Data accompanying the paper "Regime-dependent turbulence length scale formulation for NWP models based on turbulence kinetic energy, shear and stratification", submitted to Monthly Weather Review

This repository contains the outputs of MicroHH LES (van Heerwaarden et al., 2017) and ALADIN-CZ single-column model simulations of four idealized cases: 1) The continental cumulus case utilizing measurements from the Atmospheric Radiation Measurement (ARM) program, and Cloud and Radiation Testbed (CART) site in Oklahoma (Brown et al. 2002; Lenderink et al. 2004) 2) The trade wind cumulus case from the Barbados Oceanographic and Meteorological Experiment (BOMEX; Siebesma et al. 2003) 3) A drizzling stratocumulus case based on the first research flight data of the second period of the Dynamics and Chemistry of Marine Stratocumulus (DYCOMS-II) campaign (Stevens et al., 2005) 4) A stable planetary boundary layer case based on the Global Energy and Water Cycle Experiment (GEWEX) Atmospheric Boundary Layer Study (GABLS1) data (Beare et al. 2006; Cuxart et al. 2006; Holtslag 2006) The MicroHH LES outputs are taken from Reilley et al. (2022) study and can be also found at https://doi.org/10.5281/zenodo.6372434. Additionally, we provide case study outputs from the ALADIN-CZ 3D NWP model, wherein the fields roughly match those verified/shown in Fig. 9. The files are organized in the following way: 1) MicroHH LES model configuration files (.ini) and output files (NetCDF format) are stored in the file "LES.zip" within "conf" and "data" folders, respectivelly. Additionally, a sample script to plot LES-derived Turbulence Length Scales (TLS) and those based on NWP formulations (using LES data as input) is provided (plot.py). 2) The vertical profiles of (i) conserved variables and (ii) turbulent fluxes from the ALADIN-CZ single-column model for four idealized cases are provided in the file "single-column_simulations.zip", consisted of individual ASCII files (per case and TLS formulation). A detailed description of its content can be found in the associated README file. 3) Chosen surface and upper-air fields for (i) 23 November 2019 inversion and (ii) 24 June 2022 mesoscale convection system cases are provided in the file "case_studies.zip" and consisted of individual GRIB files per field and prognostic hour. A detailed description of its content can be found in the associated README file.本仓库收录了MicroHH大涡模拟（Large Eddy Simulation, LES，van Heerwaarden等人，2017年）与ALADIN-CZ单柱模式针对四类理想工况的模拟结果： 1) 采用美国俄克拉荷马州大气辐射测量（Atmospheric Radiation Measurement, ARM）项目及云和辐射试验场（Cloud and Radiation Testbed, CART）观测数据的大陆积云工况（Brown等人，2002年；Lenderink等人，2004年） 2) 源自巴巴多斯海洋与气象试验（Barbados Oceanographic and Meteorological Experiment, BOMEX）的信风积云工况（Siebesma等人，2003年） 3) 基于海洋层积云动力学与化学第二期试验（Dynamics and Chemistry of Marine Stratocumulus, DYCOMS-II）首架次研究飞行数据的降水性层积云工况（Stevens等人，2005年） 4) 基于全球能量与水循环试验（Global Energy and Water Cycle Experiment, GEWEX）大气边界层研究（Atmospheric Boundary Layer Study, GABLS1）数据集的稳定行星边界层工况（Beare等人，2006年；Cuxart等人，2006年；Holtslag，2006年） 本数据集所用的MicroHH大涡模拟结果源自Reilley等人（2022年）的研究，也可通过链接https://doi.org/10.5281/zenodo.6372434获取。此外，本仓库还提供了ALADIN-CZ三维数值天气预报（Numerical Weather Prediction, NWP）模式的工况模拟结果，其输出场与图9中验证/展示的结果基本一致。 本仓库的文件组织方式如下： 1) MicroHH大涡模拟模式的配置文件（.ini格式）与输出文件（NetCDF格式）分别存储于压缩包"LES.zip"内的"conf"与"data"文件夹中。此外，附带示例脚本plot.py，用于绘制大涡模拟得到的湍流长度尺度（Turbulence Length Scales, TLS），以及以大涡模拟数据为输入、基于数值天气预报模式参数化方案得到的湍流长度尺度。 2) 针对四类理想工况，ALADIN-CZ单柱模式输出的（i）守恒变量与（ii）湍流通量垂直廓线均存储于"single-column_simulations.zip"压缩包中，包含按工况与湍流长度尺度参数化方案分类的独立ASCII文件。其内容的详细说明可参见配套的README文件。 3) 针对（i）2019年11月23日逆温工况与（ii）2022年6月24日中尺度对流系统工况，选取的地面与高空场变量存储于"case_studies.zip"压缩包中，包含按变量与预报时效小时分类的独立GRIB格式文件。其内容的详细说明可参见配套的README文件。
