英文摘要	Lightning is one of the most dangerous natural phenomena, able to produce high impacts and damage on human beings and infrastructures (civil, electric, telecommunications, etc.) even though perception of it as a hazard is low. The aim of this study is to provide a detailed analysis of lightning occurrence throughout the Italian territory to support the work of different operators and researchers (physicists, meteorologists and electric/ITC engineers) improving knowledge about the main properties of lightning. Thus, an in-depth study of the statistics of lightning activity across the Italian territory for the period 2010–2019 is performed in detail using the data collected by the Italian Lightning Detection Network SIRF (Sistema Italiano Rilevamento Fulmini), part of the European network EUCLID (European Cooperation for Lightning Detection). This analysis presents general properties such as Ground Stroke Density (GSD) and the positive to negative strokes ratio by highlighting how seasonal, geographical and orographic factors influence their values. Then, attention is focused on lightning peak current, on flash multiplicity and on the distance between the points of impact of different strokes within a flash. Comparison made with other articles available in the literature reveals good agreement with studies conducted with other LLS data in Mediterranean regions. On the other hand, some differences appear with direct current measurements that can be partly ascribed to Lightning Location System (LLS) detection contamination (confirming other comparative studies of LLS and instrumented tower findings), to differences between tower and ground measures, and to the presence of regional differences. © 2021 Elsevier B.V.
