Great Barrier Reef cyclonic wave climate using Geoscience Australia Synthetic Cyclone Tracks

Full description

Cyclonic wave climate information (significant wave height, wave energy flux, nearbed horizontal velocity amplitude, duration above 4 m significant wave height) at several return periods (10, 50 and 100 years). The wave climates used synthetic cyclone tracks for RCP 8.5 at 2010 and 2050, developed by Geoscience Australia. These tracks were applied using the Holland (2010) parametric gradient winds and Kepert (2001) boundary layer model to an extended version of Callaghan et al (2020) wave model of the Great Barrier Reef (GBR). The wave model extension introduced on-reef estimates. The wave model bathymetry applied is identical to that used in Roelfsema et al (2021), albeit resampled at 100 m increments. The extension to Callaghan et al (2020) model involved an additional 301 wave grids of various rotations. Information from these grids were used to estimate wave climate information on ten non-rotated grids across the GBR that are suitable for use in GIS systems (see image file with each case for visualization of grid locations).
