Similarities and Differences Between Thunderstorm Outflows Measured in Italy and Romania
摘要
Do thunderstormsThunderstorm thatThunderstorm outflows occur in different parts of the world possess similar characteristics? The answer to this question will have great significance on the design of structures exposed to thunderstorm windsThunderstorm winds, as well as on the understanding of the atmospheric variability of the phenomenon based on the location of occurrence. This paper is an initial attempt to clarify aspects related to similarities and differences between thunderstorm outflowsThunderstorm outflows measured in Italy and Romania. For this a datasetDataset of 29 Italian and 18 Romanian records are used. Comparison is made in terms of visual resemblance of velocity time series, outflow characteristics and noteworthy velocity ratios. Results show striking resemblances of 10 min, 1 h, and 10 h thunderstormThunderstorm records measured in the two different sites, which seems to suggest that thunderstorm outflowThunderstorm outflows characteristics can be the same at least in the Mediterranean and continental part of Europe. This is clearly noteworthy in the perspective of assuming a standard model of thunderstorm outflowsThunderstorm outflows for civil engineering purposes.
