From: Thunderstorm charge structures producing gigantic jets

Common features of four gigantic jet producing storms. The top rows of each panel show horizontal elevation angle scans of base reflectivity, radial velocity, and spectrum width of the upper regions of the thundercloud (12–15 km). The bottom rows show vertical cross sections, along the white lines in the top row, for each radar variable. Radar and lightning data for the (a) Northeast FL storm on 28 September 201016 (b) South OK storm on 09 September 201016 (c) Southeast FL storm on 03 August 20137,8 and (d) Southcentral FL storm on 12 September 201411. VHF lightning mapping data of the discharge activity in the upper positive charge region leading to each gigantic jet is shown (when available) as white circles and NLDN IC events as black circles or black vertical lines. The attempted bolt-from-the-blue is shown as open white circles16. The white arrows in column 2 of each panel denote the direction pointing to the radar. Distance scales are listed in km.
