Simulation of Turbulence in Rotating, Stratified Flows

9731735该项目的目的是增进对大气动力学的了解，并证明对特定实验室流体流动进行数值模拟的可行性。这项资助使一位专攻地球物理流体动力学数值模拟的博士后科学家能够与一位在英国剑桥大学从事流体流动实验室实验的专家合作。这项研究集中在两个主要的大气问题上。首先是探讨变垂直强迫和变分层对流动中涡的影响。二是探索大尺度水平剪切、时间相关强迫和被动示踪剂弥散的影响。该奖项是对根据探索性研究小额拨款的指导方针提交的提案的回应，因为它的初步性质、紧迫性和新的、未经测试的交互式同步数值和实验室模拟方法。

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.
