Cross section of a two level atmospheric vortical system sketch diagram for illustrating the interactions of airflow with vortical push momentum.
See the UVS topic on "Atmospheric polar vortex" that illustrates the apparently convex structure of a nested atmosphere in a hemisphere, is actually a concave structure.
From the UVS perspective, the smaller inner atmospheric loop at a polar region formed on the surface of troposphere, as shown in the image at above left, known as the polar jet stream, is supposedly formed by the vortrex of the tropopause polar vortex around its outer vortex column.
And the larger loop at subtropical region, known as subtropical jet stream, is supposedly formed by the vortrex of the stratosphere polar vortex around its outer vortex column.
As can be empirically observed with its underlying structure and mechanism illustrated, a jet stream is manifested by its polar vortex. It is thus a qualitative proof that a jet stream is a sub-structure of its atmospheric polar vortex.
UVS predicates that jet stream is formed with a vortrex manifested at the bottom section of its atmospheric polar vortex to flow in closed streamlines of a ring torus structure.
The grounding for its epistemic theories of truth: The underlying structure and mechanism of a jet stream as explicated with its hypothetical construct based on the UVS model, elucidated its delusional observations that render its misconceptions, mysteries, and anomalies. Thus, its cognitive paradox was meticulously resolved, and all the related natural phenomena were then qualitatively analysed in the conceptual frameworks of UVS by inductive reasoning for explicating with their empirical evidence to predicate by abductive reasoning.
Based on the unisonal vortex mechanism, a polar jet stream is impelled by a high altitude polar vortex. And with the precession effect of a wobbling Earth, the momentum culmination of vortical dynamics in the medium of the nested atmosphere, manifests the polar jet stream as a meandering nested torus-shaped structure of air flow with closed streamlines.
The bottom section of unisonal vortex is where momentum culmination of vortical forces is at its peak, this is where the discharging of vortex energy is at its maximal. The air pressure, angular momentum and wind speed are at their highest with the radius of its vortex column is at its smallest at the bottom, vorticity is therefore is at its maximum there. This culminated vortical force of a vortex is bounced on impacting an atmospheric surface, and therefore air is vortically pushed out to form as a vortrex.
See the UVS topics on "The vortices of Jupiter" that illustrates how jet streams are driven by their polar vortices to form as cloud bands, "Tornado" that elaborates on how a tornado cluster can be impelled by a polar jet stream, "Ocean jet stream" that elaborates on how oceanic jet streams are caused by a nested oceanic free vortex, "Dust devil" that elaborates on the upward lifting mechanism of vortrex, and "The causality of subtropical deserts" that elaborate on how subtropical deserts were caused by the subtropical jet stream with the Hadley cells it impels.
From the UVS perspective, a jet stream and its polar vortex function as a unisonal vortical system. And its vortex eye can open wider to a lower latitude region when the polar vortex is intensified, or reduce in diameter and thus moves to a higher latitude region when the polar vortex is weakened. Perceivably, the phenomenon of jet stream shift, is caused by the intensity variations of its undulating polar vortex.
See an externally linked topic on "A Shift Toward Aridity" that reports on shifting of jet stream.
UVS predicates that the shifting of jet stream latitude is caused by the intensity variations of its undulating polar vortex.
If a Solar System alignment has focused precession effects at winter night when Moon is also aligned with Sun, with all else unchanged, the jet stream would have the highest wind speed with the vorticity of its nested polar vortex intensified.
See the UVS subtopic on "The T-junction crossed alignment of Solar System objects" that elaborates on the vortical effects caused by a peculiar arrangement of Solar System objects
From the UVS perspective, a subtropical jet stream is rendered by the vortical column of its polar vortex of the stratosphere that has had opened up to the subtropical region around the Earth.
For its comparative analysis with Jupiter's cloud bands, the subtropical jet stream pair is an invisible pair of Earth's cloud bands that has vortically formed by its pair of stratosphere polar vortices with their vortex columns opened to the subtropical latitudes on both hemispheres.
See the UVS topics on "The atmospheric effects of polar vortex" that elaborates on the tri-core hexagonal-shaped nested polar vortex with a manifested satellite polar vortex, "Retrograde cloud bands" that illustrates the underlying mechanism for the easterly jet streams on Juipter, "The hexagonal-like cloud structure of Saturn" that illustrates a similar tri-core polar vortex on Saturn, and "Bermuda Triangle" that elaborate on how a manifested satellite clear air polar vortex can cause mysterious circumstances.
Disclaimers: The treatise of Universal Vortical Singularity (UVS) in its epistemological paradigm shift, is fundamentally unconventional. Its hypotheses grounded on a generally unheard-of UVS model, bound to have shortcomings, such as loose ends, errors, and omissions errors. Many details and assumptions in its propositions have yet to be further researched, probed, evaluated, validated, or verified. Its implicit explanations are for casual understanding of the UVS topics presented in the UVS worldview, so if any term or statement is offensive in any manner from whatsoever perspectives, is most regretted. Links to other sites do not imply endorsement of their contents; apply appropriate discretion whenever necessary. Also, the content of the UVS topics, from time to time could be arbitrarily modified without any notice.
Viewing tips: Despite the presentations of the UVS web pages has went through much accommodation for their viewings on smart phones, they are still not entirely friendly to these mobile devices. For the best experiences, use a MS Windows based PC or computer system with Java enabled browser for running its interactive applets. (Such as Java Applet of Moiré pattern, JPL Small-Body Database Browser, and Planet Finder.)
