在本文中，我们提出了当前版本的简化大涡模拟模式（PALM）的核心已经在气象和气候研究所在汉诺威（德国）莱布尼茨大学开发。PALM是一个基于Fortran 95的代码，带有一些Fortran 2003扩展，已应用于各种大气和海洋边界层的模拟超过15年。PALM被优化用于大规模并行计算机架构，最近被移植到通用图形处理单元。在本论文中，我们给出了一个详细的描述，目前版本的模型及其功能，如嵌入式拉格朗日云模型和使用笛卡尔地形的可能性。此外，我们讨论了最近的模型发展和未来的前景LES应用。
In this paper we present the current version of the Parallelized Large-Eddy Simulation Model (PALM) whose core has been developed at the Institute of Meteorology and Climatology at Leibniz Universitat Hannover (Germany). PALM is a Fortran 95-based code with some Fortran 2003 extensions and has been applied for the simulation of a variety of atmospheric and oceanic boundary layers for more than 15 years. PALM is optimized for use on massively parallel computer architectures and was recently ported to general-purpose graphics processing units. In the present paper we give a detailed description of the current version of the model and its features, such as an embedded Lagrangian cloud model and the possibility to use Cartesian topography. Moreover, we discuss recent model developments and future perspectives for LES applications.
