| 摘 要： | 利用1961年12月—2022年2月新疆冬季气温、北极海冰等资料，探讨北极海冰变化影响新疆冬季气温的物理模态、影响机制。结果表明，北极海冰的变化与新疆大部冬季气温呈正相关，北极海冰变化通过改变北半球大气高低空配置进而影响新疆冬季气温。另外，不同海区的海冰变化对新疆冬季气温的影响有显著区别：格陵兰海—丹麦海峡、拉普捷夫海—东西伯利亚海海冰异常偏多时，新疆大部冬季气温偏高。巴伦支海—喀拉海、鄂霍次克海—白令海峡、哈德孙湾—戴维斯海峡海冰异常偏多时，新疆大部冬季气温偏低。

| Abstract: | Based on the datasets of the winter temperature in Xinjiang and Arctic sea ice from December 1961 to February 2022, the physical mode and mechanism of Arctic sea ice changes affecting Xinjiang winter temperature are discussed. The results show that the changes in Arctic sea ice are positively correlated with the winter temperature in most of Xinjiang.The changes in Arctic sea ice are able to affect the winter temperature in Xinjiang by changing the circulation configuration between upper and lower levels in the northern hemisphere. In addition, the impacts of sea ice changes in different sea areas on the winter temperature in Xinjiang are found to be significantly different.When the sea ice is above normal in Greenland Sea-Denmark Strait, Laptev Sea-East Siberia Sea, the most of Xinjiang would be warmer than usual. However, when the sea ice is above normal in the Barents Sea-Kara Sea, the Sea of Okhotsk-Bering Strait, Hudson Bay-Davis Strait, the winter temperature would be lower than usual in most of Xinjiang. |
