1992年7月21日，德国西南部和瑞士上空的冷锋前额区域出现了一条快速移动的飑线。它向东移动并与前面的一条固定汇聚线合并。这次合并发生在一个由 14 个自动气象站组成的中尺度网络正在运行的地区，慕尼黑附近奥伯普法芬霍芬的偏振多普勒雷达对此进行了详细记录。在本文中，我们基于对雷达和表面数据以及连续无线电探空仪的分析，描述了飑线及其环境的特征。还描述了中观γ尺度特征，包括阵风锋的形成和演化。
On 21 July 1992 a fast moving squall line developed over southwestern Germany and Switzerland in the prefrontal area of a cold front. It moved eastwards and merged with a stationary convergence line ahead of it. The merger occurred in a region where a mesoscale network of 14 automatic weather stations was in operation and it was well documented by the polarimetric Doppler radar at Oberpfaffenhofen near Munchen. In this paper we describe the characteristics of the squall line and its environment based on analyses of the radar and surface data, and on serial radiosonde soundings. The meso-γ-scale features are also described including the gust-front formation and evolution.
