AB: The aim of this work is the detection of trends in the tail of the daily precipitation distribution, described in the framework of the Extreme Value Analysis, for the period 1960-2000 over the UK and to study the dependency on relevant physical quantities and circulation indices. The distributions are those obtained from observed precipitation, aggregated over the RCM ENSEMBLES UK grid-boxes (at 25km horizontal resolution), and simulated by the ENSEMBLES RT3 regional climate models driven by ERA-40 reanalysis boundary conditions over the same area. Trends from the observations and an assessment of the ability of the models to reproduce these trends and the relationship with other covariates will be presented at the conference.
