| Zusammenfassung |
| We compare the physical mechanisms involved in the generation and decay of ENSO
events in a control (present day conditions) and Scenario (Is92a,
IPCC 1996) simulations performed
with the coupled ocean-atmosphere GCM ECHAM4-OPYC3.
A clustering technique which objectively discriminates common features in the evolution
of the Tropical Pacific Heat Content anomalies leading to the peak of ENSO events allows
us to group into a few classes the ENSO events occurring in 240 years of data in the
control and scenario runs. In both simulations, the composites of the groups show differences
in the generation and development of ENSO. We present the changes in the statistics of the
groups and explore the possible mechanisms involved. |
