文摘

We analyzed Saturn’s North Pole and South Pole as seen by Cassini Orbiter. Our multispectral analysis reveal the cloud morphology of both of Saturn’s polar vortices. Our analysis reveals detailed structure of the North Polar wind field. We reveal the presence a bright cloud feature that appears in short wavelengths over the south pole in 2007. We predict the formation of a bright feature over the north pole before the next equinox.
