Revisiting the coastal sea level rise using altimetry and a high-resolution spectral wave model
Abstract
Coastal high-resolution simulations of wind waves considering ocean surface currents were performed with a 3rd generation spectral wave model to understand its effects on sea level rise.
The period of the study covers 2002-2018. The modeled results are compared with the Era5 significant wave height (Hs) and satellite altimetry data. The effect of coastal current is analyzed as a plausible explanation of the observed change in sea level trend close to the coast. Using the data sets mentioned above, we compute 2-D significant wave height (Hs) trends from 2002-2018 to conclude whether wave setup contributes to the coastal sea level trend. The correlation between Hs and sea level trends is analyzed to understand if it increases near the coast and if there is a direct relation between the changes in wave conditions and the sea level variations.- Publication:
