The climate of Sierra Nevada affects many relevant aspects for the living systems that inhabit it as well as the water resources of a region with semi-arid characteristics. Climate change in the Sierra Nevada can be especially exacerbated by its condition of mountainous region and its location in the Mediterranean area, which makes it a double climate change hotspot. Monitoring and studyng its present and future climate are crucial to define adaptation strategies to climate change and the use of very high-resolution regional models becomes a useful tool in this area of complex topography.

In this work we evaluate climate simulations at a resolution of 1 km using the Weather Research and Forecasting (WRF) model as a convection permitting model and we analyze the added value of these simulations with respect to another with a resolution of 5 km for the Sierra Nevada area. The simulations cover the period 2001-2020 and the analysis focuses on the study of precipitation. The simulated precipitation is compared with observational data mainly from the Climanevada database (https://climanevada.obsnev.es/).

In addition to analyzing the mean precipitation values and some extreme indices, the evaluation is also focused on the comparison of the simulated data for some extreme events in order to analyze both the increasing improvement in the spatial and temporal resolutions.

Keywords: Sierra Nevada, precipitation, WRF, convection permitting model, added value.
