Abstract—

It is ascertained that heating of volcanic material from the Etna volcano (Italy) by an apokampic discharge reduces the voltage at which a positive streamer (apokamp) starts from the discharge channel and increases its propagation speed. The luminescence spectra show these processes to be accompanied by the emission of easily ionizable K and Na, which is consistent with data on the elemental composition of Etna samples. A hypothesis is suggested about an increase in the appearance probability of blue jets and starters over sites of high volcanic activity at altitudes of 10–18 km (at the level of the troposphere).

火山物质对中低层边界附近瞬态现象形成影响的室内模拟

摘要—

可以确定的是，通过安培放电从埃特纳火山火山（意大利）加热火山物质降低了正流（安培）从放电通道开始的电压，并提高了其传播速度。发光光谱显示这些过程伴随着容易电离的K和Na的发射，这与Etna样品的元素组成数据一致。提出了一个假设，即在10-18 km的高度（对流层高度），在高火山活动位点上，蓝色喷射流和起动器的出现概率增加。
