Saturn s largest moon Titan is surrounded by a thick nitrogen-rich atmosphere with an Earth-like thermal structure. Titan s atmosphere represents an outstanding natural laboratory to investigate the meteorology in the context of comparative planetology. Comprehensive atmospheric models such as general circulation models (GCMs) have already contributed much to the understanding of how Titan s atmospheric engine may be working, but the scarcity of data from the lower atmosphere and surface often caused ambiguity in the data interpretation. The ongoing Cassini/Huygens mission at Titan is beginning to unveil the enigma of the lower atmosphere and opens new perspectives in the exploration of Titan s atmosphere and surface. The proposed investigation aims at understanding the observed data concerning the dynamic meteorology of Titan and its implication for Titan s surface and exogeneous geology. The study comprises a major update of the existing GCM with Cassini/Huygens data, investigating the possible mechanism of the observed wind profile and the interaction between the surface and atmosphere as well as benchmarking of existing Titan GCMs.

土星最大的卫星泰坦被厚厚的富氮大气层所包围，具有类似地球的热结构。土卫六的大气层代表了一个杰出的天然实验室，可以在比较行星学的背景下研究气象学。全面的大气模型，如大气环流模型（GCM），已经为理解土卫六的大气发动机如何工作做出了很大贡献，但是来自低层大气和地表的数据的稀缺往往导致数据解释的模糊性。正在进行的卡西尼/惠更斯使命在土卫六开始揭开低层大气之谜，并开辟了新的视角，在探索土卫六的大气和表面。拟议的调查旨在了解有关土卫六的动态气象观测数据及其对土卫六表面和外生地质的影响。这项研究包括利用卡西尼/惠更斯号数据对现有的大气环流模型进行重大更新，调查观测到的风廓线的可能机制和地面与大气之间的相互作用，以及对现有的土卫六大气环流模型进行基准测试。
