SGER: Coupling a Slab Ocean and Sea Ice Model to the Community Atmosphere Model

PI将开发社区气候系统模型（CCSM）的简化版本（一个板块而不是完整的海洋部分）。她将研究它的平衡气候敏感性。在实践中，板状海洋模式与海冰形成高度交织，PI一直处于CCSM海冰分量开发和应用的前沿。她已经开始了这项工作，并取得了很大进展，得出了一个工作模型。这笔拨款将使她能够继续进行平板海洋模型的开发，并在维护她为CCSM帮助建立的海冰模型方面发挥积极作用。她还将使用与CCSM大气分量相耦合的平板海洋模型来明确测量模拟气候对海冰反馈的敏感性。这项工作的迫切需要在2002年6月的CCSM研讨会上得到了表达，随后得到了CCSM科学咨询委员会的认可。该项目的科学价值在于评估与海冰热力学相关的反馈如何促进气候敏感性，这是关于全球变暖辩论中的一个重要问题。这个项目更广泛的影响是为CCSM用户社区提供了一个新的功能。此外，这项开发工作将加强NCAR与大学社区之间的联系。

The PI will develop a simplified version (a slab rather than full ocean component) of the Community Climate System Model (CCSM). She will study its equilibrium climate sensitivity. In practice, a slab ocean model is highly intertwined with the sea ice formulation, and the PI has been at the forefront of the CCSM sea-ice component development and application.She has started this work and has made much progress to arrive at a working model. This grant will enable her to continue with the slab ocean model development and play an active role in maintaining the sea ice models that she helped build for the CCSM. She will also use the slab ocean model coupled to the CCSM atmospheric component to explicitly measure the sensitivity of the simulated climate to sea ice feedbacks.An immediate need for this work was expressed at the June, 2002 CCSM workshop and subsequently endorsed by the CCSM Scientific Advisory Committee.The scientific merit of this project is to evaluate how feedbacks associated with sea ice thermodynamics contribute to climate sensitivity, an important issue in the debate about global warming.The broader impact of this project is to provide a new functionality for the community of CCSM users. Also, this development effort will strengthen ties between NCAR and the university community.
