Abstract

The reliability of national tornado database is crucial for tornado research. Since 1990s, the WSR-88D radars network was setup and the quality of the data in the historical tornado database has been improved. We evaluated the reliability of the historical tornado data of the United Sates from 1950 to 2011 within three period of time, i.e., 1950-1964, 1978-1992, and 1997-2011. Specifically, the study adopts descriptive and fixed effects model to examine the effects of distance on the observed density of tornadoes. We found that the database has increased reliability overtime. But, the improvement is limited to areas that are close to radar site. The biases from underreporting tornadoes are still an issue and researchers should carefully examine this underreporting problem before using the database.
