UTC Exoplanets and the Intermediate General Circulation Model Steven Vogt talks about a scientist who modeled the atmospheric circulation of a tidally locked exoplanet like Gliese 581 g in its habitable zone I m not sure which paper Vogt is referring to here Would you be able to add a discussion about this to the Gliese 581 g article No hurry on this It s in the video if you get a chance to watch it Event begins sometime around 29 27 They have really irritating video can t they just put it on youtube Interesting how I asked you this question right as it became an issue An editor just added that the tidally locked sides would be blazing hot in the light side to freezing cold in the dark side however I removed this because Vogt seems to refer to the climate models several times that contradict this statement And now I ve restored it after finding the source I ve evaded the issue for the moment but put a comment about something else on the talk page Thanks Meanwhile if you look at the PR puff notice in the pic the sun is orange red as presumably it should be but mysteriously the light reflected off the clouds has become white I finally found the guy and his work His name is James Kasting Have you heard of him Nope But I have found and now read Joshi et al 1997 which looks to be the main source for the atmospheres stuff Its quite interesting I ll summarise it here prior to dumping it somewhere put it in Interesting But isn t deposition of CO2 exothermic and thus would release heat into the atmosphere on the cold side so it would get warmer Nevermind obviously the GHE would be reduced by the loss and that would overwhelm the small amount of heat gained from deposition Yes the heat released is small and is soon lost Its vaguely similar to the way that waste heat from fossil fuel combustion is far less important than the CO2 released Gurk I ve just noticed that Vogt et al say M stars emit a large amount of their radiation in the infrared As a result since the greenhouse effect works by absorbing infrared radiation the surface temperatures would be higher than predicted by such simple calculations This is very badly broken Oops In memoriam Another valuable editor gone while the trolls remain And another I never knew him though for a year A victim of the jackboots Now gone forever alas 14 00 24 March 2011
