The new KITsonde multi-sensor dropsonde will have its first operational use aboard HALO for investigation of deep convection and cyclones causing High Impact Weather (HIW) in the Mediterranean during the Demonstration Mission NEPTUN in autumn 2012. Following a sequence of three days of the development of an upper tropospheric trough leading to deep convection, mesoscale convective systems, and a lower tropospheric cyclone with embedded convection, the KITsonde will be used on the one hand to detect the variability of wind temperature and humidity prior to the cyclogenesis upstream, combined with in-situ and lidar remote sensing instruments. On the other hand during the final stage of HIW development, KITsonde will provide high resolution in-situ measurements from the inside of convective cells and MCS, inaccessible for the aircraft and optical remote sensing instruments. This dataset will allow the analysis of the variability of wind, temperature and humidity in time and space on all affecting scales, responsible for vertical fluxes of energy, which themselves are decisive for the initiation of convection - an important trigger mechanism for HIW. The impact of additional high resolution profiles within convective systems on the forecast quality of the NWF model COSMO-DE will be investigated.

新型 KIT 多传感器下投式探空仪将在 2012 年秋季 NEPTUN 示范任务期间在 HALO 上首次投入使用，用于调查造成地中海高影响天气 (HIW) 的深对流和气旋。经过为期三天的开发上层对流层槽导致深对流、中尺度对流系统和带有嵌入式对流的下层对流层气旋，一方面，KIT探空仪将与现场和激光雷达遥感仪器相结合，用于检测上游气旋形成之前的风温和湿度变化。另一方面，在 HIW 开发的最后阶段，KITsonde 将从对流单元和 MCS 内部提供高分辨率原位测量，这是飞机和光学遥感仪器无法访问的。该数据集将允许分析所有影响尺度上风、温度和湿度在时间和空间上的变化，负责能量的垂直通量，这本身对于对流的启动具有决定性作用，对流是 HIW 的重要触发机制。将研究对流系统内额外高分辨率剖面对 NWF 模型 COSMO-DE 预报质量的影响。
