摘要：

A combined analysis of data from a C-band polarization diversity Doppler radar and a 3D VHF interferometric lightning mapping system is presented for the 21 July 1998 EULINOX supercell thunderstorm. Its lower positive charge center emitted much more VHF radiation than expected from the well-known tripole concept. In higher cloud regions VHF activity was sometimes linked to distinct levels, but their height varied strongly within the Cb-cell during its evolution. In early stages the supercell showed moderate VHF activity in reflectivity regions near 30 dBZ. In later stages VHF activity rose considerably and was linked to higher reflectivity factors of 40 to 50 dBZ. (C) 2000 Elsevier Science Ltd. All rights reserved.
