在地中海水文循环实验(HyMeX)的框架内，调查了2012年10月23日的高降水事件(HPE)。早上，一个高度局部化的对流系统在科西嘉岛东南部靠近波尔图-韦奇奥的地方发展起来。6h内降水最大值可达100 mm以上，数值模拟采用水平网格间距2.5 km的MESO-NH模式。不同的输入数据集和开始时间被用来评估事件的可预测性，而这种初始条件集合的大范围表明可预测性较低。在九名乐团成员中，只有一人捕捉到了活动的时间和地点。
In the framework of the Hydrological Cycle of the Mediterranean Experiment (HyMeX), the high precipitation event (HPE) of 23 October 2012 is investigated. In the morning, a highly localized convective system developed over the southeast of Corsica, close to Porto‐Vecchio. Its precipitation maximum is estimated at over 100 mm within 6 h. The Meso‐NH model is used with a horizontal grid spacing of 2.5 km to simulate the HPE. Different input datasets and starting times are used to assess the predictability of the event and the large spread of this initial condition ensemble indicates low predictability. Among the nine ensemble members only one captures the timing and location of the event.
