Based upon experimental observation in the laboratory, we propose that ionicwind from corona discharge inside a thundercloud would play an important rolein producing a rain gush. A cyclic chain of events inside a super-saturatedenvironment in a thundercloud is proposed, each event enhancing the successiveones until lightning occurs. These successive events are collision betweensnowflakes and rimers, charge separation, corona discharge, avalancheionization, ionic wind originating from the positively and negatively chargedmasses of cloud, vortex motion and turbulence when mixed with the updraft, morecollision, more charge separation, stronger corona discharge, and so on.Meanwhile, avalanche ionization would produce more CCN (cloud condensationnuclei) resulting in more precipitation and hence rimers formation in thesuper-saturated environment. More collision in the buoyant turbulence wouldlead to more fusion of droplets and the formation of larger rimers. The cyclicprocesses would repeat themselves until the electric field between the twooppositely charged masses of cloud was strong enough to induce a breakdown. Thelatter would create a sudden short circuit between the two charged masses ofcloud neutralizing the charges. There would be no more ionic wind, hence, muchless buoyant turbulence. The updraft alone would not be sufficiently strong tosupport larger rimers which would fall down 'suddenly' to the earth surface asa rain gush.

A new approach for rain gush formation associated with ionic wind
