Special Issue Information

Dear Colleagues,

The Special Issue is the second volume of the series of publications dedicated to “Aircraft Interaction with Lightning and Thunderclouds” (https://www.mdpi.com/journal/atmosphere/special_issues/aircraft_lighting_thunderclouds). We pursue an understanding of the interaction between flying electrically floating objects with electrostatic electric fields, such as those generated by thunderclouds. The Special Issue is therefore focused on collecting experimental and theoretical knowledge about the following phenomena:

  1. Lightning strikes on airplanes, helicopters, drones, UAVs, etc.
  2. Lightning damage tests on novel materials used in space and aviation.
  3. Aircraft interactions with thundercloud electric fields.
  4. High-energy radiation from lightning and thunderclouds and potential hazard to avionic equipment and passengers.
  5. Laboratory studies on long sparks and charged aerosol clouds.
  6. Simulations and theoretical work on atmospheric electric discharges in general.

Humanity is set to double its current airplane fleet by 2040. Most of the new airplanes will be introduced in the areas associated with severe thunderclouds, i.e., Asia and Africa. The pressure imposed on the aviation industry by climate regulations will inevitably force us to reconsider the way we build and operate new airplanes. Deeper knowledge of the operation environment is therefore required to meet future challenges and maintain the incredible level of safety and trust that air transportation has achieved so far.

In this second volume of this Special Issue of Atmosphere, we invite scientists and researchers from R&D departments to join our effort to accumulate knowledge on aircraft interactions with lightning and thunderclouds. In-flight experimental campaigns, laboratory research, and modelling efforts are highly appreciated and welcomed.

The first results of the physical modeling of positive multistrike lightning formation processes using positively charged artificial thunderstorm cells are presented. Experimental studies have shown a significant influence of the number of thunderstorm cells and groups of model hydrometeors introduced into them on the probability of the initiation of repeated strikes. It was found that with an increased number of cells and groups of model hydrometeors, the probability of the formation of repeated positive discharges increases several times. When the second group of model hydrometeors has been introduced into the artificial thunderstorm cell, or when the number of cells has been increased, the probability of the repeated discharge initiation has increased almost in three and in four times respectively. It has been revealed that, depending on the arrangement of model hydrometeor groups in artificial thundercloud cells, the formation of repeated positive discharges from them may proceed both with the “connection” of the uncharged areas of the lower cell and with the “connection” of the upper cell. The parameters of the first and repeated impulse current pulses between the positively charged cells and the ground were determined. It was found that with an increasing number of model hydrometeor groups, the value of the charge neutralized during the stages of first and repeated discharge formation increases. When forming multistrike positive discharges with the “connection” of the upper artificial thunderstorm cell, 20–30% more cloud charge has been neutralized during the repeated discharge than during the formation of a single positive discharge. It was found that the formation of positive repeated discharges was observed in about half of the cases, and that the radiation power and impulse current amplitude at repeated discharges are higher than at the first discharge. This article discusses some possible reasons for such a ratio between the parameters of the first and repeated discharges. It is assumed that the discovered significant influence of large model hydrometeor groups on the probability of the formation and the characteristics of repeated positive discharges from artificial thunderstorm cells indicate a possible key influence of hail arrays in the thundercloud on the formation of repeated strikes of positive lightning and bipolar lightning. The obtained results show that artificial thunderstorm cells of positive polarity, together with groups of large model hydrometeors, have prospects for physical modeling and the investigation of processes of the formation of positive and bipolar repeated lightning strikes.
