Abstract

This work presents a dynamical technique of climate downscaling to generate projections for the 21st Century in Catalonia, based on the outputs of the atmosphere-ocean global coupled model ECHAM5/MPI-OM. This technique consists in long integrations (5 years) with the MM5 mesoscalar model through three one-way nested domains of 135, 45 and 15 km of horizontal resolution and 23 vertical levels. Two possible emission scenarios of the Special Report on Emissions Scenarios are used for the generation of downscaled projections: a severe one (A2) and a moderate one (B1).

Key words: Catalonia, climate change, climate downscaling, MM5, projections

Abstract

The meteorological model WRF-ARW (Weather Research and Forecasting - Advanced Research WRF) is a new generation model that has a worldwide growing community of users. In the framework of a project that studies the feasibility of implementing it operationally at the Meteorological Service of Catalonia, a verification of the forecasts produced by the model in several cases of precipitation observed over Catalonia has been carried out.

Key words: Catalonia, convection, mesoscale, microphysics, WRF
