大气和海洋的动力学对数值建模者提出了严峻的挑战，这在很大程度上是由于所涵盖的长度和时间尺度范围广泛。基于非振荡有限体积 (NFV) 近似的现代数值方法通过再现湍流的大规模行为而无需显式的亚网格尺度模型，为缓解这一挑战提供了一种简单而有效的方法。在本文中，我们描述了特定 NFV 模型、多维正定平流传输算法的显着特性，并重点介绍了其在各种气象和湍流中的应用。
The dynamics of the atmosphere and oceans pose a severe challenge to the numerical modeler, due in large part to the broad range of scales of length and time that are encompassed. Modern numerical methods based on nonoscillatory finite volume (NFV) approximations provide a simple and effective means for mitigating this challenge by reproducing the large scale behavior of turbulent flows with no need for explicit subgrid-scale models. In this paper, we describe the remarkable properties of a particular NFV model, multidimensional positive definite advection transport algorithm, and highlight its application to a variety of meteorological and turbulent flows.
