Analyses of thunderstorm structures using data of a Ka-band Doppler polarimetric vertical cloud profiler

This study investigates the structure of strong convective storms to determine the difference between the structure of storms inducing or not lightning discharges. The structure of strong convective storms is investigated using a Ka-band Doppler polarimetric vertical cloud profiler operating at a frequency of 35 GHz. The profiler is located at the Milešovka meteorological observatory in Czechia (Central Europe). To study the structure of storms, we used the basic radar measurements of phase and power spectra of the co- and the cross-channel. We analysed the data from all the storms that occurred close to the Milešovka observatory during 2018-2022 and we performed statistical and correlation analyses of vertical profiles of phase and power spectra in the co- and the cross-channel in dependence on the distance of lightning discharges observed and recorded by the EUCLID lightning network.
