From cold to warm gas giants: A three-dimensional atmospheric general circulation modeling

摘要: Abstract We present a three-dimensional general circulation model suitable for simulating the atmospheric dynamics of giant gas planets. It was applied to studying changes induced by an increased heating due stellar radiation absorption compared Saturn-like planet. Such gravitationally unlocked “warm” extrasolar planets exist in large quantities at distances intermediate between those cold and hot transiting giants, instance, HD 155358b 96063b. Our simulations indicate that inclusion moderate meridional temperature gradient troposphere significantly alter stratosphere, especially zonal wind, which becomes superrotating on entire Thermal tides, are almost certain strong-lit fast-rotating planets, mostly circulation, and, given its weakness, may reverse it. The analysis show many these momentum deposited vertically propagating smaller-scale eddies trapped troposphere.
