Polar vortices occur when an area of low pressure sits at
the rotation pole of a planet.

Other recent research has also tied the loss
of polar ice to subtle changes in the Earth's
rotation, suggesting that these losses can slow the
planet's spin, in addition to shifting the location
of the
pole itself.
It is flattened at the
poles due to a very fast
rotation of less than 11 hours per Saturn «day,» but the
planet takes 29.5 Earth years to complete an orbit around the Sun.
The
planets may have a spin - orbit coupling effect on the Sun which affects its
rotation rate, which would then affect the solar dynamo and sunspot production, and therefore the build up
of magnetic flux at the
poles, and the length
of a solar cycle: if the solar cycle is weaker with less sunspots, it'll take longer for the build up
of opposing flux to reach the point when it flips the
poles.
«The high
rotation of the
planet — about 10 hours for a complete turn around its axis — and the heat coming from the lower levels
of the atmosphere certainly have a great impact to the formation
of the cyclonic pattern we have observed over the Jupiter's
poles,» he told Digital Trends.
