Table 2: Maximum values (in mm) and the distance separating these maxima to their RADOME counterparts (in km) for the April and June cases. These values were determined considering the different stations inside the delimitated areas shown in Figure 2c: WMC for the western Massif Central, SAL for the south of the Alps, DUR for Durance, CEV for Cévenues, JUR for Jura, and NMC for the northern Massif Central. \begin{table}

For the June event, PANTHERE detected a localized high-intensity precipitation pattern over the north of the Massif Central (NMC area) extended on a southwest-northeast axis (Figure 4b), as RADOME. The maximum of precipitation accumulation estimated by PANTHERE over NMC was 204.60 mm and was located 74.64 km away from the rain maximum captured by RADOME (Table 2). However, the median of the rain accumulation for the NMC area (35.0 mm) was close to the RADOME one (35.7 mm) for this event. We can see that the main differences in the rain distribution between RADOME and PANTHERE were, as for the April case, located over the reliefs of the Massif Central area (Figure 4d).
