Universal Vortical Singularity enlightenment on jet streams

Polar jet stream
From the perspective of UVS that is based on unisonal vortex mechanism, the two pairs of westerly jet streams roaming on surface of the troposphere of Earth are formed by polar vortices of higher altitude atmospheres from tropopause and stratosphere. These two pairs of westerly jet streams at both polar regions are known as polar jet streams and subtropical jet streams. Jet streams roaming around the polar regions are formed cyclonically at the boundaries of warm and cold air around a polar region are vortical singularities of vortex column and this infers they are caused by unisonal vortices. The boundaries of warm and cold air on surface of troposphere is caused by sunken stratosphere that has filled the void of vortex column.

See a UVS topic on "Vortices of Jupiter" that illustrates how jet streams are driven by their polar vortices to forms as cloud bands.

The phenomenon of polar jet stream is a vortrex driven by a high altitude polar vortex at a most pressurized bottom section that is smallest in diameter for vortex column with the highest wind speed, this section is sunken as furrow on the surface of a lower atmosphere that has bounced upward vortically. This is a momentum culmination of vortical dynamics in the viscous matter, in closed streamlines as a meandering torus shape structure the high speed jet stream has a lift that vortically flow in a loop perpetually. Solid blue lines and broken grey lines represent the streamlines. The red arrows show the direction and magnitude of the flow velocity. These arrows are tangential to the streamline. The group of streamlines enclose the green curves (C1 and C2) to form a streamtube. - Text and graphic for closed streamlines are excerpts from Wikipedia on streamlines. This is the force dynamics with an updraft and a horizontal momentum that are compressed within a boundary where commercial aircraft capitalizes to save fuel for trans-Atlantic and trans-Pacific flight, this is also how trans-oceanic hot air balloon and glider fly by finding the updraft in a jet stream. In the UVS worldview, the atmospheric layers have formed as vortexes on a polar axis, for the smaller inner loop at polar region that is conventionally known as polar jet stream, it is the vortrex of tropopause's polar vortex, while the larger loop at subtropical region that is conventionally known as subtropical jet stream, it is the vortrex of stratosphere's polar vortex. Polar vortex of Earth is a global scale clear air cyclonic storm that drives a meandering jet stream around it. The bottom section of unisonal vortex is where momentum culmination of vortical forces is at its peak, it is is where the discharging of vortex energy is at its maximum; the air pressure, angular momentum and wind speed are at their highest with radius at its smallest at the bottom of a vortex column, therefore radial force of the vortex is at its maximum here. This culminated voritcal force of a vortex is bounced on impacting an atmospheric surface and therefore is vortically pushed out and forms as a vortrex. It was recently known that tornado could be driven by a jet stream. See a UVS topic on "Tornado Alley" for further elucidation.

While the mechanisms of jet stream latitude shift are not fully understood with convention knowledge, UVS could qualitatively illustrates that the phenomenon of jet stream shift is caused by the circumstantial variations of its polar vortex column; jet stream and its polar vortex function as a unisonal system. See an external link on "A Shift Toward Aridity".

UVS qualitatively predicts that polar jet stream is the vortrex at a bottom section of polar vortex flowing in closed streamlines at high speed in a loop.
UVS qualitatively predicts that polar jet stream with significant differences in temperature at the boundaries of adjacent air masses is as a result of a higher atmosphere has sunk into the void of vortex column.

Subtropical jet stream
Conjecturably, subtropical jet stream is a phenomenon of energy discharging as vortrex at just below the surface of troposphere caused by a polar free vortex of the stratosphere. The main axis for this polar vortex of stratosphere is from Earth rotation and secondary axis is from revolving Earth that drives the polar vortex.

Equatorial jet stream
Equatorial jet stream is a phenomenon of energy discharging as vortrex at surface of troposphere caused by a tropical free vortex of the tropopause. The main axis of this unisonal vortex is from combined gravities of planetary alignments in a Solar System alignment effect acting on the atmosphere at the equator that form a primary forced vortex, the secondary axis is from Earth's rotation that drives these vortices. After a vortex eye is opened and the vortex formation is peaked on this very thin tropopause atmosphere, it could then draw another source of energy from gravity of Earth to sustain the free vortex, dissipates when the energy stored is discharged. Planetary gravitation of a significant planet, Sun or Moon could spawn a free vortex when the solar sytem object is directly above the sky or behind Earth. When a tropical free vortex of the tropopause is formed, the planetary gravitation pull becomes minority force acting on the depressed structure of the vortex; gravity of Earth could becomes a greater driving force after drawing energy from a thermal reservoir through a convection process. If a Solar System alignment has focused precession effects at night when Moon is also aligned with Sun, the equatorial jet stream would have the most intensity and highest wind speed.

Easterly jet stream Easterly jet stream is a phenomenon of energy discharging as vortrex at surface of troposphere caused by a satellite vortex of the tropopause polar vortex in Northern hemisphere. The vortex driving force is from a subtropical jet streams at the caved-in portion of the dual-core polar vortex of tropopause. This driving force causes the satellite vortex of tropopause to spin in a clockwise direction. After the vortex gathered enough strength, a vortex eye would open. Coupled by rotation of Earth, the air stream of the satellite vortex at the southern side could reach jet stream classification, which has to have a ground speed of more than 111 km/h. It could also be caused by satellite vortex of stratosphere. Satellite picture on right shows a meandering polar vortex occurred on various atmospheres on northern hemisphere with its satellite vortex. The meandering shape polar vortrexes are vortically formed by a tri-core polar vortex in tri-pole precession and affected by dragging effects on landmasses.
