项目摘要

In the coastal desert Namib in southern Africa, the occurrence of fog is of great importance not only for the ecological system, but also for the production of potable water by means of fog water collectors. To enable the construction of economic fog water collection systems, detailed knowledge of the spatio-temporal development of fog events is inevitable. Due to the complex topographical structure in the Namib area, this knowledge can only be achieved by means of numerical simulations.The major goal of the present project consists in the development of the three-dimensional numerical fog model COSMO-FOG. This development will be based on the mesoscale weather prediction model COSMO. For the numerical simulations of fog events in the Namib region it will be of particular importance to consider in COSMO-FOG the special topographical situation in the investigation area (Atlantic ocean, coastal desert, Great Escarpment) so that realistic simulations of the different fog events in this area, \ie advection fog, radiation fog, lowering stratus, will be possible. The proposed project is part of a package consisting of three single projects, that is the present project (NaFoLiCa-M), field measurements (NaFoLiCa-F) as well as the analysis of fog events by means of remote sensing systems (NaFoLiCa-S). With these three projects it will be possible to obtain comprehensive knowledge about the spatio-temporal evolution of fog in the Namib region which is of great importance for a successful and efficient use of fog water.

在南部非洲的沿海沙漠纳米布，雾的出现不仅对生态系统非常重要，而且对通过雾水收集器生产饮用水也非常重要。为了使经济的雾水收集系统的建设，雾事件的时空发展的详细知识是不可避免的。由于纳米布地区复杂的地形结构，这方面的知识只能通过数值模拟来实现。本项目的主要目标是开发三维数值雾模式COSMO-FOG。这一发展将以中尺度天气预报模式COSMO为基础。对于纳米布地区雾事件的数值模拟，在COSMO-FOG中考虑调查区域的特殊地形情况（大西洋、沿海沙漠、大陡崖）将是特别重要的，以便能够真实地模拟该区域的不同雾事件，即平流雾、辐射雾、降低层云。拟议的项目是由三个单独项目组成的一揽子计划的一部分，即本项目（NaFoLiCa-M），实地测量（NaFoLiCa-F）以及通过遥感系统分析雾事件（NaFoLiCa-S）。通过这三个项目，将有可能获得有关纳米布地区雾的时空演变的全面知识，这对于成功和有效地利用雾水具有重要意义。
