Synchronous Observation and Numerical Forecast Product Test of Ocean Waves in the Central Bohai Sea

Based on the observed ocean wave data of the synchronous observation experiment conducted at two stations in the central area of the Bohai Sea from June 20 to July 23, 2021, the statistical characteristics of waves in summer in this area are analyzed, and the numerical wave forecast products in the Bohai sea area are compared and verified through the observation data. The results show that the overall trend of the ocean wave elements at two observational stations is similar, the main wave direction is SE—SSE, and the cross-zero period is basically within 5 s, and the maximum significant wave height is approximately 2 m. The direction of the maximum wave height at both locations is from the SE. During the observational period, there are two obvious wave growth processes, and the significant wave heights at the two stations are different in these processes, which may be related to the wind fetch. The comparison of the numerical forecast products shows that the simulation result at the observation position is acceptable, the overall variation trend of wave characteristic parameters is consistent with the observation. The numerical forecast data can provide reference for offshore engineering operations.
