红色精灵(red sprite)不同于发生在对流层中的雷电,它一般发生在雷暴云上方40~90km之间,通常认为是由强烈的雷电引起的.2007年夏季,在山东沾化首次观测到17次红色精灵,一次发生在7月28日,雷暴中心位于山东省冠县,与观测站的距离约为272km,另外16次红色精灵发生在8月1日深夜至8月2日凌晨,雷暴中心与观测站的距离约为315km.记录到的所有红色精灵均成簇(cluster)出现,而且,红色精灵呈现出多种形态,有柱状,带有天使状翅膀的柱状、胡萝卜状和跳舞状等.红色精灵持续的时间范围为40~160ms,几何平均值约为61ms.红色精灵与母体雷电的时间差范围在3.4~11.8ms之间,几何平均值为7.1ms.在红色精灵发生时段,正地闪在总地闪中所占的比例约是没有产生红色精灵时段所占比例的7倍.红色精灵并不常出现在对流发展较旺盛阶段,而是在雷暴系统开始减弱阶段频繁出现.
Unlike the lightning that occurs in the troposphere, the red sprite usually occurs between 40 and 90 km above the thunderstorm cloud and is generally thought to be caused by a violent lightning strike. For the first time in summer 2007, Secondary red elves, once occurred on July 28, the thunderstorm center is located in Guan County, Shandong Province, the distance between the observation station is about 272km, another 16 red elves occurred in the late August 1 to early August 2, the thunderstorm center The distance to the observatory is about 315 km. All the red elves recorded are clustered, and the red elves exhibit a variety of forms, including columnar, columnar, carrot-like, and dance-like with angel-shaped wings . The red elves last 40 to 160ms and the geometric mean about 61ms. The time difference between the red elves and the mains lightning ranged from 3.4 to 11.8ms with a geometric mean of 7.1ms. During the time when the red elves occurred, The proportion of blinks in total blinks is about seven times the proportion of the period in which no red elves were born.The red elves did not usually appear in the more vigorous stage of convective development but frequently occurred in the period when the thunderstorm system began to weaken.
