Brazil Wave Climate from a High-Resolution Wave Hindcast
ABSTRACT: A detailed climatology of ocean wind waves in the South Atlantic Ocean, based on ERA-5 reanalysis and in a higher-resolution wave hindcast (ERA-5H), both developed by the European Centre for Medium-Range weather Forecasts, is presented. The higher resolution of the wave fields in the ERA-5...

The analysis of the decadal trends of wind sea and swell heights during the ERA-5H period (1979-2020) shows that the long-term trends of the total significant wave height in the South Atlantic Ocean are mostly due to swell events and the wave propagation effect from Southern Ocean storms.
