9910001NicolaenkoThis three-year award for U.S.-France collaboration in applied mathematics involves Basil Nicolaenko, Harindra Fernando, Alex Mahalov and a graduate student from Arizona State University, and Igor Mezic of the University of California at Santa Barbara. The French team is led by Marie Farge at the Ecole Normale Superieure in Paris, France and includes French researchers from Grenoble, Cachan, and Lyon. The objective of the collaboration is the study of geophysical flows in fully developed turbulent regime by means of numerical simulations using adaptive pseudo-spectral and adaptive wavelet methods. Several numerical codes for different models in two to three spatial dimensions, with and without rotation, stratification and transport of passive and reactive scalars will be developed. This award represents the U.S. side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses of the U.S. investigators and graduate student. The CNRS will support the French researchers' visits to the United States. The collaboration is interdisciplinary. U.S. and French teams represent expertise in applied mathematics, fluid mechanics, meteorology and chemistry. The project will advance understanding of code development for environmental flows that have applications in air pollution, ozone depletion (in Antarctic, for example), and have a role in inertio-gravity waves in the stratosphere.

9910001 Nicolaenko这一为期三年的美国-法国合作应用数学涉及巴兹尔Nicolaenko，Harindra费尔南多，亚历克斯Mahalov和一名研究生从亚利桑那州州立大学，和伊戈尔Mezic的加州大学在圣巴巴拉。 法国研究小组由法国巴黎高等师范学校的玛丽法格领导，成员包括来自格勒诺布尔、卡尚和里昂的法国研究人员。 合作的目的是通过使用自适应伪谱和自适应小波方法进行数值模拟，研究充分发展的湍流状态下的地球物理流动。 将为二至三维空间的不同模型开发几个数值代码，包括有无旋转、分层和被动和反应标量的传输。 该奖项代表了美国方面向NSF和法国国家科学研究中心（CNRS）提出的联合建议。 NSF将承担美国研究人员和研究生的旅费和生活费。 CNRS将支持法国研究人员访问美国。 合作是跨学科的。美国和法国代表团代表了应用数学、流体力学、气象学和化学方面的专业知识。 该项目将促进对环境流动编码开发的理解，这些流动可应用于空气污染、臭氧消耗（例如在南极），并在平流层惯性重力波中发挥作用。
