ABSTRACTOCE-0611572This is a continuation of a pilot Climate Process Team to develop parameterizations of gravity current entrainment for inclusion in ocean general circulation models. Our team comprises observationalists involved in recent field studies of entrainment in overflows: (Faroe Bank Channel, Antarctic shelf, Red Sea Overflow); process study modelers examining entrainment processes with high resolution non-hydrostatic simulations; developers of simplified models of entraining gravity currents ; and those using a variety of large scale model architectures at oceanographic institutions and climate modeling centers. The main objective of the final two years fo the project are to (a) closely examine entrainment in observations and process studies; (b) use this knowledge to develop new parameterizations of entrainment; (c) implement and evaluate the new parameterizations in ocean general circulation models and coupled climate models. Intellectual merit of the proposed activity: Gravity current entrainment is an important component of the ocean climate circulation, and this study will enhance our understanding of this process and its role in the climate.Broader impacts: This study will enhance links between modeling centers and academic institutions; provide concrete products in the form of new parameterizations which can be used by the whole climate modeling community. It will benefit society by enabling more reliable predictions of climate variability and promote interdisciplinary training through funding of 2 postdocs and investigators from under-represented groups. The results of the research will be disseminated through annual workshops involving the larger community.This project is a contribution to the U.S. CLIVAR (CLImate VARiability and predictability) program.

ABSTRACTOCE-0611572这是试点气候过程团队的延续，旨在开发重力流夹带参数化以纳入海洋环流模型。我们的团队由参与近期溢流夹带实地研究的观察家组成：（法罗浅滩海峡、南极大陆架、红海溢流）；过程研究建模人员通过高分辨率非静水模拟检查夹带过程；夹带重力流简化模型的开发者；以及那些在海洋学机构和气候建模中心使用各种大型模型架构的人。该项目最后两年的主要目标是（a）仔细检查观察和过程研究中的夹带； (b) 利用这些知识来开发新的夹带参数化； (c) 实施和评估海洋环流模型和耦合气候模型中的新参数化。拟议活动的智力价值：重力流夹带是海洋气候环流的重要组成部分，这项研究将增强我们对这一过程及其在气候中的作用的理解。更广泛的影响：这项研究将加强建模中心和学术界之间的联系机构；提供新参数化形式的具体产品，可供整个气候建模界使用。它将通过更可靠地预测气候变化来造福社会，并通过资助 2 名博士后和来自代表性不足群体的研究人员来促进跨学科培训。研究结果将通过涉及更大社区的年度研讨会进行传播。该项目是对美国 CLIVAR（气候变异性和可预测性）计划的贡献。
