I think there's a lot of subtle detail here that might be hidden from the eye.
I took the "summer clouds animation" (PIA21051: Watching Summer Clouds on Titan) and constructed a rough median frame by computing the pixelwise medians from the first, middle, and last frames. Then, I created a new animation which subtracts the median from each of the frames in the original work by Jason Perry. I think this makes subtle polar clouds (fog banks?) much more obvious: I count at least nine at one point. This also makes the rotation of the winds over a large area around the pole quite evident. In order to post here, I needed to shrink the animation 4x… I think the key details are still obvious. |
