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 Master Thesis work "Numerical analysis of shedding vortices past a simplified supercell storm" (2023) and to the submitted paper for Communications Earth&Environment journal "Revealing atmospheric Von Kármán Vortex Street past supercell thunderstorms" (2025).

"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.

本数据集包含借助OpenFOAM v9软件运行的大涡模拟（Large-Eddy Simulations）输出结果。本数据集关联2023年硕士学位论文《简化超级单体风暴尾流脱落涡旋的数值分析》，以及2025年投稿于《Communications Earth&Environment》期刊的论文《超级单体雷暴尾迹大气冯·卡门涡街揭示》。

文件"constant.tgz"内含模拟搭建所需的计算网格及其他恒定参数值。

文件"postProcessing.tgz"内含OpenFOAM软件生成的探针监测数据与水平截面提取数据；此外，该文件还按5分钟间隔记录了最大上升气流垂直速度的计算结果。

顾名思义，文件"initial_condition.tgz"内含模拟的时间0时刻数据，亦即初始条件。

文件"output_simulation_steady_state.tgz"内含用于分析的模拟输出结果（速度场、浮力场与气压扰动场），采样间隔为5分钟（300秒）。

前述输出场与计算网格可通过后处理可视化工具ParaView进行绘制，该工具是OpenFOAM输出结果可视化的标准软件包。
