项目摘要

DMS Award AbstractAward #: 0222282PI: Thomas, StephenInstitution: University Corporation for Atmospheric ResearchProgram: Collaborations in Mathematics and the Geosciences (CMG)Program Manager: Catherine MavriplisTitle: CMG RESEARCH: An Adaptive Mesh, Spectral Element Formulation of the Well-Posed Primitive Equations for Climate and WeatherClimate simulation is a grand challenge problem requiring multiple, century-long integrations of the equations governing the Earth's atmosphere. Recently, it has been recognized that localized flow structures may play an important role in obtaining the correct climate signal. Higher-resolution climate simulations may be required in the near future at the National Center for Atmospheric Research (NCAR) and other climate modeling centers in convergence studies and to assess model uncertainty. Rather than increase resolution uniformly over the entire sphere, recent developments in adaptive mesh refinement techniques may be applicable to atmospheric general circulation models. High-order polynomial based spectral element and discontinous Galerkin methods offer the geometric flexibility required to implement adaptive methods and also exhibit the exponential convergence of the traditional spectral transform approach. The spectral element dynamical core is ideally suited to high-performance parallel computers based on microprocessors and a team at NCAR was awarded second place in the 2001 IEEE/ACM Gordon Bell competition for achieving 370 Gigaflops, representing a sustained climate simulation rate of over 100 years per day. This work represents a major advance in geophysical fluid flow simulations. By implementing an adaptive non-conforming spectral element dynamical core for atmospheric general circulation models, we propose to study how small scale flow features develop and feedback to larger scales. We also plan to study simple idealized physical forcings in this context and explore, with NCAR and university researchers, how adaptive multi-scale physical parameterizations can be implemented. Weather and climate simulation is an extremely complex problem that requires many long time computer modeling runs for the Earth's atmosphere. Recently, with the advances in computer power and with advances in the understanding of the dynamics, it has been recognized that local flow structures can play an important role in determining specific weather and climate conditions. Computer models should thus advance to fully resolve these structures in an efficient way. This project is concerned with the development of new, efficient computer models that will automatically resolve local features while providing overall accuracy. The impact on the next generation of weather and climate models should be significant.Date: June 28, 2002
DMS Award AbstractAward #: 0222282 PI: 托马斯,斯蒂芬机构: 大学大气研究公司计划: 数学与地球科学合作(CMG)项目经理:Catherine Mavriplis标题:CMG研究:气候和天气的适定性原始方程的自适应网格,谱元素公式化气候模拟是一个巨大的挑战问题,需要多个,长达一个世纪的地球大气层方程的积分。 最近,人们已经认识到,局部流动结构可能在获得正确的气候信号中发挥重要作用。在不久的将来,国家大气研究中心(NCAR)和其他气候模拟中心可能需要更高分辨率的气候模拟,以进行收敛研究和评估模型的不确定性。自适应网格细化技术的最新发展可能适用于大气环流模式,而不是在整个球体上均匀地增加分辨率。 基于高阶多项式的谱元和不连续Galerkin方法提供了实现自适应方法所需的几何灵活性,并且还表现出传统谱变换方法的指数收敛性。光谱元素动态核心非常适合基于微处理器的高性能并行计算机,NCAR的一个团队在2001年IEEE/ACM Gordon Bell竞赛中获得第二名,实现了370 Gigaflops,代表了每天超过100年的持续气候模拟速率。这项工作代表了地球物理流体流动模拟的一个重大进展。通过实现一个自适应的非一致性谱元素动力学核心的大气环流模式,我们建议研究如何小尺度流动功能的发展和反馈到更大的尺度。我们还计划在此背景下研究简单的理想化物理强迫,并与NCAR和大学研究人员一起探索如何实现自适应多尺度物理参数化。天气和气候模拟是一个极其复杂的问题,需要对地球大气进行许多长时间的计算机建模。最近,随着计算机能力的进步和对动力学的理解的进步,人们已经认识到,当地的流动结构可以在确定特定的天气和气候条件方面发挥重要作用。因此,计算机模型应该能够以有效的方式完全解析这些结构。该项目关注的是开发新的、高效的计算机模型,这些模型将自动解析局部特征,同时提供整体准确性。对下一代天气和气候模式的影响将是巨大的。日期:2002年6月28日
