Received: 27 Sep 2010 – Published in Clim. Past Discuss.: 08 Oct 2010Abstract. A high-resolution (30 km) regional paleoclimate simulation of the last
millennium over the Iberian Peninsula (IP) is presented. The simulation was
performed with a climate version of the mesoscale model MM5 driven by the
global model ECHO-G. Both models were driven by the same reconstructions of
several external forcing factors. The high spatial resolution of the regional
model allows climatologists to realistically simulate many aspects of the climate in the IP,
as compared to an observational data set in the reference period 1961–1990.
Although the spatial-averaged values developed by the regional model are
tightly driven by the boundary conditions, it is capable to develop a
different realisation of the past climate at regional scales, especially in
the high-frequency domain and for precipitation. This has to be considered
when comparing the results of climate simulations versus proxy
reconstructions. A preliminary comparison of the simulation results with
reconstructions of temperature and precipitation over the IP shows good
agreement in the warming trends in the last century of the simulation,
although there are large disagreements in key periods such as the
precipitation anomalies in the Maunder Minimum.
