This is because that frequency shift can also be found in the wind vortex over the arctic ocean , u - wind in beaufort sea , v - wind in east siberian sea and the pdo index 因此，除热力因素外，动力因素引起的海冰的平流与该变频现象也存在一定的联系。
The anomaly of greenland sea - ice area can affect sand - storm ' s occurrence times in ningxia ( north of china ) in later through affecting air circulation backgrounds 格陵兰海冰面积的异常变化通过影响后期的大气环流，从而影响于夏(我国北方)沙尘暴的发生。

At the same time , sea - ice anomaly of hudson bay in may produced anomaly of geopotential height over greenland in spring , and height anomaly would continued to summer 同时哈得孙湾5月海冰的多少会造成格陵兰及其周围地区的高度场异常，这种异常从春季持续到夏季。
The change range of sea - ice extent during the periods of february - april and august - october is small , while that during the periods of april - july and october - january is large 其中2 - 4月以及8 - 10月海冰面积变化幅度不大，而4 - 8月和10月-次年1月海冰面积变化幅度则相当大。
