DESCRIPTION

Energetic inconsistencies in present climate models feature errors of the same magnitude as the energy imbalance of Earth’s climate system due to anthropogenic greenhouse gas emissions. This leads to biases that limit the models’ ability to project climate relevant physical processes. The collaborative research centre TRR 181 “Energy Transfers in Atmosphere and Ocean” aims to address these shortcomings by deepening the physical understanding of energy transfers between the main dynamical regimes, i.e., geostrophic motions, gravity waves, and turbulence.
The successful candidate will particularly contribute to the synthesis project S3 on the analysis of the impact of parameterisations and numerical schemes developed within TRR 181. The successful candidate will evaluate the project models ICON and IFS-FESOM in comparison to Earth observations and other models participating in the Coupled Model Intercomparison Project (CMIP), with a focus on assessing improvements in the newly developed parametrizations and numerical schemes of the project. Historical and future simulations in addition to the Diagnostic, Evaluation and Characterization of Klima (DECK) experiments will be performed and analysed. The successful candidate will become part of the development consortium of the Earth System Model Evaluation Tool (ESMValTool, https://esmvaltool.org/).

ADDITIONAL (DESIRED) SKILLS:

• Experience in Earth system modelling, parameterisation and climate science
• Experience in using high performance computer systems
  Allgemeine Hinweise
  Open to unconventional approaches in research and teaching, the University of Bremen has retained its character as a place of short distances for people and ideas since its founding in 1971. With a broad range of subjects, we combine exceptional performance and innovative potential. As an ambitious research university, we stand for research-based learning approaches and a pronounced interdisciplinary orientation. We actively pursue international scientific cooperation in a spirit of global partnership.
  Today, around 23,000 people learn, teach, research and work on our international campus. In research and teaching, administration and operations, we are firmly committed to the goals of sustainability, climate justice and climate neutrality. Our Bremen spirit is expressed in the courage to dare new things, in supportive cooperation, in respect and appreciation for each other. With our study and research profile and as part of the European YUFE network, we assume social responsibility in the region, in Europe and in the world.
  The university is family-friendly, diverse and sees itself as an international university. We therefore welcome all applicants regardless of gender, nationality, ethnic and social origin, religion/belief, disability, age, sexual orientation and identity.
  As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply.
  Disabled applicants will be given priority if their professional and personal qualifications are essentially the same.
