Ocean Circulation and Climate Dynamics

Physics of the atmosphere

July, 2017

The understanding and quantification of natural climate variability in the Earth's system from seasonal to multidecadal time scales is essential for more reliable future climate predictions. Together with volcanic activity, solar variability could be an important external source of natural climate variations, superimposed on the human-induced warming since the late twentieth century. Modeling the complex interactions between dynamical, physical and chemical processes in the atmosphere from the middle atmosphere (stratosphere and mesosphere) to the Earth’s surface and its interaction with the ocean circulation is necessary to understand the underlying physical mechanisms. Observations on the other hand are an important component for monitoring atmosphere-ocean interactions as well as improving and validating climate models.



Research Areas

  • Stratosphere-troposphere-ocean modeling with special focus on chemistry-climate modeling

  • Role of the middle atmosphere for (natural) climate variability

  • Mechanisms for sun-climate interactions

  • Decadal climate variability and predictability

  • Processes in the UTLS (Upper Troposphere Lower Stratosphere)

  • Development of and contribution to international model intercomparison studies of climate variability and climate change

  • Air-sea interactions, in particular turbulent heat transfer and precipitation measurements


  • WCRP-SPARC SOLARIS-HEPPA Working Group on Solar Activity 

  • BMBF ROMIC-SOLIC (Role Of the MIddle atmosphere in Climate: Quantification of Uncertainties of Solar Induced Climate variability)
