KONTROL 1984 - First Experiment on Convection and Turbulence over the North Sea: radiosoundings at the research vessel Valdivia

Project: Field Data of the Meteorological Institute, University of Hamburg - The Physical Meteorology Division of the Meteorological Institute is regularly conducting or taking part in field experiments with strong focus on high latitudes. Measurements are performed by aircraft, radiosondes or buoys and at land, ship and ice stations. Published data sets incorporate aircraft measurements of turbulent fluxes and standard meteorological parameters of high temporal and spatial resolution. These measurements are supported by frequent radiosonde ascents and station and ship data in the according region. Another group of data sets consists of measurements by autonomous buoys of different complexity on sea ice and ocean. Summary: KONTROL 1984 is part of research activities focused on organized convection phenomena as they are often manifested in organized cloud patterns like the well-known boundary layer cloud streets or open and closed cellular cloud structures. The experimental part of the investigations began with the experiment KonTur (Konvektion and Turbulenz) in September and October 1981. It continued with the experiments KONTROL in August 1984 and KONTROL in October 1985. All experiments took place over the German Bight in the southeastern part of the North Sea. The experimental concept based on the use of two fixed stations performing continuous aerological and surface observations and two aircraft conducting detailed observations during special periods. The stations were the research vessel Valdivia and the research platform NORDSEE (54°42'N, 7°10'E). The aircraft were a FALCON-20 of DFVLR and a DO-28 Skyservant of the TU Braunschweig.

项目：汉堡大学气象研究所野外数据集——汉堡大学气象研究所物理气象学部定期开展或参与以高纬度地区为核心研究对象的野外试验。试验测量工作通过飞机、无线电探空仪（radiosondes）、浮标（buoys）完成，观测站点涵盖地面站、船舶站与冰站。已公开的数据集包含高时空分辨率的飞机湍流通量测量数据与标准气象参数数据，此类测量辅以该区域内高频次的无线电探空升空观测、地面站与船舶观测数据。另一类数据集则由不同复杂度的自主浮标在海冰与海洋环境中采集得到。摘要：KONTROL 1984项目聚焦于组织化对流现象——这类现象常以组织化云型呈现，例如广为人知的边界层云街，或是开放、封闭胞状云结构。相关研究的试验阶段始于1981年9月至10月的KonTur（对流与湍流）试验，后续延续为1984年8月的KONTROL试验与1985年10月的KONTROL试验。所有试验均在北海东南部的德国湾（German Bight）海域开展。本次试验方案依托两个固定观测站开展连续高空与地面观测，并在特定时段由两架飞机开展精细化观测：两个固定观测站分别为“瓦尔迪维亚”号科考船与北森（NORDSEE）号科考平台（54°42'N, 7°10'E）；参与试验的飞机分别为DFVLR的FALCON-20型飞机，以及布伦瑞克工业大学（TU Braunschweig）的DO-28 Skyservant型飞机。
