各种环境参数的相对重要性，在确定地形降水模式在马焦雷湖地区在欧洲阿尔卑斯山南部的一部分进行了研究。我们研究了58个长期和广泛的地形降水事件，共对应106天的降雨。中尺度风是通过多普勒速度雷达测量来估计的;气团稳定性是通过无线电探空和位于不同高度的地面站来计算的。高质量的雷达导出的地面降雨率用于表征降水场。
The relative importance of various environmental parameters in determining orographic precipitation patterns in the Lago Maggiore region in the southern part of the European Alps is investigated. We examine 58 long‐lasting and widespread orographic precipitation events corresponding in total to 106 days of rainfall. The mesoscale winds are estimated by means of Doppler velocity radar measurements; air‐mass stability is computed from both radiosoundings and pairs of ground stations located at different heights. High‐quality radar‐derived rain rates at the ground are used to characterize the precipitation field.
