Polar Cyclone

(storm centered on the pole)

The term Polar Cyclone refers to a storm in the vicinity of a pole of a planet, in particular, one centered on the pole. Planets are likely to have a permanent Polar Vortex, the pole-ward part of a typical planetary circulation pattern such as that including Hadley Cells.

Jupiter and Saturn hove storms at the poles, and in the case of Jupiter, a number of long-lived storms in the region. Given the poor view of their poles from Earth, the planetary space missions have been very informative.
