The trend of sea ice design thickness for the Bohai Sea and Northern Huanghai Sea
In recent years,clean energy such as wind power,photovoltaic and nuclear power has been widely devel-oped in the coastal waters of the Bohai Sea and the northern Yellow Sea.This paper focuses on investigating the sea-ice thickness of return period.Ice grades of time series for past 72 years significantly declines for the researched regions.Based on the multi-source observation data and refined numerical forecast data of sea ice in the past 20 years,this paper analyzes the ice conditions for this area.The results show that the ice grades present a downward trend for past more than 20 years.Under the influence of this general trend,the ice thicknesses decrease for differ-ent return periods comparing with the thicknesses from the sea ice zones.The design ice thickness of different sites is greatly affected by the local marine environmental conditions.In order to satisfy the needs of ocean engineering,it is necessary to assess sea ice parameters by updating the time series of yearly maximum thickness.
