Atmospheric response to electric field pulse Original Research Article

The complete plasmochemical model was developed for the study of electric field perturbations impact on aeronomy of middle atmosphere and lower ionosphere. The model includes the following set of processes: dissociation, dissociative recombination and dissociative ionization, ionization, excitation, electron attachement and detachement, various ion-molecule reactions of positive and negative ions. It allows to calculate a lot of excited components and density variations of long-lived minor neutral components, which are especially important for the consideration of the sequence of perturbations. The simulation results on elves dynamics are presented. The comparison of calculated spectra and intensities with experiment is encouraging. The significant role of electron attachement processes at the heights of blue jet origin is shown. The scenario for the relationship between anomalous ground conductivity and blue jet (red sprite) is proposed.
