Abstract
The data of the Cross-Calibrated Multi-Platform (CCMP) wind field was used as the background wind field to reconstruct the Yellow Sea and Bohai Sea wind fields for 30 years from 1991 to 2020. The observed and reconstructed wind fields were in good alignment. Reconstructed wind-field data were used to drive the SWAN model. In comparison, the calculated significant wave heights and measured data were in good agreement. Based on the SWAN calculation results, the wave elements of the 10-year return period were calculated to provide the input boundary conditions for the MIKE21 SW model. By calculating the wave fields near the fishing ports, the hidden dangers of marine disasters in six fishing ports in Qinhuangdao were analyzed. The results show that there are hidden dangers of marine disasters in the Xinkaikou fishing port; Daihekou, Yanghekou and Shanhaiguan fishing ports all have potential marine disasters risks. In addition, no hidden dangers of marine disasters in the Xieliangkou fishing port and Fishing vessel wharf port were identified.
