“…It is known mostly for the intense wind gusts and small amount of discharges. Comparing results from our previous paper about supercell activity (Martynski et al, 2018), we can conclude that the supercell in the most active hour generated an almost equal amount of discharge to the MCS case during its whole life cycle. That indicates that the supercell generated at least two times more discharge than MCSs, although the strongest strokes are still produced by the huge cloud clusters.…”

“…Price, 2002;Cummer, 2004). In our previous work (Martynski et al, 2018), we analysed a supercell that occurred over Poland. In this paper, our main goal is to combine measurements from two autonomous systems, namely the ELF (extremely low frequency) Hylaty station and DEME-TER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) satellite that measures ELF and VLF (very low frequency) fields.…”

Abstract. Mesoscale convective systems (MCSs) are especially visible in the summertime when there is an advection of warm maritime air from the west. Advection of air masses is enriched by water vapour, the source of which can be found over the Mediterranean Sea. In propitious atmospheric conditions, and thus significant convection, atmospheric instability or strong vertical thermal gradient leads to the development of strong thunderstorm systems. In this paper, we discuss one case of MCSs, which generated a significant amount of +CG (cloud-to-ground), −CG and intracloud (IC) discharges. We have focused on the ELF (extremely low frequency; < 1 kHz) electromagnetic field measurements, since they allow us to compute the charge moments of atmospheric discharges. Identification of the MCSs is a complex process, due to many variables which have to be taken into account. For our research, we took into consideration a few tools, such as cloud reflectivity, atmospheric soundings and data provided by PERUN (Polish system of the discharge localisation system), which operates in a very high frequency (VHF) range (113.5–114.5 MHz). Combining the above-described measurement systems and tools, we identified a MCS which occurred in Poland on 23 July 2009. Furthermore, it fulfilled our requirements since the thunderstorm crossed the path of the DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) overpass.
