Collaborative Research: Gravity Current Entrainment Climate Process Team Renewal

0611572这是一个气候过程试验小组的延续，该小组开发重力流夹带的参数，以包括在海洋环流模式中。我们的团队包括参与最近溢流卷吸作用现场研究的观测人员：(法罗海岸海峡、南极陆架、红海溢流)；用高分辨率非静力模拟检查卷吸过程的过程研究模型师；重力流卷吸简化模型的开发者；以及在海洋机构和气候模拟中心使用各种大型模型架构的人员。该项目最后两年的主要目标是：(A)密切审查观测和过程研究中的夹带；(B)利用这一知识开发新的夹带参数；(C)在海洋环流模式和耦合气候模式中实施和评价新的参数。拟议活动的学术价值：重力流卷吸是海洋气候环流的重要组成部分，这项研究将加强我们对这一过程及其在气候中的作用的理解。广泛影响：这项研究将加强模拟中心和学术机构之间的联系；以新的参数化形式提供具体产品，可供整个气候模拟社区使用。它将使社会受益于能够更可靠地预测气候变化，并通过资助来自代表性不足群体的2名博士后和调查人员来促进跨学科培训。研究结果将通过更大社区的年度研讨会传播。该项目是对美国CLIVAR(气候可变性和可预测性)计划的贡献。

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.
