ABSTRACTOCE-0611486This 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-0611486这是试验气候过程团队的延续，以开发重力电流夹带的参数，以包含在海洋一般循环模型中。我们的团队包括参与最近涉及溢出夹带的现场研究的观察主义者：（法罗银行频道，南极架子，红海溢流）；工艺研究建模者检查具有高分辨率非静态模拟的夹带过程；简化重力电流模型的开发人员；以及在海洋学机构和气候建模中心使用各种大型模型体系结构的人。该项目的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）使用这些知识来开发夹带的新参数； （c）在海洋通用循环模型和耦合气候模型中实施和评估新的参数化。拟议活动的智力优点：重力电流夹带是海洋气候循环的重要组成部分，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。BROADER的影响：这项研究将增强建模中心与学术机构之间的联系；以新的参数化形式提供混凝土产品，并由整个气候建模社区使用。它将通过对气候变异性的更可靠的预测进行更可靠的预测来使社会受益，并通过资助来自代表性不足的群体的2个博士后和调查人员来促进跨学科培训。该研究的结果将通过涉及较大社区的年度研讨会来传播。该项目是对美国Clivar（气候可变性和可预测性）计划的贡献。
