The wind field in Arctic fjords is strongly influenced by glaciers, local orography and the interaction between sea and land. Ny-Ålesund, an important location for atmospheric research in the Arctic, is located in Kongsfjorden, a fjord with a complex local wind field that influences measurements in Ny-Ålesund. Using wind measurements from UAS (unmanned aircraft systems), ground measurements, radiosonde and reanalysis data, characteristic processes that determine the wind field around Ny-Ålesund are identified and analysed. UAS measurements and ground measurements show, as did previous studies, a south-east flow along Kongsfjorden, dominating the wind conditions in Ny-Ålesund. The wind measured by the UAS in a valley 1 km west of Ny-Ålesund differs from the wind measured at the ground in Ny-Ålesund. In this valley, we identify a small-scale catabatic flow from the south to south-west as the cause for this difference. Case studies show a backing (counterclockwise rotation with increasing altitude) of the wind direction close to the ground. A katabatic flow is measured near the ground, with a horizontal wind speed up to 5 m s^-1. Both the larger-scale south-east flow along the fjord and the local katabatic flows lead to a highly variable wind field, so ground measurements and weather models alone give an incomplete picture. The comparison of UAS measurements, ground measurements and weather conditions analysis using a synoptic model is used to show that the effects measured in the case studies play a role in the Ny-Ålesund wind field in spring.

北极峡湾的风场受冰川、当地地形和海陆相互作用的强烈影响。新奥勒松 (Ny-Ålesund) 是北极大气研究的重要地点，它位于孔斯峡湾 (Kongsfjorden)，该峡湾具有复杂的局部风场，影响新奥勒松 (Ny-Ålesund) 的测量。使用来自 UAS（无人驾驶飞机系统）的风测量、地面测量、无线电探空仪和再分析数据，确定和分析了确定新奥勒松周围风场的特征过程。UAS 测量和地面测量显示，与之前的研究一样，沿 Kongsfjorden 的东南气流主导了新奥勒松的风力条件。UAS 在新奥勒松以西 1 公里的山谷中测得的风与在新奥勒松地面测得的风不同。在这个山谷里，我们确定从南部到西南的小规模缓和流是造成这种差异的原因。案例研究显示了靠近地面的风向逆时针旋转（随着高度的增加逆时针旋转）。在地面附近测量下降流，水平风速高达 5 毫秒^-1。峡湾沿线的大规模东南气流和当地的下降气流都会导致风场高度变化，因此仅靠地面测量和天气模型无法提供完整的图像。使用天气模型对无人机测量、地面测量和天气条件分析进行比较，表明案例研究中测量的影响在春季的新奥勒松风场中发挥了作用。
