Tuvalu Wave Hindcast

Date modified: 25 April 2023

The dataset is a 44-year hindcast (1979-2022) of the wave conditions in Tuvalu using the unstructured version of the third-generation wave model Simulating Waves Nearshore (UnSWAN).

The model domain covers the area between 174.5˚E and 181.5˚W and between 11.5˚S and 4.5˚S. The spatial resolution of the flexible mesh ranges from 20 km offshore, in deep water, to 300 m nearshore, in shallow water. The mesh was generated using OceanMesh2D, a MATLAB based software package for two-dimensional unstructured mesh generation (Roberts et al., 2019). The model was forced with 1-hourly spectral wave boundary conditions and 10 m winds from the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis v5 (ERA5). A detailed description of the model can be found in Wandres et al. (2023).
