We analysed strong convective events that were observed in summer 2018 at the observatory and were detected by the cloud radar, which read high reflectivity values. We applied our algorithm treating the radar data to retrieve vertical air velocity and five types of hydrometeors and we conducted a comparative study of the results with ground-based measurements of lightning. The study showed that hail and rain are the two hydrometeors, which clearly tend to be more frequent in convective clouds that are situated above the cloud radar, when a lightning is recorded in the vicinity of the Milešovka observatory. Similarly, in case of nearby lightning downdrafts are observed at lower altitudes (up to 4 km above the radar), whereas slight updrafts are more typical for higher altitudes above the radar.
