Acero et al. (2010) Peaks-over-Threshold Study of Trends in Extreme Rainfall over the Iberian Peninsula
This study evaluates two Met Office regional climate models (RCMs) at 12-kilometer (parameterized convection) and 1.5-kilometer (explicit convection) resolutions for simulating multihourly precipitation extremes over the southern United Kingdom. It concludes that the 1.5-kilometer RCM provides a more realistic representation of summer subdaily extreme events, despite a positive bias, while the 12-kilometer RCM suffers from unrealistic "gridpoint storms" leading to overly intense long-return-period extremes.

Sinoga et al. (2010) Precipitation dynamics in southern Spain: trends and cycles
This study analyzed the temporal variability of precipitation in southern Spain from 1960 to 2006 to detect trends and cycles. It found significant spatial differences, with negative precipitation trends for east coast and inland stations, increasing trends for west coast stations, and a general seasonal decrease (especially in winter, autumn, and spring) across most regions.
