中文摘要：
在秋天北极海冰集中(SICs ) 和北美的冬季降水之间的协会用单个价值分解被检验。结果显示出那一在北极的多数原文如此减少了被干燥条件，并且由湿条件在加拿大的多数上在大平原，南部的美国，墨西哥，东方阿拉斯加，和东南的格林兰上伴随，东北美国，并且格林兰的多数。与 SIC 可变性联系的大气的发行量异例显示出从秋天是坚持的到冬季并且为在秋天北极 SICs 和北美的冬季降水之间的 covariability 负责的波浪火车结构。这种关系为北美的冬季降水建议潜在的长期的眼界。
英文摘要：
Associations between the autumn Arctic sea ice concentrations （SICs） and North American winter precipitation were examined using singular value decomposition. The results show that a reduced SIC in the majority of the Arctic is accompanied by dry conditions over the Great Plains, the southern United States, Mexico, eastern Alaska, and southeastern Greenland, and by wet conditions over the majority of Canada, the northeastern United States, and the majority of Greenland. Atmospheric circulation anomalies associated with the SIC variability show a wave train structure that is persistent from autumn to winter and is responsible for the covariability between the autumn Arctic SICs and North American winter precipitation. This relationship suggests a potential long-term outlook for the North American winter precipitation.
