Simulation of topography-induced convection in the COPS area (STICCA)

本研究项目的重点是在优先方案的计划实验COPS区域内对流开始的高分辨率模拟。主要目标是研究与黑森林和斯瓦本汝拉有关的地形和地表条件对对流的影响。模拟将使用三维非流体静力模型FOOT3DK进行，该模型可用于理想研究，也可用于嵌套在DWD操作预测模型（局部模型，LM）中的实际研究。FOOT3DK模拟将降低到对流分辨分辨率（即1公里或更少）。除过程研究外，本项目还将参与短期预报数值实验（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区的对流和降水动力学。

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.
