![]() ![]() For example, from 1950 to 2015, tornadoes in Europe caused 4462 injuries, 316 fatalities and economic losses of at least EUR 1 billion ( Antonescu et al., 2016, 2017). tornadoes, downbursts, straight-line winds) can cause important disruption to socio-economic activity, including injuries or even fatalities, despite their local character compared to larger-scale mid-latitude synoptic windstorms or tropical storms. Meteorological phenomena associated with strong surface wind of convective origin (i.e. The application of methodologies such as the one presented here is necessary in order to build homogeneous and robust databases of severe weather cases and high-impact weather events. In those uncertain cases, the information resulting from this methodology contributed effectively to discern the phenomenon type thanks to the damage pattern analysis, particularly if no witness reports were available. ![]() This methodology has been applied by the authors in the past, sometimes only a few hours after the event occurrence and, on many occasions, when the type of convective phenomenon was uncertain. To synthesize the gathered data, three final deliverables are proposed: (i) a standardized text report of the analysed event, (ii) a table consisting of detailed geolocated information about each damage point and other relevant data and (iii) a map or a KML (Keyhole Markup Language) file containing the previous information ready for graphical display and further analysis. The methodology includes the collection of pictures and records of damage to human-made structures and on vegetation during the in situ visit to the affected area, as well as of available automatic weather station data, witness reports and images of the phenomenon, such as funnel cloud pictures, taken by casual observers. ![]() It is based on previous studies and also on 136 field studies performed by the authors in Spain between 20. ![]() tornado, downburst and straight-line winds). This paper presents a methodology to perform field surveys of damage caused by strong winds of convective origin (i.e. Moreover, evaluating the damage and characterizing its extent and intensity can be essential for further analysis such as completing a diagnostic meteorological case study. Post-event damage assessments are of paramount importance to document the effects of high-impact weather-related events such as floods or strong wind events. ![]()
