Tropical cyclone tornado records for the modernized National Weather Service era

Each specific tropical cyclone (TC) tornado record has been extracted from the broader Storm Prediction Center tornado database, for all Atlantic and Gulf of Mexico TCs to affect the continental United States from 1995-2009. The tornado records were analyzed individually to determine their presence within the circulation envelope of either a classified or remnant tropical cyclone, without regard to fixed radii from TC center, inland extent, temporal cutoffs before or after landfall, or other such arbitrary thresholds that may either exclude TC events or include non-TC tornadoes unnecessarily. Unlike other climatologies previously published in the literature, the chosen time period for this examination essentially covers only the full national deployment of the WSR-88D radar network. This permits consistent comparisons of a very large sample size of TC tornado events (>1100) during the era of modernized National Weather Service warning and verification practices. Tornado records will be analyzed and presented for individual storms, entire seasons, damage ratings, GIS- and cyclone-based distributions, path tendencies, and temporal trends.
