Simulation datasets for: Intense surface winds from gravity wave breaking in simulations of a destructive macroburst

Shortly after 0600 UTC (midnight local time) 9 June 2020, a convective line produced severe winds across parts of northeast Colorado that caused extensive damage, especially in the town of Akron. High-resolution observations showed gusts exceeding 50 m s−1, accompanied by extremely large pressure fluctuations, including a 5-hPa pressure surge in 19 s immediately following the strongest winds and a 15-hPa pressure drop in the following 3 min. Numerical simulations of this event (using the WRF Model) and with horizontally homogeneous initial conditions (using Cloud Model 1) reveal that the severe winds in this event were associated with gravity wave dynamics. In a very stable postfrontal environment, elevated convection initiated and led to a long-lived gravity wave. Strong low-level vertical wind shear supported the amplification and eventual breaking of this wave, resulting in at least two sequential strong downbursts. This wave-breaking mechanism is different from the usual downburst m..., This dataset includes the information required to reproduce the model simulations presented in the manuscript. This includes the namelist and initial and lateral boundary conditions for the WRF simulation, and the namelist and initial sounding for the CM1 simulation., , # Simulation datasets for \"Intense surface winds from gravity wave breaking in simulations of a destructive macroburst\"

Included here are the files required to configure and reproduce the numerical simulations presented in this manuscript. (Full model output is not included owing to its large size.) The manuscript includes simulations from the Weather Research and Forecasting model, version 4.0.3 () and Cloud Model 1 (), version 20.1.

## Description of the Data and file structure

For the WRF model, included are the 'namelist.input' configuration file, along with the 'wrfinput' files (netCDF format) for domains 1 and 2 that contain the model initial conditions. Also included are the time series output (plain text) for the locations shown in the manuscript, along with the configuration file 'tslist' for outputting these time series.

For the CM1 model, the 'namelist.input.cm1' configuration file and 'input_sounding' files are included, which can be used to initialize the model. Th...
