PhD-Project

My PhD project is about combining the following sources of observations to improve our understanding of hail:

  • (i) a recent network of 80 automatic hail sensors (project "The Swiss Hail Network") which record the precise timing of hailstone impacts, report the kinetic energy and estimate the diameters of individual hailstones.
  • (ii) the crowdsourcing function of the MeteoSwiss app which allows users to report the hail size category, time and location using their smartphone.
  • (iii) two operational hail products of the Swiss weather radar network: the probability of hail at the ground (POH) and the maximum expected severe hailstone size (MESHS).

After doing a case study of the intense and widespread hailstorms of summer 2021 in Switzerland, I'm currently analyzing the hail sizes and kinetic energies distribution from the automatic hail sensors network.
 

Research Focus

My research interests are the following: hail observations, climatology and nowcasting, convective storms, large-scale dynamics, data analysis, and temporal clustering of heavy precipitation.
