We also discuss the effect of horizontal resolution of meteorological forcing on maximum surge heights. This is carried out by upscaling the meteorological forcing from 0.225° to coarser resolutions up to 1.0°. For all TCs, TC intensity is decreased in coarser resolution datasets, resulting in lower maximum surge heights. In addition, reductions are larger for larger maximum surge heights. Moreover, results suggest that coastal slope and coastline complexity may affect surge heights at coarser resolutions more than TC size. For relatively simple coastlines (fractal dimension < 1.10), the reduction in maximum surge height is 0.02 – 0.17 m (10-34%) when using 1.0° resolution forcing compared to 0.225° resolution forcing. For more complex coastlines, reductions exceed 0.5 m, up to 1.24 m for Irma. This suggests that particularly along complex coastlines, high resolution meteorological forcing results in the more adequately modeling of storm surges.
