Investigating the thermal structure in Titan's atmosphere with a Net Exchange Rate formalism
Abstract
Latest improvements brought to the radiative transfer in the Titan's 3-dimensional Global Climate Model have significantly improved the modeled circulation in the middle atmosphere. The thermal profile now feature a stratopause and the vertical zonal wind profile is now closer to the observations. Here we analyze the up-to-date opacities with a Net Exchange Rate formalism to explore the energy exchanges that control the thermal structure. We particularly focus on the radiative effect of seasonal variations of trace compounds and investigate a possible radiative origin of the zonal wind minimum in the low stratosphere.
