A severe hail storm in complex topography in Switzerland - Observations and processes

Abstract: This paper studies a damaging hail storm that occurred on 6 June 2015 in the complex topography of Switzerland. The storm persisted for several hours and produced large hail resulting in significant damage.Storms of comparable severity occur on average only three times per year within the entire Swiss radar domain, but are rare events at this exact location, according to a set of over 400,000 automatically identified storms. A multitude of datasets, partly novel for central Europe, is now available to study th… Show more

“…On that day, blocking was present over the Scandinavian and Baltic Sea region (BS case; grey outline in Figure 7a), which was concurrent with a southwesterly to southerly mid-tropospheric flow over the investigation area. This flow direction is typical for central Europe, which supports the development of thunderstorms, as this pattern favours the advection of convection-favouring air masses towards central Europe (Kapsch et al, 2012;Merino et al, 2014;Wapler and James, 2015;Nisi et al, 2016;Trefalt et al, 2018;Piper et al, 2019). Air masses characterised by high values of equivalent potential temperature up to 320 K (not shown) were advected from southeastern Europe to eastern Germany resulting in unstable conditions (SLI values between −2 and −6 K; Figure 8a) and high atmospheric moisture content (PW values between 25 and 40 kg/m 2 ; Figure 8b), which are both conducive to widespread thunderstorm formation (see Greene and Clark, 1972;Manzato, 2003;Kunz, 2007;Mohr, 2013).…”

“…The role of complex terrain in triggering convection is widely acknowledged (e.g. Huntrieser et al, ; Davolio et al, ; Weckwerth et al, ; Nisi et al, ; Trefalt et al ., ). This study investigates not only thunderstorm initiation, but also HST initiation (Figure ).…”

“…Diversas pesquisas demonstram como são impactantes os efeitos da precipitação de granizo em culturas agrícolas, casas, carros, edifícios e na biodiversidade (KREUZ, et al, 2002;NIALL;WALSH, 2005;AMARANTE, 2009;VIANA et al, 2009;ALLEN et al, 2011;HAND;CAPPELLUTI, 2011;SILVA et al, 2012;MEZHER, 2012;KLANOVICZ, 2013;DOLATI et al, 2014;MOHR et al, 2015;PUNGE;KUNZ, 2016;BLAMEY et al, 2017;PUNGE et al, 2017;SANCHEZ et al, 2017;CALDANA et al, 2018;CAPOZZI et al, 2018;JIM et al, 2018;PREIN;HOLLAND, 2018;TREFALT et al, 2018). Como se trata, normalmente, de um evento local, a medição das ocorrências de granizo é dificultada pela baixa densidade de estações meteorológicas que detectam este fenômeno.…”
