We thank Drs. Christian Keil, Axel Seifert, and Ulrich Schättler for their help whenever technical problems were encountered. Professor H.-D. Betz kindly provided the LINET data. The computational resources were provided by the German Weather Service (DWD), which is gratefully acknowledged. Also, we thank the two anonymous reviewers for their careful comments and the Convective Storms Group (NCSU) for their support during the preparation of the manuscript. This study was funded by the DLR project “Wetter und Fliegen.”
