The infrasound array at Piszkés-tető, Hungary (PSZI) has been operational since May,
2017. Since then PSZI has collected hundreds of thousands detections. These include
detections both from known and unknown sources. The categorisation of the detections
would be important for future automation. The objective of this study is to identify
and collect those detections that belong to local and regional storms and lightings.
We present a methodology to identify storms by correlating lightning data from the
Blitzortung database we consider as ground truth with the PMCC infrasound detections
at PSZI. We also analyse the seasonal variations in the directions and distances of
the detected storms.
