How often does it Rain on Titan?

[james_davis_nicoll]

Introduction: We are privileged to live on one of only two worlds in the solar system on which liquids rain onto a solid surface : Titan is the other. Here we show that simple energy balance, numerical models of global and mesoscale circulation, ground- and space-based observations of clouds, and Cassini observations of surface change, are all consistent with Titan rains lasting 2-100 hours occurring at ~100-1000 year inter-vals globally, but 10-100 hours each Titan year (30 Earth years) at the poles. Implications for observations by Cassini and possible future missions are discussed.

So while it rains, even the wet places don't get rain much more often than most Earth deserts?
