Zusammenfassung |
The global distribution of late Pliocene soils and lakes has been
reconstructed using a synthesis of geological data. These reconstructions
are then used as boundary conditions for the Hadley Centre General
Circulation Model (HadCM3) and the BIOME4 mechanistic vegetation model. By
combining our novel soil and lake reconstructions with a fully coupled
climate model we are able to explore the feedbacks of soils and lakes on the
climate of the late Pliocene. Our experiments reveal regionally confined
changes of local climate and vegetation in response to the new boundary
conditions. The addition of late Pliocene soils has the largest influence on
surface air temperatures, with notable increases in Australia, the southern part
of northern Africa and in Asia. The inclusion of late Pliocene lakes increases
precipitation in central Africa and at the locations of lakes in the
Northern Hemisphere. When combined, the feedbacks on climate from late
Pliocene lakes and soils improve the data to model fit in western North
America and the southern part of northern Africa. |
