**3. Results**

This section is divided into two parts. The first part describes a particular thunderstorm that occurred on 10 June 2019. We selected this thunderstorm because on that date, the observer recorded a thunder less than 1 s after he saw the lightning flash at the Milešovka observatory. According to geographical coordinates in EUCLID data, the lightning discharge occurred at a distance of only 65 m from the observatory. This lightning discharge was the second closest in our dataset; on 1 June 2018, there was a lightning detected directly at the observatory, which hit the observatory according to the book of records written by observers. Nevertheless, we do not detail this thunderstorm (on 1 June 2018) in this study since Sokol et al. [33] already studied it in detail.

Contrary to the first part of this section, which is dedicated to one particular thunderstorm, the second part of this section presents common characteristics, including LDR, that were typical throughout all thunderstorms that occurred in the 38 days in the dataset (Table 3). It presents results from the comparison of cloud radar data with lightning data in dependence on the distance of lightning discharge to the Milešovka observatory (i.e., NL vs. FL).
