TLDR
In this paper, the authors review the recent results especially from the point of view of their effects on VLF/LF radio propagation in the earth-ionosphere wave guide.Abstract:
In recent years, at least two different ways in which energy from lightning discharges couples into the lower ionosphere and the radiation belts have come to the fore. In this paper, we briefly review these recent results especially from the point of view of their effects on VLF/LF radio propagation in the earth-ionosphere wave guide. We separately discuss two different mechanisms of coupling, namely lightning-induced electron precipitation, and lightning-induced heating and ionization of the lower ionosphere. We also discuss a planned active VLF wave-injection experiment designed to investigate ionospheric heating by VLF waves under controlled conditions and to generate ELF waves by modulated VLF heating.read more

Early VLF perturbations caused by lightning EMP‐driven dissociative attachment
TL;DR: In this article, the authors proposed a new mechanism for lightning-induced perturbations to VLF transmitter signals known as Early VlF events, which involves electron density changes due to electromagnetic pulses from successive in-cloud lightning discharges associated with cloud-to-ground discharges (CGs), which are likely the source of continuing current and much of the charge moment change in CGs.

On the occurrence and spatial extent of electron precipitation induced by oblique nonducted whistler waves

TL;DR: In this article, the onset delay and duration of precipitation steadily increase with increasing L-value, while the signal recovery time is independent of L-values for the LEP events associated with both storms.

On the numerical modelling of the VLF Trimpi effect
TL;DR: In this article, a theoretical and numerical approach for modeling the Trimpi effect in subionospheric VLF transmissions is presented, which is based on a multi-modal treatment of an assembly of point scatterers, and is subject to the Born weak scattering approximation.

Aspects of wave-particle interactions at mid-latitudes
TL;DR: The most significant source of particle precipitation into the ionosphere at mid-latitudes (L ∼ 2 − 3) is that which arises from the interaction between trapped particles and whistler-mode waves in the magnetosphere as discussed by the authors.

In-Flight Electromagnetic Compatibility of Airborne Vertical VLF Antennas
TL;DR: In this paper , two theoretical models were developed and compared with results from an experimental balloon flight directly through a storm front, based on the theoretical and experimental results, the most accurate model proposed was chosen, as well as a set of basic requirements for the balloon-borne VLF antenna system, reducing the risk of failure during operation in highly electrically active atmospheric environments.
