From April to September severe thunderstorms regularly affect Switzerland. Wind gusts and hail may cause substantial damage and represent high costs for insurance companies. Switzerland is a perfect laboratory for hail research, because it has a complex topography and because of its exceptional hail data base.
Data from the five polarimetric C-Band radars of Switzerland, crowdsourcing hail reports from the MeteoSwiss App and measurements from 80 automatic hail sensors are being analysed statistically to improve short-term hail predictions (so called hail nowcasting) and to better understand meteorological processes that lead to hail and strong wind gusts.
