本文应用1953—1977年50°N以北、160°E—110°W范围内的月平均北极海冰面积资料,北太平洋副热带高压面积指数和北太洋海温资料,统计分析了11—7月极冰与1—7月海温的时滞相关场和1—7月海温与滞后0—11个月的副热带高压的相关场。 计算表明,春季极冰号海温的时滞相关区几乎与加利福尼亚寒流和部分北赤道洋流区相重合,而加利福尼亚寒流区和部分北赤道洋流区正是海温与副高的主要时滞相关区。由此可以认为,在冰-海-气三者的相互作用中,北极海冰对副热带环流影响的可能途径之一,是通过大洋中的洋流输运影响海温来完成的。
In this paper, monthly average Arctic sea ice area data in the range of 50 ° N north and 160 ° E-110 ° W from 1953 to 1977, the North Pacific subtropical high area index and the North Pacific sea temperature data are used to analyze the data from January to July Related fields of polar ice and SST from January to July and related fields of January to July SST and lag 0-11 months of subtropical high. Computation shows that the time-lag correlation zone of the spring polar ice temperature almost coincides with the cold current of California and part of the northern equatorial current area, whereas the cold current area and part of the northern equatorial current area of California are the main time-lag related areas . From this, we can conclude that one of the possible ways for the Arctic sea ice to affect the subtropical circulation in the interaction of ice, sea and atmosphere is through ocean current transport in the ocean to affect the sea temperature.
