The first full version of the International Fujita Scale (IF Scale) has been published on 28 July 2023 and is available here.
When extremely severe weather happens in Europe, ESSL participates in damage surveys. Reports of these surveys can be found here:
- Report: The F4 tornado in Moravia on 24 June 2021
- Report: The F4 tornado in Northern Italy near Mira on 8 July 2015
- Attachment listing all recorded damages
- Attachment listing the method that was followed
A decision matrix for damage to plants, presented by Martin Hubrig at the ECSS2015, can be downloaded here (and here the abstract).
A draft report on “International Approaches to Tornado Damage Characterization” by Kopp et al. (International Tornado Working Group 2017) is available here.
