Variations in Seasonal Precipitation Regime According to the Elevation

Catalonia has a Mediterranean climate with intense, long drought or rainy periods, which are difficult to manage. The variable topographic and sea conditions also contribute to modulating the extreme atmospheric regime. The aim of this research is to model the precipitation regime of the region based on different radar and lightning fields. To conduct the analysis, several points have been selected with different heights to evaluate the monthly values and establish the common yearly patterns. It has been observed that there are two principal behaviours: single and double maxima modes. Single peak usually occurs during warm months (mainly July and August), meanwhile the bimodal maxima are concentrated on Spring (March) and Autumn (October or November).
