A New Tornado Map for the United Kingdom and Ireland 1054-2025

A new tornado map for the United Kingdom and Ireland has been created for the years 1054-2025. This builds on an initial map which was first produced and published by the Tornado and Storm Research Organisation (TORRO) in 2015. Therefore, after a decade of receiving much new and also revised information, especially from detailed site investigations and updated historical data, this map presents a valuable contribution to better understanding tornado climatology. The United Kingdom is the only country in the world with a record of tornadoes (and waterspouts) for some 971 years. Presenting these tornadic events spatially with reference to intensity and seasonality allows the reader to infer much useful information. This presentation will examine the events, trends and hotspots. It will examine regionality, bias, and historical reporting along with presenting a striking visual of tornado climatology for the United Kingdom and Ireland.

TORRO was established in 1974 (www.torro.org.uk) as a privately-supported research body serving the national and international public interest. TORRO would like to thank the hundreds of members and site investigators who have contributed to the quality of the database over the last 50 years. Key contributors to this ongoing effort have been Terence Meaden, Mike Rowe and Paul Brown, Peter Kirk (data analysis) and John Tyrrell (Ireland events). Special contribution has been made by Tim Prosser for the map creation, where full credit should be given.
