# List of case studies on tornadoes (2020–present)

This is a list of government or academic case studies on individual tornadoes or tornado outbreaks which occurred during the 2020s. A case study is an in-depth analysis which focuses on a single event, several events, and/or a specific aspect of an event.

## List

Case studies published by academia are included in this list. As part of the United States National Weather Service's (NWS) and Environment and Climate Change Canada's (ECCC) official duties, they are required to conduct a damage survey on every tornado in the United States and Canada. For this reason, only publications by the NWS and ECCC beyond a standard damage survey are included as, on average, over 1,200 tornadoes occur annually in the two countries together. Tornado records in Europe are kept by the European Severe Storms Laboratory (ESSL) in the European Severe Weather Database. For this reason, only publications by ESSL outside of the database are included.

| 2021 Quad-State Supercell | N/A | Researchers with the University of Nebraska–Lincoln published a detailed case study on the polarimetric radar observations obtained on the 2021 Quad-State Supercell, which produced 11 tornadoes, including two long-track, violent EF4 tornadoes. |
| 2021 Western Kentucky tornado | EF4 | A case study by Rebecca Freihaut with the University of Central Florida on how the residents of Mayfield, Kentucky recovered after the tornado. |
| 2021 Western Kentucky tornado | EF4 | A case study by researchers from Pennsylvania State University on how historic masonry structures in Mayfield, Kentucky performed during the tornado. |
| 2021 Western Kentucky tornado | EF4 | A detailed damage survey and analysis of part of the tornado's track, focusing mainly on Mayfield, Kentucky published by Timothy Marshall, a meteorologist, structural and forensic engineer; Zachary B. Wienhoff, with Haag Engineering Company; Christine L. Wielgos, a meteorologist at the National Weather Service of Paducah; and Brian E. Smith, a meteorologist at the National Weather Service of Omaha. In their conclusion, the researchers state, “the tornado damage rating might have been higher had more wind resistant structures been encountered. Also, the fast forward speed of the tornado had little ‘dwell’ time of strong winds over a building and thus, the damage likely would have been more severe if the tornado were slower.” |
| 2022 Arabi–New Orleans tornado | EF3 | Researchers with Auburn University, Florida International University, Pennsylvania State University, Louisiana State University, University of South Alabama, University of Illinois Urbana-Champaign, University of Kentucky, and CoreLogic, published an academic case study on how hurricane-resistant houses performed during the tornado. |
