PhD student natural variability in climate models
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.
PhD student "natural variability in climate models" (m/f/d)
Background
Natural climate variability on decadal to centennial time scales is currently not well constrained and existing climate models appear to be too stable in magnitude as well as in the response of climate variability to mean climate changes.This PhD project will use unique modelling capabilities at AWI – exploiting a next-generation climate model (AWI-CM) that is highly scalable and allows to increase resolution in dynamically active regions – to investigate why current climate models are so stable and how this can be overcome. To this end, different model configurations of the AWI-CM will be used to explore the role of increased horizontal resolution and changes to some critical parametrisations.
Tasks
You will- Develop metrics and diagnostics used for model assessment.
- Analyse simulated natural variability in existing CMIP6 simulations (baseline).
- Carry out and analyse dedicated experiments with high-resolution model configurations.
- Carry out and analyse model experiments studying the sensitivity to model parametrisations and forcing.
- Contribute to closing the current gap between simulated vs. observed natural climate variability.
- Work closely with two other PhD students approaching this challenge from the terrestrial data and the paleo climate analysis side.
Requirements
- Strong analytical skills.
- Proficiency in a programming language.
- A degree (Master, Diploma) in climate sciences, physics, environmental sciences or a related field.
- Excellent English language skills, both written and spoken.
- Interest in working with climate models.
- Previous experience with climate research, including modelling, is an advantage.
- Experience in data analysis, Fortran and Python is a benefit.
