9731735 The objectives of this project are to improve understanding of atmospheric dynamics and to demonstrate the feasibility of numerical simulation of particular laboratory fluid flows. This grant enables a post- doctoral scientist whose expertise is in numerical simulation of geophysical fluid dynamics to collaborate with an expert in laboratory experiments in fluid flows at Cambridge, U.K. The research concentrates on two main problems of atmospheric interest. The first is to explore the effects of variable vertical forcing and variable stratification on vortices in the flow. The second is to explore the effects of large-scale horizontal shear, time-dependent forcing, and the dispersion of passive tracers. This award is in response to a proposal submitted under the guidelines of the Small Grants for Exploratory Research option because of its preliminary nature, urgency, and new, untested approach to interactive simultaneous numerical and laboratory simulation.

9731735 该项目的目标是提高对大气动力学的理解并证明特定实验室流体流动数值模拟的可行性。 这笔资助使一位专门从事地球物理流体动力学数值模拟的博士后科学家能够与英国剑桥流体流动实验室实验的专家合作。这项研究集中于大气感兴趣的两个主要问题。 第一个是探索可变垂直强迫和可变分层对流动中涡流的影响。 第二个是探索大规模水平切变、时间相关强迫和被动示踪剂分散的影响。 该奖项是对根据探索性研究小额赠款指南提交的提案的回应，因为其初步性质、紧迫性以及交互式同步数值和实验室模拟的新的、未经测试的方法。
