The shape of the atmosphere on Earth is largely an oblate spheroid[w]; it is thinner at the poles and thicker at the equator.

As illustrated below, with the Earth's surface of the northern hemisphere conceptually flattened in a manner maintaining the distance between the surface of the Earth and the surface of the atmosphere, it reveals the atmosphere on a hemisphere is intrinsically a parabolic-shaped structure.

Note: The atmospheric layer of these simplified images were exaggerated to conceptually illustrate its parabolic-shaped structure.

[uvs]

Paradoxically, the apparent convex structure of an atmospheric layer in the hemisphere, is actually a concave structure in the conceptually flattened worldview; the Earth's atmosphere is fundamentally a spheroidal forced vortex formed largely with the Earth spinning on its rotational axis.

Fundamentally, such an intrinsic parabolic-shaped atmospheric structure is caused by the effect of a manifested atmospheric forced vortex[uvs] formed with the rotation of the Earth, which shaped the atmospheric structure in its apparent geometric form of an oblate spheroid.

On the atmospheric surface of a conceptually flattened Earth, the two geological poles at the highest latitudes in geometric vector[w] are at the two points with the lowest potential energy. And on the equatorial plane at zero latitude, the surface of the atmosphere is on the rim of its forced vortex with the highest potential energy.

This is a paradoxical effect caused cognitive paradox that is rendered in an obfuscated topsy-turvy[d] manner.

With this delusional observation meticulously elucidated, a crucial cognitive paradox is resolved and thus revealed the subliminally obfuscated forced vortex pair.

From the perspective viewing the North Pole[w] is at the top with the side view of the Earth, it can be visualized that the rotating Earth in its axial tilt is revolving around the Sun in the plane of the ecliptic[w].

Heuristically, the oblate-shaped structure of the Earth's nested atmosphere is as a result of the exerted centrifugal force[w] from the Earth that spins on its axis of rotation.

The observable tidal bulges on the Earth's nested atmosphere caused by lunisolar precession[w], is an ellipsoidal structure in superposition[m] with the main oblate-shaped atmospheric structure.

Fundamentally, the intrinsic ellipsoidal atmospheric structure is an elongated forced vortex pair formed by the tidal forces of the Sun and the Moon on the plane of the ecliptic.

From the UVS perspective, the rotational axis of the Earth is the main axis of the unisonal vortex mechanism[uvs] that render the angular momentum[w] to drive the tilted force vortex pair to cyclonically form it as a free vortex pair. And the axis perpendicular to the plane of the ecliptic, is approximately the secondary axis on which the tilted force vortex pair is in superposition as an intrinsic ellipsoidal atmospheric structure.

The precession effects render by the differential spin on these two axes in the nested atmosphere, cyclonically draws the atmospheric medium with a tilted angular momentum to spiral inwardly toward the core of the nested forced vortex pair on the Earth's axis of rotation, thus vortically transform it as a nested free vortex pair. The UVS research predicates a polar vortex is a nested atmospheric free vortex manifested on the polar axis with the precession effects of the Earth. All naturally occurred winds are modulated by the nested polar vortex pair in its precession effects.

The nested polar vortex pair formed on the upper atmospheric layers with its cascaded vortical columns manifested at the two geological poles, thus transformed the structure of these atmospherics layers as a nested form of torus-shaped structure.

The resolved cognitive paradox on the apparently convex atmospheric structure around a polar axis is intrinsically a concave structure in a hemisphere of the Earth, and the observable differential spin on two axes of the Earth that interacts with the manifested forced vortex pair on the rotational axis, constitute as the qualitative proof for the nested polar vortex pair is largely manifested with the precession effects of the Earth.

The grounding for its epistemic theories of truth: The underlying vortical structure and mechanism of polar vortex 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 paradoxes could be meticulously resolved, and all the related natural phenomena were then qualitatively analysed in the conceptual framework of UVS by inductive reasoning for explicating with their empirical evidence to predicate by abductive reasoning.

See the UVS topics on "The UVS' philosophy of science" and "Overviews of the UVS research" that elaborate on the methodology for the evaluations of natural phenomena.

The atmospheric effects of polar vortex

For the UVS perspective, the cold core phenomenon of polar vortex from mid to top section of stratosphere, is as a result of sunken mesosphere has filled the void in the vortex column. And the polar climate[w] is largely as a result of a polar vortex has vortically dispersed troposphere in the low pressure system of its nested vortex column, its effect causes the freezing air on higher altitude to be lowered nearer to the sea level in its vortex column. The UVS research predicates the polar climate is caused by the vortically dispersed atmospheric layers in the vortex column of a polar vortex that is filled with the cold air from a higher atmospheric layer. For the UVS perspective, the nested polar vortex of stratosphere and tropopause with its nested vortex column manifested within the boundary of the subtropical jet stream, is the causality for the subtropical climate[w]. The UVS research predicates the subtropical climate is primarily caused by the nested polar vortex with its nested vortex column manifested within the boundary of the subtropical jet stream.

The low-pressure polar vortex column at a polar region with its atmospheric layers vortically displaced, is the causality for the collision of cold front[w] and warm front[w] phenomena between the inner and outer boundary of its meandering polar jet stream[uvs], which marks the boundary of its polar vortex column. The vortically displaced and thinned out low-pressure atmospheric layers at a polar region, is the causality for the sudden drop of the temperature inside the polar vortex column.

From the UVS perspective, when the Solar System alignment[uvs] with its focused tidal force manifested on the atmosphere in a winter night at the northern hemisphere during the perihelion of Earth, the combined tidal forces of the aligned Sun and Moon would extremely decrease the altitude of the atmospheric layers at its polar focal point. As illustrated with the animation on right, during the first and third quarter Moon, the neap tide of ocean caused by lunisolar precession[w] would occur to form the largest tidal bulges as a result of tidal force[w]. The tidal depressions formed by neap tide in the nested atmosphere of Earth, stretches the nested atmospheric forced vortex[w]. With the much lowered altitude, the atmosphere is thus much shallower and less denser around the polar regions.

Sun The types of tides in a lunisolar precession cycle of Sun and Moon that affects Earth's ocean.

The UVS research predicates a polar vortex is significantly affected by the focused tidal force from an alignment of the major Solar System objects.

With a stronger torque-induced precession that occurs seasonally, when the cohesion force of air molecules in the nested atmospheric layers are overcome by centrifugal force in a spinning action, a vortex eye would open at the center of equilibrium. And a vortical chain reaction with self perpetual motion will then occur to form the vortex column until the formation of the cyclonic free vortex is peaked.

In summer, the tilted Earth with the pole positioned nearest to the Sun, the vortex column of its nested polar vortex would thus shrink toward the pole.

On a summer's day in southern hemisphere rendered by the axis tilt of a perihelion[w] Earth, at regions near the equator with the thickest atmospheric layers vortically pushed out by the rotation of the Earth, in high pressure systems with the atmospheric layers are denser and thicker at nearer the equator, could explain why those higher atmospheric pressure land regions are the warmest places on Earth when solar irradiance[w] and solar insolation[w] are increased with the axial tilt of the Earth.

In winter, the tilted Earth with the pole positioned farthermost away from the Sun, the vortex column of its nested polar vortex would thus open wider toward the equator.

With lesser dragging effect of landmass at the South Pole, the Antarctica polar vortex would thus be more intensified than the Arctic polar vortex for lowering and displacing the troposphere with more the freezing higher altitude air in its vortex column.

Therefore, on a winter solstice night rendered by the axis tilt of an aphelion[w] Earth, with the high altitude continent of the Antarctica polar vortex is also most intensified by the focused tidal forces of a perigee moon when the alignment of Sun-Moon-Earth is also aligned with the gas giants, and thus extremely intensify its nested polar vortex and jet streams, it would cause its lower pressure nested vortex column in the troposphere to become widely opened. With the reduced solar irradiance and solar insolation in a low pressure system of the nested polar vortex during winter, could explain why Antarctica[w] is the coldest place on Earth.

The seasonal variation on Earth, is rendered by the extent of how much the nested polar vortex has opened up toward the equator.

The UVS research predicates the seasonal variation on Earth is rendered by the extent of how much the nested polar vortex has opened up toward the equator.

From the UVS perspective, a polar vortex column of troposphere widened by precession effect, could cause polar climate to farther extend toward the equator. And the effect of a supermoon[w] in its lunar cycle during winter when a pole of Earth is tilted farthermost away from the Sun, would cause the polar climate to spread farthermost toward the equator.

See an externally linked report on "U.S. Midwest, Northeast hit by bitter cold temperatures" that reported on how a widened polar vortex of North Pole were causing cold climate further South.

These extreme climate variations on Earth are largely caused by the planetary mechanism that affects the nested polar vortex pair of the Earth.

See the UVS topics on "Little Ice Age" that elaborates on how the climatic minima on Earth could synchronize with some grand solar minima, "Polar jet streams" that elaborates on how a polar jet stream is vortically manifested by its nested polar vortex, and "The causality of subtropical desert" that elaborates on how a vortical mechanism could have ruled the subtropical deserts, and "Sunspots" that elucidates on how the extreme climates of Earth could be caused by a vortical mechanism governing the Sun in the Solar System.
