Precipitation dynamics in Corsica will be investigated to unveil the interplay between local breeze Systems, large-scale circulation and topography. A classification of typical precipitation weather types affecting the Corsica region will be applied to account for the large- and local-scale (coupled land/sea/mountain breeze systems) influence. The local-scale characteristics and the interplay will be analysed with special reference to the development of the planetary boundary layer (PBL) as a discriminating proxy between the surface affected and the free atmosphere. Along an altitudinal transect from west to east, measurements of meteorological parameters will provide temporal high resolution precipitation and PBL information at different heights and expositions. Further, based on high resolution spatial-explicit cloud and precipitation maps derived from remote-sensing and ground-based observations the diurnal cycle of precipitation dynamics for entire Corsica related to the defined weather types will be examine. The underlying mechanisms as well as the cross-scale processes of PBL development and precipitation formation will be reflected in high resolution numerical modelling simulations. With the application of back-trajectory modelling sources and pathways of atmospheric vapour for the precipitation generation will be investigated, which may enable a proper interpretation of d18O measurements in the Corsican archives (water and tree rings).

将研究科西嘉的降水动力学，以揭示当地微风系统、大尺度环流和地形之间的相互作用。将对影响科西嘉地区的典型降水天气类型进行分类，以说明大尺度和局部尺度（耦合陆地/海洋/山风系统）的影响。将分析当地尺度的特征和相互作用，特别是行星边界层的发展，作为受影响表面和自由大气之间的区别代理。沿沿着由西向东的垂直样带，气象参数的测量将提供不同高度和暴露量的时间高分辨率降水和边界层信息。此外，基于高分辨率的空间明确的云和降水地图来自遥感和地面观测的降水动态的日周期为整个科西嘉有关的定义的天气类型将进行检查。边界层发展和降水形成的基本机制以及跨尺度过程将在高分辨率数值模拟中得到反映。与应用程序的后向轨迹建模的来源和途径的大气蒸汽的降水生成将进行调查，这可能会使一个正确的解释d18 O测量科西嘉档案（水和树木年轮）。
