报告了雷暴上空一种新记录的光学发射的初步观测结果。1994年6月至7月，Sprites94飞机战役期间，B/W和彩色摄像机首次记录下了“蓝色喷气机”，即从雷暴顶部向上传播的窄准直蓝光光束。射流似乎以大约100公里/秒的速度向上传播，并达到40-50公里的终端高度。在阿肯色州的一场风暴中，在22分钟的间隔内记录了56个例子。我们研究了一些可能的机制，但对这种现象没有令人满意的理论。
Initial observations of a newly documented type of optical emission above thunderstorms are reported. "Blue jets," or narrowly collimated beams of blue light that appear to propagate upwards from the tops of thunderstorms, were recorded on B/W and color video cameras for the first time during the Sprites94 aircraft campaign, June-July, 1994. The jets appear to propagate upward at speeds of about 100 km/s and reach terminal altitudes of 40-50 km. Fifty six examples were recorded during a 22 minute interval during a storm over Arkansas. We examine some possible mechanisms, but have no satisfactory theory of this phenomenon.
