    Opis:
    This paper presents an analysis of the derecho phenomenon that occurred over Poland on August 11, 2017. The storm caused 6 fatalities, 39 injuries (Mańczak et al. 2022), and some of the greatest damage in the history of Polish forestry. Our study is based on radar meteorology and measurements from the Polish POLRAD radar network, and intended for advanced meteorologists with good knowledge of radar measurements. The research used both standard and specialized radar products as well as classic and Doppler scan data. The Doppler velocity products were especially useful for showing the characteristics of the storm. The analysis was mainly based on data from two radars: Poznań and Gdańsk, but the composite maps, consisting of data from more than one radar, were also analyzed. The derecho complex developed from unorganized thunderstorm cells over SW Poland and moved toward the NE. The various stages of the evolution of the system are presented and analyzed, accounting for the formation of a SC, the development of a rear inflow jet (RIJ), the split of the entire system, and the appearance of the bow echo signature. Significant factors affecting the scale of the wind damage were: (1) the extensive mesocyclone which evolved to the mesoscale convective vortex (MCV), and (2) a strong rear flank downdraft interacting with the rear inflow jet (RIJ).

    Opis:
    On average, a derecho occurs once a year in Poland while bow echoes happen several times per year. On 11 August 2017, severe meteorological phenomena were observed in Poland, including extremely strong wind gusts. We focused especially on the convective windstorm of a derecho type which occurred on that date in northern and north-western Poland. A rapidly moving mesoscale convective system (MCS) resulted in a bow echo, a mesoscale convective vortex (MCV), and finally fulfilled the criteria for a derecho. To establish whether our operational models in the Institute of Meteorology and Water Management, National Research Institute (IMGW-PIB) could reproduce a derecho of such intensity as that of 11 August 2017, the results from two mesoscale numerical weather prediction models were analyzed. The Application of Research to Operation at Mesoscale (AROME) and the ALADIN & AROME (ALARO) models were applied in the non-hydrostatic regime. We also examine how models differ with respect to mesoscale convective system drivers (such as vertical wind shear and convective available potential energy) and representation of deep convection (e.g., vertical velocities, cold pool generation). Forecasts are compared with observations of wind gusts and radar data. Severe weather phenomena, such as rear inflow jet and cold pool, were predicted by both models, visible on the maps of the wind velocity at 850 and 925 hPa pressure levels and on the map of air temperature at 2 m above the ground level, respectively. Relative vorticity maps of the middle and lower troposphere were analyzed for understanding the evolution of MCV.
