Full description

The data is from a Regional Ocean Modeling System free-running, hydrodynamic simulation of the East Australian Current System. The model has a horizontal resolution of 2.5-6 km in the cross-shore direction and 5 km in the alongshore direction, and 30 vertical s-levels. The model domain covers the southeastern Australia oceanic region from 25.1-41.5°S and 147.1-162.2°E, and the grid is orientated 20 degrees clockwise to be predominantly orientated alongshore. The time period covered is 1 Jan 1994 to 30 Sept 2016. The model outputs provided are daily averages of the following variables: Two-dimensional variables: Sea surface height (zeta), barotropic cross-grid velocity (u) and barotropic along-grid velocity (v)Three-dimensional variables: Temperature (temp), salinity (salt), density (rho), cross-grid velocity (u), along-grid velocity (v) and vertical velocity (w), temperature time rate of change (temp_rate), temperature horizontal advection term (temp_hadv), temperature vertical advection term (temp_vadv), temperature horizontal diffusion term (temp_hdiff), temperature vertical diffusion term (temp_vdiff). In this version, the heat budget terms (temp_rate, temp_hadv, temp_vadv, temp_hdiff and temp_vdiff) are set to be zeros on the land.

Methodology

This model is described in Li, J., Kerry, C. and M. Roughan (2021) "Dynamics of interannual eddy kinetic energy modulations in a Western Boundary Current", submitted to Geophysical Research Letters. The model configuration is the same as the 22-year free-running simulation described in Kerry, C. and M. Roughan (2020) "Downstream Evolution of the East Australian Current System: Mean Flow, Seasonal, and Intra-annual Variability". Journal of Geophysical Research: Oceans, 125(5). doi: 10.1029/2019JC015227. Different from that in Kerry, C. and M. Roughan (2020), this model is forced with the hourly 12-km Bureau of Meteorology Atmospheric high-resolution Regional Reanalysis for Australia (BARRA-R) and include the TPXO8 tide forcing. The model output in this dataset is an upgraded version of Kerry, C. G. and M.
