The concept that electrodynamics of lightning is an electromagnetic vortex based on hypothesis of Universal Vortical Singularity is in a contemplating stage, although it is known that Earth's magnetic field does rotate with the Earth, this would directly affect the associated electromagnetic field. When an electric current passed through a conductor, a proportional magnetic flux is generated perpendicular to the axis of flow; this is a clue that electrical current travel vortical as an electromagnetic vortex. Also the main stroke of a lightning is thicker near the ground and thinner near the cloud also support the idea that structure of a lightning is an electromagnetic vortex, materials strike by lightning have corkscrew shape remnants in melts, and lightning often shown up in an inverted vortex structure. See Maxwell's Electromagnetic Theory on molecular vortex model of Faraday's "lines of force" in Maxwell's equations, a topic on Maxwell's molecular vortices and magnetohydrodynamics. Would the experts of electrodynamics please advise.

Electrons flows in electric current resembles viscous mass, as in plasma state, logically, vortical movement would be the best mode for conductivity as in easiest path with least resistance, vortically tunnels through vacuum. In atomic physics, the magnetic dipole moment of an electron is caused by its intrinsic property of spin within a magnetic field, as described in electron magnetic dipole moment. See a Universal Vortical Singularity topics on the geometrical structure of an atom.

This negatively charged cloud creates an attraction electrical force to the relatively positive charged Earth. The positive charge on an inversed parabolic surface of Earth is an inverted electromagnetic forced vortex, this is the main axis of an electromagnetic vortex mechanism. The relatively positively charged electromagnetic field of Earth attracted by the negatively charged cloud has created a reversed core vector for the inverted electromagnetic vortex.

Conjecturing based on the hypothesis, when conditions are met, stored electricity can be discharged through the easiest path from ground to cloud, with massive electrons accelerated in a vortical manner similar to energy transferred by tunneling through vacuum of vortex column, in the form of thin electromagnetic vortical columns latticed in an inverted vortex structure that has formed in a plasmatic ocean of intensified electromagnetic field.

It always appeared like lightning is striking down from cloud to ground, as show in these frame-by-frame images of lightning strikes, this is a complexly inversed illusion of a paradoxical effect, it is now scientifically known that most lightning strike from ground to cloud. Electrical current always discharge by flowing from positive pole to negative pole.

Conjecturably, the vortex column of a lightning stroke is narrower toward the cloud and wider from ground, this could be the reason for the light-up sequence of a lightning strike in a top-down manner where a dynamo effect that causes luminosity of plasma is stronger on vortex column with smaller diameter; the lightning therefore lit up from the top initially. This vortical reaction would have created a paradoxical illusion that makes it appeared like lightning strike down from cloud to ground.

Image on right illustrates the effects of oncoming solar wind with its stream of ionized particles directed on magnetosphere of Earth, and showing solar winds was repelled by it.

Lightning are known to peak in the afternoon, hypothetically, with solar wind directing towards Earth, the electromagnetic field of in a stream of charged particles from solar wind of Sun would interact by pushing to compress the magnetosphere of Earth, this would intensify the electromagnetic field around those clouds directly under the Sun, and therefore electrical conductivity would have increased that can aid the discharging of any built up electrical charges.

The jet stream of an atmospheric vortex is a catalyst for enormous scale self-perpetuating dynamo mechanism with consistence vortical activity that has dynamo effect on bipolar water molecules, in the process it stores huge electrical charges in cyclonically consolidated clouds.
