Outline
This study used ERA5 reanalysis data to collect an extreme wave event dataset for various regions in the Arctic Ocean during August to October from 1979 to 2021. The analysis focused on the frequency of extreme wave events, changes in extreme wave heights, features of wave power and wave direction distribution, as well as the change of sea ice during wave events. The results suggest that as sea ice decreases, the range of extreme wave activity in the Arctic expands. All regions, except the Barents Sea, exhibit an increase in the occurrence of extreme wave events. In particular, extreme wave heights in the East Siberian Sea and Laptev Sea have significantly increased at rates of approximately 3.5 cm/a and 2 cm/a, respectively, with event frequency reaching around 4 events per year. The dominant wave direction in the Laptev Sea is southerly, facilitating more frequent wave propagation into the ice zone compared to other seas, with an average wave energy flux ranging from 5−8 kW/m. The changes in sea ice within extreme wave events primarily occur in the marginal ice zones and are associated with wind direction: sea ice is more likely to decrease with on-ice winds, while it is more likely to increase with off-ice winds.
