Simulated hailstorms over Switzerland in May 2018 in current and future climate conditions

<p>Several remarkable hailstorms have occurred on the territory of Switzerland during the month<br>of May, 2018.<br>This period has been simulated, using the WRF4.0 model at a convection-permitting<br>resolution (1.5 km), using different microphysical schemes (Thompson, Morrison, P3).<br>The surrogate climate change approach has been used for imitating the climate conditions,<br>corresponding to the end of the 21st century (CMIP5 model data, RCP8.5 scenario).<br>The HAILCAST-1D model output has been used as a measure of simulated hail size and 5-<br>minute 3-D radar reflectivity field has been used for cell identification and tracking.<br>Hailstorms produced in the current climate and in surrogate climate change simulations have<br>been examined using neighborhood methods and a storm-tracking algorithm. Current-climate<br>simulated hailstorms were compared with the ground observations and MeteoSwiss radar<br>data.<br>The influence of microphysical schemes to the characteristics of simulated hailstorms has<br>been studied.&#160;</p>
