Brazil Wave Climate from a High-Resolution Wave Hindcast

A detailed climatology of ocean wind waves in the South Atlantic Ocean, based on ERA-5 reanalysis and a higher-resolution wave hindcast (ERA-5H), both developed by European Centre for Medium-Range Weather Forecasts, is presented. The higher resolution fields ERA-5H (22 km) allowed better description sea swell features compared to previous global regional studies along Brazilian coast. Overall, it shown that are more prevalent carry energy offshore area study area, while dominate nearshore regions, especially northern coast Brazil. influence different climate indices significant heights patterns also presented, with two behavioral groups showing opposite correlations North Oscillation Southern Annular Mode than Index. analysis decadal trends during period (1979–2020) shows long-term total height Ocean mostly due events propagation effect from storms.
