Even light thunderstorm can cause massive polar cyclones on Saturn
NASAâ€™s Cassini spacecraft seems to be giving us new insights into Saturn and its atmosphere. There is no denying the fact that we actually lack many necessary information about the far off Saturn and its violent polar cyclones.
The latest images and data that came thanks to NASAâ€™s Cassini spacecraft suggest that merely a slight thunderstorm is needed on Saturnâ€™s atmosphere to trigger powerful cyclones capable of sweeping its poles.
Reports from the top space agency suggest that NASA astronomers were actually able to introduce Cassiniâ€™s data into a computer model that helped them better understand the origin of the mysterious vortexes, a mystery that had remain unsolved for decades.
Astronomers associated with NASA are of the opinion that the new data can also help them remotely study large-scale atmospheric phenomena on exo-planets, as well. Cassiniâ€™s imagery revealed that Saturnâ€™s polar cyclones are linked to â€œhot spots,â€ while the north polar cyclone is surrounded by a mysterious hexagonal cloud that blankets the planetâ€™s north pole. NASA scientists believe that the bizarre feature was generated by violent eddies that envelop the central cyclone.
Morgan Oâ€™Neill is of the opinion that â€œBefore it was observed, we never considered the possibility of a cyclone on a pole,â€ Oâ€™Neill and team members were able to come up with a simple model of the remote planetâ€™s atmosphere, which had triggered a cohort of minor thunderstorms over the course of time. The model showed that those storms dragged atmospheric gases towards the poles where they created a spin in the atmosphere which resulted in the large polar cyclones we observe today.
