So summer has arrived in Titan’s northern hemisphere, but its weather is not changing quite as expected. For one thing, the moon has been nearly cloudless for years, when (according to computer simulations) the summer storms should have begun. That’s why the formation of a cloud bank over the methane lake Ligeia Mare is exciting, as I explained for The Daily Beast.
Cloud watching is important. Clouds carry material—water on Earth, methane on Titan—from one part of the atmosphere to another. They’re a way a world carries liquid from one region to another, in the form of evaporation and rain. A lake may dry up in one region, but a new one can form when rains fill a basin elsewhere. We know very well how that process works on Earth, but Titan’s weather is still mysterious in many ways.
But that’s one part of the mission of the Cassini probe orbiting Saturn. [read more…]
The Cassini team also put together a short video loop, showing the cloud bank forming, moving, and dissipating.
