XVIII Alpine Summer School on Buoyancy-Drive Flows

浮力是驱动地球上水流的主要力量之一，尤其是在海洋和大气中。浮力驱动的流动涵盖了广泛的地球物理流动，从浮力的沿海洋流到海洋中的密集溢出，从雪崩到地球表面的火山火山碎屑流。在海洋中，浮力沿海洋流沿着许多大陆架输送淡水、热量、营养物质、沉积物、生物地球化学物质、污染物和生物有机体，因此对生态系统、渔业和沿海环流产生重要影响。名为“浮力驱动流动”的第十八届高山暑期学校将于2010年6月20日至7月1日在意大利奥斯塔举行。该学院的联合主任将是：Claudia Cenedese (WHOI)；Eric Chassignet (FSU)；和Jacques Verron （INPG）。暑期学校将持续10天，约有10位受邀演讲者，每位演讲者将进行2至3次教学讲座。除正式讲座外，还将由一些其他高级与会者举办较短的“研究研讨会”。与会者还将有机会通过海报展示他们的工作，并参加关于浮力驱动的气候流动重要性的辩论。虽然计划有一系列强调海洋的讲座，但也打算讨论更广泛的地球物理问题（雪崩、火山流、大气流等）。目的是收集课堂讲稿并出版成书。知识价值：讲座将首先对浮力驱动流的最新研究进行广泛的概述，并将在更广泛的地球物理问题（雪崩，火山流，大气流等）的背景下进行。然后，更具体的讲座将侧重于正确表示气候模式中海洋部分目前尚未解决的过程的重要性。考虑到浮力流对海洋环流和地球气候的影响，将顶尖科学家聚集在一起总结目前对浮力流的理论、实验和建模理解是及时的。更广泛的影响：学校的一个具体目标是从理论、实验和建模的角度，让年轻的研究生和最近的博士学位获得者了解海洋环流和当今气候中浮力驱动的流动的重要性。此外，课堂讲稿将作为教科书出版。

Buoyancy is one of the main forces driving flows on our planet, especially in the ocean and atmosphere. Buoyancy driven flows encompass a wide spectrum of geophysical flows that range from buoyant coastal currents to dense overflows in the ocean, and from avalanches to volcanic pyroclastic flows on the Earth's surface. In the ocean, buoyant coastal currents transport fresh water, heat, nutrients, sediments, biogeochemicals, pollutants, and biological organisms along many continental shelves and, hence, have important impacts on ecosystems, fisheries, and the coastal circulation.The XVIII Alpine Summer School entitled 'Buoyancy-Driven Flows' will be held in Aosta, Italy, from June 20 to July 1, 2010. The Co-directors of the school will be: Claudia Cenedese (WHOI); Eric Chassignet (FSU); and Jacques Verron (INPG). The summer school will last 10 days with approximately 10 invited speakers, each presenting 2 or 3 pedagogical lectures. In addition to formal lectures, shorter 'research seminars' will be given by a few additional senior participants. Attendees will also have the opportunity to present their work via poster sessions and to participate in a debate on the importance of buoyancy-driven flows in climate. While it is planned to have a series of lectures with a strong emphasis on the ocean, it is also intended to discuss a wider range of geophysical problems (avalanches, volcanic flows, atmospheric flows, etc.). The intention is to collect the lecture notes and publish them in a book. Intellectual Merit: The lectures will first give a broad overview of the current state-of-the-art research in buoyancy-driven flows and will be put in the context of a wider range of geophysical problems (avalanches, volcanic flows, atmospheric flows, etc.). Then, more specific lectures will focus on the importance of correctly representing processes than are not currently resolved in the ocean component of climate models. Given the impact of buoyancy flows on the ocean circulation and the Earth's climate, it is considered timely to bring together leading scientists to summarize the present theoretical, experimental, and modeling understanding of buoyancy-driven flows.Broader Impact: One specific objective of the school is to expose young graduate students and recent Ph.D. recipients to the importance of buoyancy-driven flows in the ocean circulation and in the present day climate, from a combined theoretical, experimental, and modeling point of view. Furthermore, the lecture notes will be published as a text book.
