RT info:eu-repo/semantics/article T1 The Role of Weather Types in Assessing the Rainfall Key Factors for Erosion in Two Different Climatic Regions A1 Fernández Raga, María A1 Fraile Laiz, Roberto A1 Palencia Coto, María Covadonga A1 Marcos Porras, Elena María A1 Castañón García, Ana María A1 Castro Izquierdo, Amaya A2 Explotacion de Minas K1 Meteorología K1 Clima K1 Lluvia K1 Energía mecánica K1 León K1 Aveiro K1 2502 Climatología K1 2509 Meteorología AB This paper compares two different geographical sites, Aveiro and León, from different climatic regions, oceanic and continental, but which share the same type of weather (according to Lamb’s classification). The analysis was carried out over one year, and has revealed that rainfall in Aveiro is heavier and more abundant, with a higher number of raindrops and a longer duration of rain events (on average, 10 min longer than in Leon). Mean raindrop size is 0.45 mm in Aveiro and slightly smaller (0.37 mm) in Leon; in addition, the kinetic energy and linear momentum values in Aveiro are three times higher than those in Leon. A comparison of raindrop size distributions by weather type has shown that for both locations westerly weather presented a higher probability of rainfall, and the gamma distribution parameters for each weather type were independent of the study zone. When the analysis is done for the characteristics of rain related with erosion, the westerly cyclonic weather types (cyclonic west (CW) and cyclonic south-westerly (CSW)) are among the most energetic ones in both locations. However, comparing their five weather types with higher kinetic energy, in Aveiro a westerly component implies higher kinetic energy, while in Leon a southerly component involves more energy in the rain.
