The active surges mostly appear around midnight, while the transpolar arcs mainly occur after midnight. 向日极光弧则主要出现在子夜前后，子夜前比子夜后多，极向和天顶比赤道侧多。
Established 5 December 1944.Also known as the "Defense of the Soviet Transpolar Region" and "Defense of Polar Region" medal. 1944年12月5日确定了这种奖章，做为防御跨北极及北极地区的一种奖章。
The two transpolar shortwave time signal circuits,Moscow and Irkutsk to the Great Wall Station in Antarctica, are used to study the fading characters for shortwave long circuit. 为了研究过极区的短波长电路的衰落特性，在南极长城站收测莫斯科、依尔库茨克的短波授时台信号，并给出各频率对应的衰落深度、衰落率、衰落平均持续时间等参数的统计特征和衰落幅度分布曲线。
The simulated general circulation in Canada Basin is strong anticyclonic ocean surface current, and there is a Transpolar Drift Stream (TDS). Their speeds are 2-5cm/s and stronger in winter than in summer. 北冰洋和北大西洋海冰的漂移速度和方向的特征主要有:在加拿大海盆区常年存在着明显的反气旋式的海冰环流型,并且有明显的穿极漂流,漂移的速度一般在2-5cm/s。
