Cluster formation in Hessdalen lights

In this paper we show a mechanism of light ball cluster formation in Hessdalen lights (HL) by the nonlinear interaction of ion-acoustic and dusty-acoustic waves with low frequency geoelectromagnetic waves in dusty plasmas. Our theoretical model shows that the velocity of ejected light balls by HL cl...

Description
Summary:In this paper we show a mechanism of light ball cluster formation in Hessdalen lights (HL) by the nonlinear interaction of ion-acoustic and dusty-acoustic waves with low frequency geoelectromagnetic waves in dusty plasmas. Our theoretical model shows that the velocity of ejected light balls by HL cluster is of about 104ms−1 in a good agreement with the observed velocity of some ejected light balls, which is estimated as 2×104ms−1. ► We present a new mechanism involving the charge production during rock fractures. ► Electric charges from rocks produce dusty plasmas in the atmosphere. ► Dusty plasmas can interact with electromagnetic waves in the atmosphere.
