Doctoral candidate (f/m/d)

Leibniz-Zentrum für Marine Tropenforschung GmbH (ZMT), Bremen

The Leibniz Centre for Tropical Marine Research (www.leibniz-zmt.de) in Bremen is a member of the Leibniz Association, which is supported by the German Federal and State Governments. Through its research, ZMT contributes to developing science-based strategies for sustainable use of tropical coastal systems.

Doctoral candidate (f/m/d)

ERC-funded PhD position on tropical convective self-organization 

(Reference number: 183)

The position and scope. This is a collaborative PhD position between the Leibniz Centre for Tropical Marine Research (ZMT), Bremen, Germany, and the Niels Bohr Institute (NBI, www.nbi.ku.dk/english/), University of Copenhagen, Denmark. We are seeking a motivated PhD student who will study the self-organization of convective clouds over the tropical oceans and continents. The position is funded through the ERC project “Cloud-cloud interaction in convective precipitation” (INTERACTION). Self-organization of convective clouds has been implicated in the emergence of mesoscale convective systems, the Madden-Julian Oscillation and tropical cyclone formation. The candidate will join a team of several other PhD students and postdocs.

Important - and so-far incompletely understood - organizing mechanisms in convection are, on the one hand, the interactions among cold pools (boundary layer), and, on the other, those between clouds and radiation within the free troposphere. Within this PhD project, a theoretical methodology will be developed, that allows these interactions to be encapsulated into a simplified modeling framework.

We will make use of numerical experiments from high-resolution large-eddy and cloud-resolving simulations, which are already carried out within the team. Together with the team, new numerical experiments will be designed and implemented. We will further be exploring observational data, e.g., from satellite or ground-based stations, and there will be close exchange of findings between the observational and modeling projects.

International scope. The student will be based within the Complexity and Climate group at ZMT, graduate course work will however be carried out at the NBI, where the candidate will spend part of their PhD to collaborate with the Atmospheric Complexity Group (atmospheric-complexity.nbi.ku.dk). The PhD degree will be awarded by the NBI. Further, the PhD student will be able to collaborate within the transregio project TRR181 (Energy Transfers in Atmosphere and Ocean: https://www.trr-energytransfers.de/). 

Requirements. Candidates with a background in physics, mathematics, meteorology/atmospheric science or computational fluid dynamics are especially encouraged to apply. Candidates should have completed the equivalent of a two-year M.Sc. degree, or be close to its completion. Working experience with an efficient programing language (e.g. fortran, python, c/c++, or similar) is expected. Curiosity and creativity for building conceptual, simplified mathematical models is crucial. Some familiarity with atmospheric dynamics and thermodynamics, or ocean-atmosphere interaction will be beneficial, but is not critical. Enthusiasm to both work within a team and alone are expected.

Details of the position:

The candidate will be on a part-time position (66,6%) on a 36-month contract; starting in February 2021, or as soon as possible thereafter. Salary will be paid according to the German TV-L EG 13.

We offer:

  • An exciting working environment in an interdisciplinary and internationally oriented institute
  • Possibilities to build and extend an international professional network and participate in a research field of high public and scientific interest
  • A family-friendly working environment
