Numerical simulation of atmospheric von Kármán vortex street through Large-Eddy Simulation

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.
