arctic oscillation

基本解释

In the higher latitudes, these patterns may be connected to the Arctic Oscillation.
在高纬度地区，这种气候模式可能与北极涛动有关。
This past winter’s negative phase of the Arctic Oscillation transported old ice (four, five, and more years old) from an area north of the Canadian Archipelago.
去年冬天北极这种负向振荡从加拿大群岛北部地区运来多年老海冰（四，五年或更多年的老海冰）。
An analysis of the relationships between the North Atlantic Oscillation(NAO), Arctic Oscillation(AO) and river runoff throughout Xinjiang region of China was presented.
分析了冬季北大西洋涛动（NAO）和北极涛动（AO）与新疆天山南北不同流域河川径流变化的关系。

In particular, in polar regions it appears to weaken the Arctic Oscillation winds.
FORBES: 2011 Forecast: World Outperforms U.S., Europe Scuttles
This pole-centred roundel of warm-in-cold is symptomatic of what climatologists call the negative phase of the Arctic oscillation (AO).
ECONOMIST: Britain’s cold snap is explained by the Arctic oscillation
When the Arctic Oscillation turns negative, that is, when the winds weaken, the cold air normally trapped around the North Pole surges south.

北极涛动
In this paper, the spatial-temporal structure of Arctic Oscillation is analyzed; the effect of the mid-high latitude atmospheric circulation anomaly to the summer rainfall of eastern China is discussed.
利用NCEP/NCAR再分析资料和台站观测资料分析了北极涛动的时空结构,研究了中纬度海气耦合的若干特征,并就中高纬度大气环流异常对中国东部夏季降水的影响进行了讨论。
