Antarctic Clouds and Climate

Lubin, Dan Walden, Von Bromwich， David加利福尼亚大学，威斯康星大学俄亥俄州立大学圣地亚哥分校：南极云与气候提议的工作将研究南极云在全球气候系统中的作用。建议在NCAR CCM3中增加模拟南极云的真实感。将对卫星和地面观测资料进行分析，以加强对南极云层的了解。在此基础上，将在模型中实施一些更改；这些变化的本地和远程影响将通过CCM3敏感性运行进行研究。该研究将使CSM产生更真实的大气变率，并更好地模拟气候变化情景下南大洋的海冰行为和相关的热盐环流。这项工作很重要，因为它将有助于更好地模拟南大洋的过程。

Abstract ATM-9814151 ATM-9820043 ATM-9820042 Lubin, Dan Walden, Von Bromwich, David University of California, University of Wisconsin Ohio State University San DiegoTitle: Antarctic Clouds and ClimateThe proposed work will study the role of Antarctic clouds in the global climate system. It is proposed to increase the realism of simulated Antarctic clouds in the NCAR CCM3. Satellite and ground-based observations will be analyzed to enhance the understanding of Antarctic clouds. On the basis of these, a number of changes will be implemented in the model; the local and remote impacts of these changes will be examined by conducting CCM3 sensitivity runs. The study will result in the CSM producing more realistic atmospheric variability as well as better simulation of sea ice behavior and associated thermohaline circulation of the Southern Ocean in climate change scenarios. The work is important because it will lead to better modeling of processes in the Southern Oceans.
