文摘

Low-frequency tornado days became less common between 1974 and 2015. High-frequency tornado days became more common between 1974 and 2015. The variability of the number of tornadoes per tornado day increased between 1974 and 2015 more than the mean number. Tornadoes that occur on high-frequency days tend to be located further east than those that occur on lower-frequency days.
