The above images show aurorae are associated with various types of vortex in different shapes and sizes, see vortex definitions. These are evidence that aurora is caused by polar vortex of thermosphere. Solar wind would have contributed to the intensity of polar vortices pair and perturbed the polar aurorae, it is not the direct cause for polar aurora to glow vortically; vortical reactions of polar vortex is the underlying cause. Solar winds are streams of ionized hydrogen atoms while aurora on Earth is mainly the glow of ionized oxygen atoms.

UVS predicts that polar aurora is induced by polar vortex of thermosphere.
UVS predicts that the electromagnetic storm in the presence of an aurora is caused by the vortical effect of vortex.

Electromagnetic polar vortex on thermosphere can be triggered and affected by focused gravities of aligned planets in a solar system alignment effect. The planetary alignment of Jupiter and Saturn on an approximate 11 years period with Sun and Earth would synchronize the activities on polar vortex of Earth, and sunspot of Sun. Aligned Sun, Earth, Moon, Jupiter and Saturn Refer to the geometrical structure of magnetosphere that explains its torus structure, this is a primary cause that forms electromagnetic polar vortex. Solar wind repelled by magnetosphere of Earth Torus structure magnetosphere Electromagnetic polar vortex pairs Refer to The fundamental of unisonal vortex mechanism for detailed explanation on naturally occurred polar vortex. See a UVS topic on "Vortical patterns of planetary nebulae" that illustrates on glowing atmospheres that also works on the same principles, supposedly caused by the polar vortices of a diffused star. See also other UVS topics that elaborates on vortical phenomenon in "The geometrical structure of magnetosphere" and "Gas and dust tails of comet". Based on unisonal vortex mechanism, the phenomenon of Antarctica Ozone Hole is also triggered by a polar vortex.

 

These polar aurorae of Jupiter and Saturn were also caused by the dynamo effect of polar vortices. The plasma glows were from excited atomic hydrogen as a result of dynamo effect of polar vortices.

Disclaimers: The above revolutionary discoveries and conjectures based on an unheard-of hypothesis of Universal Vortical Singularity with radical ideas are unconventional, the explorations of the uncharted at fundamental stage might not be thoroughly covered, bound to have shortcomings, loose ends and errors, many details and assumptions have yet to be further researched, probed, evaluated, validated and proven. Many of the explanations forwarded are in informal manners for casual understanding of the topics presented, any term or statement if offensive in any manner or whatsoever is most regretted.
