本文将南极海冰分为4个区:SPI1(0°-120°E),东南极海冰;SPI2(120°E-120°W),以罗斯海为主体的海冰区;SPI3(120°W-0°),以威德尔海为主体的海冰区;SPI4,全南极海冰区。北极海冰区分为3个区:NPI1(90°E-180°-90°W),太平洋侧冰区;NPI2(90°W-0°-90°E),大西洋侧冰区;NPI3,全北极冰区。本文使用了WDC-A的SIGRID海冰资料,以分析南极和北极各冰区之间的相互关系。发现两极各冰区之间存在着非常复杂的相互作用。其中最突出的特征是:两极海冰之间相互作用的振源是NPI2。SPI3是影响南极海冰的正反馈中心。SPI2则是南北两极海冰的负反馈中心。NPI2,SPI3和SPI2之间的相互作用最强,形成涛动关系。这种涛动关系不是同时期的,而是有较长的滞后时间差。两极海冰形成周期变化,其周期为5-6年,正与NPI2和SPI3自身变化周期一致。另外还有更长的循环周期9-11年
In this paper, the Antarctic sea ice is divided into four regions: SPI1 (0 ° -120 ° E), southeast Antarctic sea ice; SPI2 (120 ° E-120 ° W), the sea ice region dominated by the Ross Sea; SPI3 ° W-0 °), a sea ice zone dominated by Weddell Sea, and SPI4, a full Antarctic sea ice zone. The Arctic sea ice is divided into three zones: NPI1 (90 ° E-180 ° -90 ° W), the Pacific side of the ice zone, NPI2 (90 ° W-0 ° -90 ° E), the Atlantic side ice zone, and NPI3 Arctic ice region. This article uses the WDC-A SIGRID sea ice data to analyze the interrelationships between Antarctic and Arctic ice regions. It was found that there was a very complex interaction between the two polar ice regions. The most prominent feature is that the source of the interaction between polar ice is NPI2. SPI3 is a positive feedback center affecting Antarctic sea ice. SPI2 is the negative feedback center of the North and South Poles sea ice. NPI2, SPI3 and SPI2 the strongest interaction between the formation of Oscillation. This kind of oscillatory relationship is not contemporaneous, but has a long lag time lag. The period of polar sea ice formation varies from 5-6 years, which is consistent with the period of self-change of NPI2 and SPI3. In addition there is a longer cycle of 9-11 years
