1·So scientists have started looking for the cause of the auroral variations.
因此，科学家们已经开始寻找极光变化的原因。
2·This high result was interpreted to reflect previous auroral activity.
这一高结果可以用以前的极光活动来解释。
3·Power law probability distributions of multiscale auroral dynamics from ground - based TV observations.
根据陆基TV观测多尺度极光动力学的幂律概率分布。
4·It is possible that the auroral oval shifts southerly and hence produces this effect in winter.
这可能是由于冬季极光卵向南偏移造成的。
5·With the increasing level of solar activities , it will likely trigger dazzling auroral displays at mid - latitudes 40 or above degrees north south from the equator.
由于太阳活动日趋频繁，在中纬度地区南北纬40度或以上地区也有可能出现绚丽多彩的极光现象。
