Abstract
Using the data captured by those complementary hail-dedicated observing systems, we review the hail activity in Switzerland during the period of interest (18 June to 31 July) and investigate two particularly intense hail days: 28 June and 8 July. One of the most promising research avenues is to investigate hailstone size distributions and temporal evolution using the sensor data, as this would enhance our general understanding of hail and could help to improve hail parameterization schemes in weather and climate models. Hail observations In the "Swiss Hail Network" project, 80 automatic hail sensors were installed between June 2018 and July 2020 in the three most hail-prone regions according to the climatology (Nisi I et al i ., [14], [13]; NCCS, [12]): the Jura, Napf Region and southern Ticino (Figure 1). Hail footprints and hail size measurements Figure 10(a) and (b) shows the radar hail footprints, the crowdsourced reports and the measurements of the automatic hail sensors for 28 June and 8 July, respectively.
