前言在我国的海区中,渤海和黄海北部由于其所处的地理位置和受气象条件影响,每年冬季都有结冰现象;因为冬季气候经常变化,所以各年的冰情互不相同。一般年份,渤海和黄海北部的冰情并不严重,对舰船航行和海上生产无甚影响。然而,对于那些冬季气候异常寒冷的年份,整个渤海几乎全被海冰复盖,黄海北部30米等深线以内的海区,也布满大量海冰。
Preface In the sea area of our country, the Bohai Sea and northern part of the Yellow Sea have icing phenomenon every winter because of their geographical location and weather conditions. As the winter climate changes frequently, the ice conditions of different years are different from each other. In general years, the ice conditions in the northern Bohai Sea and the Yellow Sea are not serious, and have little impact on navigating ships and offshore production. However, for those years in which the winter climate is unusually cold, the entire Bohai Sea is almost completely covered by sea ice and the sea area within the 30-meter isobath of the northern Yellow Sea is also covered with a large amount of sea ice.
