| Zusammenfassung |
| We present and analyse a high-resolution regional climate palaeosimulation
encompassing the European region for the period 1500–1990. We use the
regional model MM5 driven at the boundaries by the global model ECHO-G. Both
models are forced by reconstructions of three external factors: greenhouse
gas concentrations, total solar irradiance and volcanic activity. The
simulation skill is assessed in a recent period by comparing the model
results with the Climate Research Unit (CRU) database. The results show that
although the regional model is tightly driven by the boundary conditions, it
is able to improve the reliability of the simulations, narrowing the
differences to the observations, especially in areas of complex topography.
Additionally, the evolution of the spatial distributions of temperature and
precipitation through the last five centuries is analysed, showing that the
mean values of temperature reflects the influence of the external forcings.
However, contrary to the results obtained under climate change scenario
conditions, higher-order momenta of seasonal temperature and precipitation
are hardly affected by changes in the external forcings. |
