Applying the approach given in [7] to finding in the cloud the values of the electric potential [[phi].sub.r] for the radial distribution of the required potential [[phi].sub.r] in the simplified model of the thundercloud, we obtain:
Ms Irving continued: "This little girl's death was pronounced at 7.08am, on December 12, 2012, but it was never, was it, even after Alison Armour's report, treated as a murder inquiry?" "No," Mrs Thundercloud replied.
Assuming that the thundercloud capacitor's geometrical characteristics are fixed (i.e., A and d are constant), it can be argued that frequent lightning discharges limit the growth of the electric field E, which in turn limits the value of the potential [[phi].sub.N] and thereby reduces the values of Ip and hence [epsilon] as discussed above.
It should be stated that the wind considered in this study is mainly focused on the horizontal air flow and the updraft under a thunderstorm while the downdraft is not studied, because the area at ground level underneath a thundercloud with downdraft present is usually accompanied by precipitation while updraft is often without it [21].
The common type of lightning strike is the cloud-to-ground (CG) flash which occurs when the negative electric charges in the thundercloud emanate and travel to ground.
