本文的目的是描述对流允许数值天气预报（NWP）模式HARMONIE-AROME的参考配置，该模式用于丹麦、爱沙尼亚、芬兰、冰岛、爱尔兰、立陶宛、荷兰、挪威、西班牙和瑞典的业务短期天气预报。它是欧洲和北方非洲26个国家在短程中尺度数值预报方面合作开发、维护和验证的，作为ALADIN-HIRLAM共享系统的一部分。HARMONIE-AROME基于ALADIN联盟开发的AROME模型。沿着联合建模框架，上述国家在北方和南欧条件下实施和使用了AROME，这一活动导致了对模型物理参数化的广泛更新。在本文中，作者提出的差异模式动力学和物理参数化相比，AROME，以及重要的配置选择的参考，如横向边界条件，模式水平，水平分辨率，模式的时间步长，以及地形，自然地理和气溶胶数据库使用。将为所使用的大气和地面数据同化算法和观测类型提供单独的文件，并单独说明基于HARMONIE-AROME的集合预报系统，称为HarmonEPS。
The aim of this article is to describe the reference configuration of the convection-permitting numerical weather prediction (NWP) model HARMONIE-AROME, which is used for operational short-range weather forecasts in Denmark, Estonia, Finland, Iceland, Ireland, Lithuania, the Netherlands, Norway, Spain, and Sweden. It is developed, maintained, and validated as part of the shared ALADIN-HIRLAM system by a collaboration of 26 countries in Europe and northern Africa on short-range mesoscale NWP. HARMONIE-AROME is based on the model AROME developed within the ALADIN consortium. Along with the joint modeling framework, AROME was implemented and utilized in both northern and southern European conditions by the above listed countries, and this activity has led to extensive updates to the model's physical parameterizations. In this paper the authors present the differences in model dynamics and physical parameterizations compared with AROME, as well as important configuration choices of the reference, such as lateral boundary conditions, model levels, horizontal resolution, model time step, as well as topography, physiography, and aerosol databases used. Separate documentation will be provided for the atmospheric and surface data-assimilation algorithms and observation types used, as well as a separate description of the ensemble prediction system based on HARMONIE-AROME, which is called HarmonEPS.
