Villas Bôas, Ana B.; Castelão, Guilherme P. (2020). Data from: Wave-Current Interactions at Meso and Submesoscales: Insights from Idealized Numerical Simulations. UC San Diego Library Digital Collections. https://doi.org/10.6075/J0X928V6

This collection consists of NetCDF files that contain model output from WAVEWATCH III (WW3) version 5.16 corresponding to all experiments analyzed by Villas Bôas et al. (2020). The data is composed of gridded outputs of the idealized WW3 runs described in Villas Bôas et al. (2020), where only the steady-state solution (last time step) of each run is saved.

The collection has three main directories:

1 - /synthetic:
All files under this directory tree correspond to gridded outputs of WW3 forced by synthetic currents. The grided variables available are:

cur: Surface current
hs: Significant wave height
dir: Mean wave direction
t0m1: Mean wave period
spr: Mean directional spreading

The files are named as follows:

K{spectral slope}A{divergence fraction}T{wave period}S{kinetic energy}_{WW3 variable}.nc

such that the ensemble of significant wave heights for experiments with the following parameters: spectral slope=3.0 (absolute value), divergence fraction (??=1.0), wave period=10.3 s, mean kinetic energy=0.01 m²/s², is saved in the file K3.0A1.0T10.3S0.01_hs.nc

The runs with synthetic currents are further organized in three subdirectories:

standard
This directory contains outputs from the experiments using the standard parameter space described in Table 1 in Villas Boas et al. (2020). Spectral slopes = [-5/3, -2, -2.5, -3]; Divergence fractions = [0.0, 0.2, 0.4, 0.6, 0.8, 1.0]; wave periods = [7.0, 10.3, 16.6], mean kinetic energy = [0.01, 0.005]

alpha9
This directory contains outputs from experiments using divergence fractions equal to 0.9 and 0.95 that were used for Figure 5 in Villas Bôas et al. (2020).

double_energy
This directory contains outputs from experiments where the kinetic energy of the rotational flow was doubled by adding an equally energetic potential component, used for Figures 8 and 9 in Villas Bôas et al. (2020).

All realizations of a particular combination of parameters are collected in a single file along the first dimension, such that all gridded files have three dimensions (realization, x, y).

2 - /llc4320
All files under this directory tree correspond to gridded outputs of WW3 forced by currents from the MITgcm llc4320 in the California Current region. The available gridded variables are the same as described above (1). The files are named as follows:

llc_T{wave period}_{yyyymm}_{WW3 variable}.nc

such that the ensemble of mean wave directions for experiments with an initial wave period of 10.3 s, for snapshots of surface current from November 2011 will be in the file llc_T10.3_201111_dir.nc

3 - /model_stats
All files under this directory tree are derived from the files in the synthetic and llc4320 directories and can be generated locally using the Python scripts in the code repository. These files are included here just for completeness. The files S0.005_gridded_stats.nc, S0.01_gridded_stats.nc, and llc_gridded_stats.nc contain statistical parameters computed over the entire ensemble and were used to produce Figure 12 in Villas Bôas et al. (2020). The pickle files in the subdirectory inverse have the seasonal correlations plotted in Figure S2 of the supplemental material of Villas Bôas et al. (2020).

To reproduce all figures from Villas Boas et al. (2020), you should first download the source code from the repository https://github.com/biavillasboas/IdealizedWaveCurrent. The directories from this data collection (synthetic, llc4320, and model_stats) should then be downloaded and moved to a directory called data in the root directory of the project, like so:

IdealizedWaveCurrent
├── data
│ ├── llc4320
│ ├── model_stats
│ └── synthetic
├── figs
├── src
└── tools

with the directory tree above, one should be able to run all Python scripts in src and tools and completely reproduce the analyses from Villas Boas et al. (2020).
