| Zusammenfassung |
| The mid-Pliocene warm period ~3.264 to 3.025 Ma) is a
potential analogue for future climate under global warming. In this study,
we use an atmospheric general circulation model (AGCM) called CAM3.1 to
simulate the mid-Pliocene climate with the PRISM3D boundary conditions. The
simulations show that the global annual mean surface air temperature (SAT)
increases by 2.0 °C in the mid-Pliocene compared with the
pre-industrial temperature. The greatest warming occurs at high latitudes of
both hemispheres, with little change in SAT at low latitudes. The
equator-to-pole SAT gradient is reduced in the mid-Pliocene simulation. The
annual mean precipitation is enhanced by 3.6% of the pre-industrial
value. However, the changes in precipitation are greater at low latitudes
than at high latitudes. |
