title: Coupled atmosphere-wave-ocean simulation of Hurricane Dorian (2019)

description: <strong>Description</strong> This dataset provides the output of the coupled atmosphere-wave-ocean simulation of Hurricane Dorian from August 29 to September 7, 2019. The simulation is a composite of two separate simulations: From 00 UTC August 29 to 00 UTC September 1, 2019 From 00 UTC September 1 to 00 UTC September 7, 2019 The first simulation serves as "spin-up" for the hurricane and its environment prior to landfall. The second simulation is initialized from the output of the first simulation, while relocating the Dorian vortex to its correct position on September 1. Due to the size of the dataset only the surface fields are made available. <strong>Model configuration</strong> <strong>Atmosphere</strong>: Weather Research and Forecasting (WRF, https://github.com/wrf-model/WRF) model v4.2.2, with the Advanced Research WRF (ARW) dynamical core. The model has a 3-km resolution grid over the parent domain and a 1-km resolution nest over the Bahamas region (September 1-7 only), both with 45 vertical layers. Initial and boundary conditions are based on 6-hourly ERA-5 dataset. <strong>Ocean Waves</strong>: University of Miami Wave Model (UMWM, https://umwm.org). The model is configured at the same 3-km as the atmosphere model, and has 36 directional bins and 37 frequency bins that are logarithmically spaced from 0.0313 to 2 Hz. <strong>Ocean Circulation</strong>: HYbrid Coordinate Ocean Model (HYCOM, https://github.com/HYCOM) v2.3.01, configured at 0.01 degree resolution and 41 vertical layers. Initial and boundary conditions are based on daily GOFS 3.1 41-layer HYCOM + NCODA Global 1/12° Analysis, daily. K-Profile Parameterization for vertical mixing. <strong>Coupling</strong>: Earth System Modeling Framework (ESMF, https://github.com/esmf-org/esmf) v8.0.1 <strong>File Description</strong> blkdat.input - HYCOM (ocean circulation) configuration file dorian2019_atmosphere_1km_2019090100.nc - Atmosphere at 1-km resolution dataset dorian2019_atmosphere_waves_3km_2019082900.nc - Atmosphere and waves at 3-km resolution dataset, Aug 29 - Sep 1. dorian2019_atmosphere_waves_3km_2019090100.nc - Atmosphere and waves at 3-km resolution dataset, Sep 1-7 dorian2019_ocean_1km_2019082900.nc - Ocean circulation at 1-km resolution dataset main.nml - UMWM (waves) configuration file namelist.input - WRF (atmosphere) configuration file regional.depth.[ab] - HYCOM (ocean circulation) bathymetry files regional.grid.[ab] - HYCOM (ocean circulation) grid files umwm.gridtopo - UMWM (waves) grid and bathymetry file wrfbdy_d01 - WRF (atmosphere) boundary conditions file wrfinput_d01.2019082900 - WRF (atmosphere) initial conditions file for parent domain on Aug 29 wrfinput_d01.2019090100 - WRF (atmosphere) initial conditions file for parent domain on Sep 1 wrfinput_d02.2019090100 - WRF (atmosphere) initial conditions file for inner nest on Sep 1 <strong>Coupled model source code</strong> The model source code has not yet been released. We plan to open source it upon publication of the paper describing the simulation. When the source code is released, we will add the link to this repository.
