Heavy rain from the system fell on the WSR-74C resulting in strong attenuation due to radome wetting, so WSR-88D data is used for the analysis. While in-cloud (as well as surface) fields were high throughout the period, there were cases of cloud entry and exit that may be useful for analysis of field decay with distance from cloud edge. There were also indications of penetration through or near charge centers or screening layers. High fields were always associated with box-averaged radar reflectivities > 5 dBz.
