本文利用辽东湾海域及其沿岸台站多年的海冰观测资料和有关气象资料,对该海域的海冰条件以及相应的气候规律进行了概率分析、研究了辽东湾南北两个分区的划分、冰厚与气温的关系、冰厚的极值概率分布、太阳黑子数以及El Nino现象对渤海冰情的影响及其长期变化的规律,得到一些可供辽东湾抗冰平台设计参考的数据和结论。 Based on the sea ice observation data and relevant meteorological data of Liaodong Bay sea area and its coastal stations for many years, this paper analyzes the sea ice conditions and corresponding climate laws in this area, and studies the division of the two subregions in north and south of Liaodong Bay. The relation between thickness and temperature, the extreme probability distribution of ice thickness, the sunspot number and the influence of El Nino phenomenon on the ice conditions in Bohai Sea and its long-term variation are analyzed. Some data and conclusions are obtained for design reference of anti-ice platform in Liaodong Bay.
