The Cassini probe spotted a vortex over Titan’s south pole. It’s now early spring in Titan’s southern hemisphere. Cassini will be watching seasonal changes carefully for the next several years.
This is not unique to dense atmospheres in the solar system. Saturn has one. Venus, too.
It’s so interesting that this phenomenon occurs not only on Earth (hurricanes) but on much warmer and much colder bodies.
