How Terrain Geometry and Environmental Instability Shape Precipitation in Mountain-Crossing Mesoscale Convective Systems
Description
The dataset was created to enable public access to the numerical simulation results used in the manuscript “How Terrain Geometry and Environmental Instability Shape Precipitation in Mountain-Crossing Mesoscale Convective Systems” by Fan Wu and Kelly Lombardo. This work was supported by the Atmospheric Radiation Measurement (ARM) User Facility (DOE Office of Science) under DE-SC0022913, and by the National Science Foundation under AGS-2002660. The files include model output from multiple numerical experiments described in the paper, designed to isolate the effects of terrain geometry and environmental instability on precipitation in mountain-crossing mesoscale convective systems. All the simulation data was output from Cloud Model 1 (CM1) version 20.3 and post-processed for plotting figures in our research article. Files in CTRL are the y-averaged simulation data for the control experiments initialized by the observed sounding from the Villa Dolores site (S1) at 0000 UTC on 15 March 2019 during the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign. In the CTRL files, various bell-shaped terrains were configured for the sensitivity of terrain geometry, including mountain width of 50, 100, and 150 km, and crest height of 2.0, 2.5, and 3.0 km. In the other set of sensitivity experiments of environmental instability, we tested initial CAPE values of 1500, 2000, 2500, and 3000 J/kg for each mountain geometry. The corresponding simulation data can be found in the folders of H20W50, H20W100, H20W150, H25W50, H25W100, H25W150, H30W50, H30W100, and H30W150, and each compressed file includes four netCDF files for the four different initial CAPE values. The folder named "Precipitation data" contains the post-processed rainfall data used to produce the figures in the paper. For more information or any questions about the data and our research, please contact Fan Wu (wufan.iap.cas@outlook.com) . Due to the limitation of upload (10 Gb), only precipitation data and CTRL were uploaded. More simulation data can be generated by the model and sounding data uploaded to the folder of Model.
