- Source: List of tornado outbreaks by outbreak intensity score
In late 2023, American meteorologist and tornado expert Thomas P. Grazulis created the Outbreak Intensity Score (OIS) as a way to rank tornado outbreaks. For the score, only significant tornadoes are counted: F2/EF2 tornadoes receive 2 points each, F3/EF3 tornadoes receive 5 points each, F4/EF4 tornadoes receive 10 points each, and F5/EF5 tornadoes receive 15 points each. The number of total points determine the rating for the outbreak, which is broken up into seven categories.
List
= Super Outbreaks
=There have been three tornado outbreaks which scored more than 250 points on the OIS, reaching the status of "Super Outbreak".
= Historic Outbreaks
=There have been 43 tornado outbreaks which scored at least 120 points, but less than 249 on the OIS, reaching the status of "Historic Outbreak".
= Devastating Outbreaks
=There have been several tornado outbreaks which scored at least 80 points, but less than 120 on the OIS, reaching the status of "Devastating Outbreak".
= Major Outbreaks
=There have been several tornado outbreaks which scored at least 30 points, but 79 or less on the OIS, reaching the status of "Major Outbreak".
