| Zusammenfassung |
| FAMOUS is an ocean-atmosphere general circulation model of low resolution,
capable of simulating approximately 120 years of model climate per wallclock
day using current high performance computing facilities. It uses most of the
same code as HadCM3, a widely used climate model of higher resolution and
computational cost, and has been tuned to reproduce the same climate
reasonably well. FAMOUS is useful for climate simulations where the
computational cost makes the application of HadCM3 unfeasible, either because
of the length of simulation or the size of the ensemble desired. We document
a number of scientific and technical improvements to the original version of
FAMOUS. These improvements include changes to the parameterisations of ozone
and sea-ice which alleviate a significant cold bias from high northern
latitudes and the upper troposphere, and the elimination of volume-averaged
drifts in ocean tracers. A simple model of the marine carbon cycle has also
been included. A particular goal of FAMOUS is to conduct millennial-scale
paleoclimate simulations of Quaternary ice ages; to this end, a number of
useful changes to the model infrastructure have been made. |
