The Tropical Atlantic SST bias in the Kiel Climate Model

Until today, the Tropical Atlantic Ocean is a region which is difficult to represent in numerical models. Most of the current coupled general circulation models (CGCM) show a strong warm bias in the eastern Tropical Atlantic and are unable to reproduce the observed variability especially directly along...

Annual to interannual equatorial Atlantic variability : mechanisms and...

In this thesis, I investigate the annual to interannual variability in the equatorial Atlantic and its impacts on other tropical oceans. There are three parts to this work. The first part (chapter 2) is to understand the seasonal cycle of ocean dynamics, which has been published in 2009. The second part...

North Atlantic multidecadal to centennial variability in a model and a...

Variability on decadal and longer timescales is of great interest in climate research due to it’s socio-economic impacts, potential for predictability and masking of anthroprogenic global warming. Observational evidence of multidecadal variability in the North Atlantic exists in the sea surface temperature...

Interannual variability in the southeastern tropical Atlantic Ocean : Benguela...

Interannual sea surface temperature (SST) variations of the tropical oceans are of particular interest due to their close relation to rainfall variability over adjacent land regions. For the eastern tropical Atlantic two recurring El Nino-like phenomena with high interannual SST anomalies have been described,...

The Role of Ocean-Atmosphere Interaction over the Gulf Stream SST-front...

This work deals with various aspects of the atmospheric response to mid-latitude SST fronts, in particular in the Gulf Stream region. It consists of three parts: In the first part the effect of enhanced model resolution on the correct representation of the processes in the frontal region is discussed,...
