Convective precipitation trends in the Spanish Mediterranean region

This paper aims to analyse the distribution and temporal evolution of convective precipitation in Mediterranean region Spain. To accomplish this goal, we used 148 sets 5-min rainfall rate data from 1989–2015 period. The selected regions were Júcar Hydrographic Confederation (CHJ) Internal Basins Catalonia (CIC), which cover most autonomous communities Valencian Community (east Spain). average intensity threshold 35 mm/h ? parameter, defined as ratio between versus total any period, characterise precipitation. Convective episodes categorised “very convective”, “moderately “slightly convective” based on value. After quality control, series 129 stations clustered into homogeneous zones that also include one variables characterisation. results show can contribute annual by up 16% average, but it is generated a very small percentage events (between 3% 6% across all stations) comparison with number episodes.
