| description | <p>The frequency of extreme events has changed, having a
direct impact on human lives. Regional climate models help us to predict
these regional climate changes. This work presents an atmosphere–ocean
coupled regional climate system model (RCSM; with the atmospheric component
COSMO-CLM and the ocean component NEMO) over the European domain, including
three marginal seas: the Mediterranean, North, and Baltic Sea. To
test the model, we evaluate a simulation of more than 100 years
(1900–2009) with a spatial grid resolution of about 25 km. The simulation was
nested into a coupled global simulation with the model MPI-ESM in a
low-resolution configuration, whose ocean temperature and salinity were
nudged to the ocean–ice component of the MPI-ESM forced with the NOAA
20th Century Reanalysis (20CR). The evaluation shows the robustness of
the RCSM and discusses the added value by the coupled marginal seas over an
atmosphere-only simulation. The coupled system is stable for the complete
20th century and provides a better representation of extreme
temperatures compared to the atmosphere-only model. The produced long-term
dataset will help us to better understand the processes leading to
meteorological and climate extremes.</p> |
