Objective
To improve the understanding of natural climate variability on timescales of decades and centuries, and to prepare a multi-millenia numerical experiment with an improved fully coupled ocean-atmosphere-ice model.
The output from the 1250 year MPI climate simulation will be examined in order to identify and eventually
understand the internal mechanisms of the climate system which are responsible for the formation of low
frequency anomalies. An better degree of realism of the model data will be established by comparing with
observed and analysed data.
This analysis will include the utilisation of dynamical theory and a number of statistical techniques, such as
EOFs, POPs and multichannel singular spectrum analysis, in order to identify principal modal structures and
their dynamics. Additional numerical experiments with Ocean and atmosphere GCMs will be used to study
particular aspects of the atmosphere ocean couplings.
The low frequency variability created in the 1250 year experiment will be compared with proxy data from tree
rings and ice cores and to historical atmospheric and oceanic data. Nonlinear analysis techniques will be used
to describe the attractor, principal weather regimes and principal clusters in the modelled climate system. The
models systematic errors on time scales of large anomalies will be diagnosed; special emphasis will be placed
on the variability relating to sea-ice, the maintenance of recurrent anomalies and teleconnection patterns.
For the preparation of a future multi-millenia numerical experiment the dynamical, diagnostic, numerical and
logistic requirements of a coupled ocean-atmosphere model to allow for realistic simulations of climate
variability on time scales of decades to centuries. A number of specific issues will be investigated: The vertical
resolution in the atmospheric part, the tendency errors related to specific parametrisations, such as horizontal
diffusion, gravity wave drag, atmosphere sea-ice interactions, and the vertical mixing in the O-GCM. Specific
attention will be paid to the flux-correction technique.
The link between ENSO dynamics and longer term fluctuations will be studied in a number of numerical
experiments (AGCM with observed SSTs), and the need for explicit resolving ENSO in the ocean model will
be evaluated.
A critical assessment of the data requirements for analyses will be done, and a number of statistical methods
will be evaluated in order to select those most suited for the identification of slow variations, teleconnections
etc.
On this basis a design proposal will be formulated for the final configuration of the MILLENIA coupled model.
