查询词典 aurora polaris

Multiple wavelengths characteristics of dayside aurora activities were investigated with these keograms and in reference to all-sky images. It was found that there are three repeatedly appearing aurora activity regions along the dayside aurora oval. They are, Region A around 0900MLT in which aurora moves poleward while its intensity decreasing, and its form changingfrom arc to corona with time; Region B around 1330MLT in which aurora moves equatorward while its intensity increasing, and its form changing from corona to arc in time; Region C around 1330MLT in which aurora expands poleward while its intensity decreasing, and its forma evolving from arc to multiple arcs in time. There is a narrow belt of aurora activity in North-South direction between Regions A and B, which is dominated by weak and red corona aurora.

初步分析发现，沿日侧极光卵不论磁静日还是磁扰日，在三个波段上都同时观测到了四个重复出现的极光活动区，即0900MLT附近的A区、1330MLT的B区和1630MLT的C区以及1200MLT附近的G区。A区内的极光活动由低纬向高纬运动，强度逐渐变弱，形态由较宽的弧状极光向冕状极光演变；B区内的极光活动由高纬向低纬方向运动，形态呈现为冕状极光向较窄的极光弧的演变，极光强度逐渐增强；C区极光活动向高纬方向展宽，强度逐渐变弱，极光由单弧向多重弧演化；而在A与B之间存在一个纬度范围相对较窄的极光活动区G区，该区的极光呈现暗弱的冕状极光。
