The authors are grateful to the reviewers for helpful comments. The database in the present study was compiled as a part of the project entitled “A Study on Tornadoes and Downbursts,” which started as the first cooperative project among research departments in the Meteorological Research Institute (MRI). The first two authors are grateful to Dr. Y. Okamura, the former Director General of MRI, and the staff of the Planning Office, for their invaluable support for the initiation and fulfillment of the project. Data input into the database was carefully done by Mrs. K. Yoshiye. The database described in this paper may be provided to research scientists on a floppy basis upon request. Those who would be interested in the database, please write to the corresponding author.
The content of this paper was presented at the spring meeting of the Japan Meteorological Society (Niino et al. 1994), where the content of Hayashi et al. (1994b) was presented in the same session (Hayashi et al. 1994a).
