PhD position: Anthropogenic effects on the atmosphere-ocean circulation – Deadline 31 May 2023

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation under public law jointly financed by the Federal Republic of Germany (90%) and the State of Schleswig-Holstein (10%). It is one of the internationally leading institutions in the field of marine research.

Through our research and our commitment to the transfer of knowledge and technology, we contribute significantly to the preservation of the function and protection of the ocean for future generations.

The research unit Marine Meteorology of the research division Ocean Circulation and Climate Dynamics is offering a position as PhD student Anthropogenic effects on the atmosphere-ocean circulation, starting as soon as possible. The position offers the possibility to attain a doctoral degree in natural sciences.

We are looking for an enthusiastic student for fundamental research on the influences of anthropogenic changes in the atmospheric composition on the circulation of the atmosphere and in the ocean. The aim is to quantify and qualitatively understand contributions from different changes in atmospheric composition on the circulation response. To that end, existing CMIP6 model data are used and own simulations with systematic changes in the atmospheric composition will be used. A focus of the work is the systematic investigation of the influence of anthropogenic aerosols from different regions of the world on the circulation. The project will be led by the leader of the research unit.

The research unit Marine Meteorology works on quantifying and better understanding the relative importance of atmospheric and oceanic processes in controlling climate variability and change on a large range of timescales: from hourly, through decadal, to centennial timescales.  The research unit offers a young and dynamic team, an internationally active working environment, the possibility to be part of academic teaching, support on technical questions and arrangements for a flexible work-live balance. Kiel and the surrounding region have with the proximity to the Baltic Sea many offers for recreation and leisure, plus a cultural scene shaped by the university and water sports.

Job Description

  • Fundamental research on interactions of atmospheric composition and atmosphere-ocean circulation
  • Scientific analysis of big data sets from models with climate simulations, including the application of automatic detection algorithms for dynamic processes which may contain methods of machine learning for pattern detection
  • Graphical display of the results
  • Scientific publications of the results as journal articles
  • Presentations at international conferences of the field
  • Performing experiments with complex models on high-performance computers
  • Participation in training courses
  • Qualification for a PhD


  • Very good master degree in Physics, Meteorology, Climate Science, Informatics, or similar
  • An excellent physical understanding of weather and climate, knowledge about atmospheric dynamics, climate change, climate modelling, and/or aerosols and their effects desirable
  • Very good programming skills (python, shell scripts, FORTRAN and/or comparable) programming experiences desirable
  • Interest in using methods of machine learning and high performance-computing, knowledge and first experience desirable
  • Very good English skills, German is a plus but not mandatory
  • Good presentation skills and the willingness for inter-/national travel
  • Ability to work in teams and alone, interest in developing skills

Our offer

At a workplace, directly on the Kiel Fjord with many leisure and recreational opportunities, we offer you:

  • Support services for professional and personal life situations
  • An exciting work environment with the opportunity to provide important impetus for the development of sustainable solutions
  • Work in the field of marine and climate research, a forward-looking area with social significance
  • 30 + additional time off at Christmas and New Year’s Eve
  • Company pension plan and capital-forming benefits

The fixed-term position is available for a period for three years.

The salary depends on qualification and could be up to the class 13 TVöD-Bund of the German tariff for public employees. This is a part-time position according to 75 % of a full-time equivalent. The position cannot be split. Flexible working time models are generally possible. The fixed-term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).
