Titan's Tropical Weather

Hugh Pickens writes "Climate researchers Ray Pierrehumbert and Jonathan Mitchell at the University of Chicago say that Titan, the only moon in the solar system large enough to support an atmosphere, has many of the same weather features as Earth, but with completely different substances that work at temperatures that plunge down to minus 170 degrees Celsius. Pierrehumbert and Mitchell call Titan's climate 'tropical,' a climate that is warm to hot and wet year-round, because on Titan methane assumes the role of water and exists in enough abundance to condense into rain and form puddles on the surface. Titan's tropical nature means that scientists can observe the behavior of its clouds using theories they've developed to understand Earth's tropics. For example, Titan's atmosphere produces an updraft where surface winds converge to lift evaporated methane up to cooler temperatures and lower pressures, where much of it condenses and forms clouds, 'a well-known feature on Earth called an ITCZ, the inter-tropical convergence zone,' Mitchell says."

  1. Does Titan Really Exist? by Anonymous Coward · · Score: 1, Funny

    I think we should be wary of these so-called "scientists" who do nothing but tell us lies about so-called global warming, denying the truth. They are usually atheists, which explains why they believe in the absurd theory of heliocentricism. Instead of curing us with prayer, doctors kill our precious children by refusing to prescribe antibiotics. Furthermore, scietists are notorious for using shoddy un-Christian European software like Linux, thereby destroying our Great Nation's wealth maximization potential. Truly, is there anything less scientific than science?

    It is against this backdrop, friends, that I must share the modest proposal about my fears: What if Titan is just a myth created from the discredited theory of astronomy?
