本文分析了北大西洋表层海温对冬季渤海海冰的影响,其影响时间为9个月左右。同时,指出了海温的韵律造成了北大西洋春季海温与冬季渤海海冰之间的关系,这个关系可做如下解释:北大西洋海温通过韵律活动在冬季出现与春季类似的热力特征。冬季的海温加热大气,从而影响冬季的大气环流。最后,通过不同地区之间的海气相互作用,海温的影响从北大西洋传到东亚。所以,应该认为是海温韵律造成了北大西洋春季海温与渤海冬季海冰之间的关系。
This paper analyzes the effect of the surface temperature of the North Atlantic on sea ice in the Bohai Sea in winter, and the impact time is about 9 months. At the same time, it was pointed out that the rhythm of SST caused the relationship between the spring SST in the North Atlantic and the sea-ice in the Bohai Sea in winter. This relationship can be explained as follows: The SST in the North Atlantic has similar thermal characteristics to the spring in winter through rhythmic activity. Winter sea temperature heats the atmosphere, thus affecting the winter’s atmospheric circulation. Finally, the effects of SST are transmitted from the North Atlantic to East Asia through the interaction of sea-air between different regions. Therefore, it should be considered that the rhythm of SST caused the relationship between the spring sea temperature in the North Atlantic and the winter sea ice in the Bohai Sea.
