Experiment
Summary
The purpose of the experiment was to evaluate the long term atmospheric response to pre-
scribed SST anomoaly patterns over the period 1979-1992 by carrying out a series of simula-
tions with the same atmospheric model but starting from different atmospheric initial states

The ECHAM3 model was essentially finalized in late 1992 and has since then been extensively
used in different climate experiments. Together with a large number of other modelling groups,
the ECHAM3 model has also taken part in the so called AMIP investigations ("1992: AMIP:The
atmospheric model intercomparison project, Bull. Am. Met. Soc., 73 (12), 1962-1970," Gates, 1992).
The model has mainly been used at low and medium horizontal resolutions, T21 and T42, in
addition shorter integrations of 5 years duration have been done at a T106 resolution.

Five different integrations were than carried out all using different atmospheric initial states.
The initial data were all obtained from control runs with climatological SST starting several
month beforehand. The original archive was generated with a time resolution of 12 hours; the
majority of the investigations in this study has been using a special archive of seasonally averaged data.

The central objective of this study is to explore the impact and importance of SST anomalies of
the low frequency circulation of the atmosphere."(Climate predictability experiments with a
general circulation model, Max-Planck_Report No. 145, Bengtsson, Arpe, Roeckner, Schulzweida).


This is the control run which produces the initial states for the five experiments:
ECHAM3_T42_22056HMBG, ECHAM3_T42_22062LLNL, ECHAM3_T42_23101AMIP, ECHAM3_T42_23102AMIP,
ECHAM3_T42_23103AMIP.
