The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics, thus allowing multidisciplinary approaches to scientific goals.

Postdoc - Storyline scenarios of extreme events with km-scale climate models using spectral nudging (m/f/d)


Background The Climate Dynamics section at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany, invites applications for a postdoc position in which spectral nudging will be employed in novel km-scale climate models for the evaluation of model fidelity and for the development of storyline scenarios of recent extreme events (e.g., heat waves and flooding). You will work at the interface of innovative science and technology with leading European climate modelers, computing scientists and software engineers on developing and applying digital twins of the climate system in support of adaptation to anthropogenic climate change.


You will be part of a team responsible for the development and application of spectral nudging capabilities in support of model evaluation and storyline scenario generation. More specifically, you will be in charge of developing storyline capabilities for km-scale atmosphere-only setups (technology for medium-resolution coupled setups is available) and use this configuration to explore how recent extreme events such as the flooding events in Europe in July 2021 might have unfolded in pre-industrial times (storyline attribution) and could unfold in +1.5K, +2K, +3K and +4K warmer worlds (storyline scenarios). Furthermore, you will carry out and analyse spectral nudging experiments with the coupled version of the km-scale system for the period 2017-today to provide novel insights into the origin of possible model short-comings.


A PhD in one or more of the following fields is required: Atmospheric physics, oceanography, climate sciences, physics, mathematics or related. Furthermore, a good understanding of climate dynamics and hands-on experience with climate models on HPC systems are expected. Demonstrated skill/proficiency in at least one programming language (e.g., FORTRAN and/or Python) and fluency in English are further requirements. Moreover, a track record of publishing in the peer-reviewed literature and the ability to communicate results are both distinct advantages. Given that the success of this project hinges on effective collaboration between partners, strong communication skills and the ability to work in teams are both a necessity.

Having experience in some of the following fields would be a distinct advantage:

  • Model error diagnosis
  • Model development and/or tuning
  • Effective communication of results
  • Handling and analysis of complex data formats (netCDF, zarr, CDO)
