XVIII Alpine Summer School on Buoyancy-Drive Flows

浮力是推动地球上水流的主要力量之一，特别是在海洋和大气中。浮力驱动的流动包括范围广泛的地球物理流动，从漂浮的沿海洋流到海洋中的密集溢流，从雪崩到地球表面的火山火山碎屑流。在海洋中，漂浮的海岸洋流沿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、渔业和海岸循环产生重要影响。第十八届阿尔卑斯山夏季学校题为“浮力驱动的水流”，将于2010年6月20日至7月1日在意大利奥斯塔举行。该学院的联席董事将是：克劳迪娅·塞内迪斯(WHOI)、埃里克·查西格内特(FSU)和雅克·韦伦(Jacques Verron)。暑期班将持续10天，约10名受邀演讲者，每人讲授2到3场教育学讲座。除了正式的讲座外，还将有几位高级学员举办较短的“研究研讨会”。与会者还将有机会通过海报会议介绍他们的工作，并参与关于气候中浮力驱动的流动的重要性的辩论。虽然计划举办一系列以海洋为重点的讲座，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)。其目的是收集课堂讲稿，并将其出版成书。学术价值：这些讲座将首先对浮力驱动的流动的最新研究进行广泛概述，并将放在更广泛的地球物理问题(雪崩、火山流、大气流动等)的背景下进行讨论。然后，更具体的讲座将集中在正确表示过程的重要性上，而不是目前气候模型的海洋部分中尚未解决的问题。考虑到浮力流动对海洋环流和地球气候的影响，现在是时候召集顶尖科学家来总结目前对浮力驱动流动的理论、实验和建模方面的理解。广泛影响：该学院的一个具体目标是从理论、实验和建模相结合的角度，让年轻的研究生和最近的博士生了解浮力驱动流动在海洋环流和当今气候中的重要性。此外，课堂讲稿将作为课本出版。

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.
