This research project focuses on high-resolution simulations of the initiation of convection in the area of the planned experiment COPS of the priority programme. The mail goal is to examine the influence of the orography and surface conditions associated with the Black Forest and the Swabian Jura for the convection. The simulations will be performed using the three-dimensional non-hydrostatic model FOOT3DK, which is run for idealized studies as well as for realistic studies being nested in the operational forecast model of the DWD (local model, LM). FOOT3DK simulations will be down to a convection-resolving resolution (i.e. 1km and less). Beside process studies, the project will participate in the numerical experiments of the shortrange forecast (FC-COPS) and the virtual reality VR-COPS experiment, providing highresolution virtual measurements for the COPS experimental design for a period of several weeks. The project will contribute to a better understanding of the convection and precipitation dynamics over mesoscale low mountains.

该研究项目的重点是对优先方案计划中的COPS实验区域内的对流启动进行高分辨率模拟。主要目的是研究与黑森林和斯瓦比亚汝拉对流有关的地形和地表条件的影响。模拟将使用三维非流体静力学模型FOOT 3DK进行，该模型用于理想化研究以及DWD业务预报模型（局部模型，LM）中嵌套的现实研究。FOOT 3DK模拟将下降到对流分辨分辨率（即1公里及以下）。除了过程研究之外，该项目还将参与短期预报的数值实验（FC-COPS）和虚拟现实VR-COPS实验，为COPS实验设计提供为期数周的高分辨率虚拟测量。该项目将有助于更好地了解中尺度低山上空的对流和降水动力学。
