本文利用渤海及黄海北部冬季气温资料进行了谐波分析,研究了海冰与冬季冷暖的长期振动。结果表明,渤海及辽东湾有7,7年和23年振动周期,黄海北部有3.8年和23年周期,青岛则有 6.3年和 12.5年的振动周期。并探讨、分析了极移振幅与冬季气温的相关关系,该分析为渤海海冰的长期预报提供了依据。 In this paper, the use of the Bohai Sea and northern Yellow Sea temperature data for the winter harmonic analysis of the sea ice and winter warm and long-term vibration. The results show that the Bohai Sea and Liaodong Bay have 7, 7 and 23 year vibration cycles, the northern Yellow Sea has 3.8 years and 23 years, and Qingdao has 6.3 and 12.5 years of vibration cycles. The relationship between the amplitude of polar motion and the temperature in winter is analyzed. The analysis provides the basis for the long-term prediction of sea ice in the Bohai Sea.
