The term is used in political geography to explains a particualr area with definable characteristics and not always limted to governments and boundaries. A region often has a similarity in terms of governance,climate,terrain and language.
As Jupiter has the largest planetary atmosphere its lacks a clear boundary and gradually transitions to the liquid interior of the planet. Having their temperature gradient.
The jovian atmosphere has a large range of active phenomena including the band instabilities and anticyclones, and cyclones and storms and lightning.
These cyclones are large red, or brown such as the Great red spot of Jupiter. Hence, Jupiter has the most powerful type of storms being accompanied by the convection in the atmosphere as the striking of lightning from the clouds in 10 times more stronger than on earth.
Jupiter also consists of upper clouds, located in the low-pressure range are made of ammonia ice. Auroras are a permanent feature of the Jupiter's atmosphere based on the exiting models temperature predictions of the atmosphere are no higher than 400k.
Strong jets have been observed at the equator of the by the deep models. Temperature and winds are found to rise from the equator to the poles, thus confined within zones. As a comparison to the anticyclones, the jovian cyclones tend to be small dark and irregular.
