The dataset contains the outputs of Large-Eddy Simulations run with the software OpenFOAM v9. The dataset is related to the submitted work to Monthly Weather Review "Revealing atmospheric Von Kármán vortex street past a severe thunderstorm" (2026). "constant.tgz" contains the computational mesh and other constant values used for the simulation setup. "postProcessing.tgz" contains the data extracted from the probes and on horizontal planes, as generated by the OpenFOAM software. Furthermore, maximum updraft vertical velocity is computed at intervals of 5 minutes. "initial_condition.tgz" contains, obviously, the time 0 of the simulation, i.e. the initial condition. "output_simulation_steady_state.tgz" contains the outputs of the simulations (velocity, buoyancy and pressure perturbation fields) used for the analysis, at intervals of 5 minutes (300s). The output fields and the computational mesh can be plotted through the post-processing and visualization tool ParaView, used as standard package for the visualization of OpenFOAM outputs.
