The bulk of this research was conducted while the first author was at Colorado State University and was supported by the National Science Foundation and the National Aeronautics and Space Administration under the respective Grants ATM 9618684 and NCC5-288 SUPP 0002. The remainder, conducted while the first author was at the National Severe Storms Laboratory working under D. P. Jorgensen, was supported through an associateship awarded by the National Research Council.
Profiler data and code to read them are from S. B. Trier and C. F. Shih of the National Center for Atmospheric Research (NCAR); WSI's NOWrad radar reflectivity is from the Global Hydrology Resource Center; and GCIP/ESOP-96 data are from the Joint Office for Scientific Support of the University Corporation for Atmospheric Research and the National Oceanic and Atmospheric Administration (NOAA).
