Zusammenfassung |
In this manuscript we describe the experimental procedure employed
at the Alfred Wegener Institute in Germany in the preparation of the simulations
for the Pliocene Model Intercomparison Project (PlioMIP). We present a description
of the utilized Community Earth System Models (COSMOS, version: COSMOS-landveg r2413, 2009) and document the procedures
that we applied to transfer the Pliocene Research, Interpretation and Synoptic
Mapping (PRISM) Project mid-Pliocene reconstruction into model forcing fields. The model
setup and spin-up procedure are described for both the paleo- and preindustrial (PI)
time slices of PlioMIP experiments 1 and 2, and general results that depict the
performance of our model setup for mid-Pliocene conditions are presented. The
mid-Pliocene, as simulated with our COSMOS setup and PRISM boundary
conditions, is both warmer and wetter in the global mean than the PI. The globally averaged annual mean surface air
temperature in the mid-Pliocene standalone atmosphere (fully coupled atmosphere-ocean)
simulation is 17.35 °C (17.82 °C), which implies
a warming of 2.23 °C (3.40 °C) relative to the
respective PI control simulation. |
