Imagine how curious it would be if beyond Earth's poles, clouds existed only at the latitude that crosses New Zealand, Argentina and Chile. |
Such rising air would cut off air from the south polar region from mixing with the rest of the moon's atmosphere, causing smog to build up and form a cap over the pole. |
Titan's weather is very different from Earth's. |
We believe that it's no coincidence that Titan's south polar cap of smog extends from the pole to 40 degrees south latitude -- exactly where the methane cloud band appears. |
What's causing the bunching is unclear, and likely involves unknown features on Titan's still largely unexplored surface. |
