近50年来，大涡模拟技术已发展成为研究大气边界层输运过程最重要的数值工具之一。本文综述了该技术作为ABL研究工具的发展，与最先进的科学计算资源的集成，以及一些关键应用领域。对已发表文献的分析表明，LES研究从1990年前后开始在广泛的应用领域加速发展。从那时起，在几个不同的应用领域开展了强有力的研究，并在回顾发表在本杂志上的论文的基础上，我们确定了七个主要的ABL-LES研究领域：对流边界层、稳定边界层、过渡边界层、植物冠层流动、城市气象和弥散、地表异质性以及亚网格尺度（SGS）模型的测试和开发。我们从LES的总体概述开始，然后继续检查为ABL-LES中使用而开发的SGS模型。在对该技术本身进行概述之后，我们将回顾针对已确定的应用领域量身定制的特定模型开发，以及在每个领域使用LES技术实现的科学进步。最后，我们检查了已发表的ABL-LES研究的计算趋势，并确定了一些资源利用不足的情况。未来的发展方向和研究需求是通过对综述文献的综合来确定的。
Over the last 50 years the large-eddy simulation (LES) technique has developed into one of the most prominent numerical tools used to study transport processes in the atmospheric boundary layer (ABL). This review examines development of the technique as a tool for ABL research, integration with state-of-the-art scientific computing resources, and some key application areas. Analysis of the published literature indicates that LES research across a broad range of applications accelerated starting around 1990. From that point in time, robust research using LES developed in several different application areas and based on a review of the papers published in this journal, we identify seven major areas of intensive ABL–LES research: convective boundary layers, stable boundary layers, transitional boundary layers, plant canopy flows, urban meteorology and dispersion, surface heterogeneity, and the testing and development of subgrid-scale (SGS) models. We begin with a general overview of LES and then proceed to examine the SGS models developed for use in ABL–LES. After this overview of the technique itself, we review the specific model developments tailored to the identified application areas and the scientific advancements realized using the LES technique in each area. We conclude by examining the computational trends in published ABL–LES research and identify some resource underutilization. Future directions and research needs are identified from a synthesis of the reviewed literature.
