Short summary
Our results suggest that lightning strokes would probably influence the ionosphere and thus give rise to the occurrence of a sporadic sodium layer (NaS), with the overturning of the electric field playing an important role. Model simulation results show that the calculated first-order rate coefficient could explain the efficient recombination of Na+→Na in this NaS case study. A conjunction between the lower and upper atmospheres could be established by these inter-connected phenomena.
