The mechanism underlying lightning discharge is highly sought after and this research may offer previously unknown insights.
In the paper "Application of Genetic Algorithm to Estimation of Function Parameters in Lightning Currents Approximations," the genetic algorithm is applied for the estimation of the parameters of two-peaked analytically extended function (2P-AEF) which are used for approximation of measured and typical lightning discharge currents.
After this, the thundercloud electric field is approximately constant for several minutes until a lightning discharge occurs.
Based on the analysis results, the author estimated the potential of ball lightning discharge at 300-400 kV.
Sizes of cloud ice represent the meteorological condition, aerosol effect, atmospheric dynamics, and are closely related to the cloud electrification and lightning discharge. It is still not clear whether small or large ice sizes increase the lightning flashes.
The aircraft can therefore be a part of the natural lightning discharge process.

Today the researchers' mapping array consists of a collection of plastic tubs and other containers, each holding a solar-powered detector to measure radio-frequency radiation arriving from sparks within a lightning discharge. With multiple stations, the scientists can build a three-dimensional picture of how lightning appears and branches across the sky.
The lightning discharge path and what gets struck is determined by the first upward streamer that connects with the downward leader (Figure 1).
