![]() ![]() The model experiments reveal that the development of the bow echo is particularly sensitive to the initial wind field and the lower-tropospheric moisture content. Operational numerical weather prediction models mostly failed to forecast the storm, but high-resolution regional model hindcasts enable a realistic simulation of the storm. This resulted in hurricane-force wind gusts (reaching 40 m s −1) along a narrow swath in the Rhine–Ruhr region leading to substantial damage. The synoptic and mesoscale analysis shows that the outflow of a decaying MCS above northern France triggered the storm, which exhibited the typical features of a bow echo like a bookend vortex and a rear-inflow jet. The key ingredients for the development of the Pentecost storm were the concurrent presence of low-level moisture, atmospheric conditional instability, and wind shear. Moreover, the forecast potential of the storm is evaluated using sensitivity experiments with a regional climate model. ![]() The synoptic-scale and mesoscale characteristics of this storm are analyzed based on remote sensing data and in situ measurements. This storm was one of the most severe thunderstorms in Germany in decades. On Pentecost Monday, 9 June 2014, a severe linearly organized mesoscale convective system (MCS) hit Belgium and western Germany. ![]()
