The CAPE index is the one of most commonly used convection indicators. The research was based on a re-analysis from the NCEP/NCAR database, soundings and two atmospheric circulation classifications: Grosswetterlagen and T. Niedźwiedź. The research period included 13 years from 2000 to 2012 during which time the maximum CAPE value reached 3695 J/kg (derived by reanalysis) and almost 4450 J/kg (derived by sounding). According to Grosswetterlagen, the biggest average and maximum CAPE values over southern Poland occurred during three synoptic situations: Trough over Western Europe (TRW), Low over Great Britain (TB), Low over Central Europe (TM)polinfo:eu-repo/semantics/openAccessatmospheric circulationconvectionCAPEsoundingsArtykułhttps://doi.org/10.14746/bfg.2016.7.14
