The purpose of the present study is to present a climatology of stormy phenomena in the western part of Romania for the period 1991-2020. The climatological norm chosen is significant for current research due to the fact that the data available after 2010 are of high accuracy and can be integrated in other specialized studies in the fields of agriculture, civil engineering, energy and construction. In the study, observational data from the integrated meteorological system of aviation, satellite data and RADAR parameters were used to characterize the convective formations that produce these stormy phenomena. The choice of the western area of Romania is significant because the predominant zonal circulation brings moisture and conditioned unstable air into the researched area. It is also worth noting that stations from different orographic areas in the western part of Romania were chosen precisely to allow the performance of conclusive statistics for the entire research area. In this studio, the aero-synoptic situations that can trigger stormy phenomena were also taken into account outside of the late spring and summer season, a period specific to the manifestations of atmospheric instability. It was concluded that the transitional seasons present a high frequency of electrical discharges, and during the summer an increase in the duration of electrical discharges is noted.
