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)。

The result indicated that the assignment along with the balance aqueous phase acidity, the initial extractant concentration, and the duration of oscillation increases.

结果表明，分配比随振荡时间、萃取剂初始浓度的增加而增加，随着平衡水相酸度的减小而增加。

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

She said that this year's conditions were partly caused by a move to a negative phase of the North Atlantic Oscillation which would be likely to lead to more frequent cold, drier winters - like the 1960s - and also wetter summers for 10-20 years.
