北大西洋波导管和下游撞击实验（NAWDEX）通过部署四架研究飞机探索非绝热过程对急流扰动的影响及其对下游高影响天气的影响，每架飞机都配备了一套先进的遥感和现场仪器，并与一套地面测量相协调。共进行了49次研究飞行，包括首次四架飞机的协调飞行：德国高空和远程研究飞机（HALO）、德国航空航天中心（DLR）达索猎鹰20号、法国环境研究仪器服务公司（SAFIRE）猎鹰20号，和英国机载大气测量设施（FAAM）BAe 146。2016年9月17日至10月22日的观测期间，经常发生热带气旋和热带气旋，是研究北大西洋中纬度天气的理想选择。NAWDEX展示了波导扰动的三个上游触发序列，以及它们与急流的动态相互作用，随后的发展以及最终对欧洲的下游天气影响。举例突出了被抽样的现象的财富，全面的覆盖面，以及测量的多方面性质。这一独特的数据集构成了未来案例研究和详细评估天气和气候预测的基础，以提高我们对非绝热对Rossby波的影响以及影响欧洲的天气系统的下游影响的理解。
The North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) explored the impact of diabatic processes on disturbances of the jet stream and their influence on downstream high-impact weather through the deployment of four research aircraft, each with a sophisticated set of remote sensing and in situ instruments, and coordinated with a suite of ground-based measurements. A total of 49 research flights were performed, including, for the first time, coordinated flights of the four aircraft: the German High Altitude and Long Range Research Aircraft (HALO), the Deutsches Zentrum für Luft- und Raumfahrt (DLR) Dassault Falcon 20, the French Service des Avions Français Instrumentés pour la Recherche en Environnement (SAFIRE) Falcon 20, and the British Facility for Airborne Atmospheric Measurements (FAAM) BAe 146. The observation period from 17 September to 22 October 2016 with frequently occurring extratropical and tropical cyclones was ideal for investigating midlatitude weather over the North Atlantic. NAWDEX featured three sequences of upstream triggers of waveguide disturbances, as well as their dynamic interaction with the jet stream, subsequent development, and eventual downstream weather impact on Europe. Examples are presented to highlight the wealth of phenomena that were sampled, the comprehensive coverage, and the multifaceted nature of the measurements. This unique dataset forms the basis for future case studies and detailed evaluations of weather and climate predictions to improve our understanding of diabatic influences on Rossby waves and the downstream impacts of weather systems affecting Europe.
