The research group Theory of Atmospheric Dynamics and Climate at the Institute of Atmospheric and Environmental Sciences of the Goethe University in the city of Frankfurt ( invites applications for a 

Research Assistant (m/f/d)
Postdoctoral Scientist
(E13 TV-G-U)

The position is limited until 30.06.2025 und is funded within the Transregional Collaborative Research Centre 301 ( “TPChange – The Tropopause Region in a Changing Atmosphere” by the German Research Foundation (DFG, Deutsche Forschungsgemeinschaft). The salary grade is based on the job characteristics of the collective agreement (TV-G-U) applicable to the Goethe University.

Within TPChange we aim to improve the understanding of relevant multiscale processes in the tropopause region and to specify their impact on composition, dynamics and ultimately on future climate and climate variability. The postdoctoral scientist will work in project B07:

“Impact of cirrus clouds on tropopause structure”

Project leaders: Prof. Ulrich Achatz (Goethe University Frankfurt) in collaboration with Prof. Peter Spichtinger (University Mainz).

Cirrus clouds frequently occur in the tropopause region. They have a crucial impact on the thermodynamic structure of the tropopause region by diabatic processes (e.g. latent heat and radiation); temperature gradients and water vapour distributions are actively changed by these clouds. On the other hand, cirrus clouds are crucially affected by local dynamics, originating from gravity waves as well as dynamic and convective instabilities. The main goal of the project is to investigate the interaction of cirrus clouds and local dynamical processes, and their impact on the tropopause region. Using theoretical investigations with sophisticated mathematical methods as well as numerical modelling, we will investigate these interactions in order to develop new consistent parameterisations for the use in coarse grid models, finally.

The position to be filled will address the interaction of gravity waves and ice clouds in the tropopause region. It will also work at the representation of this interaction in climate models, by a corresponding extension of the new gravity-wave model MS-GWaM, recently implemented and validated in the weather and climate code ICON.

Information on the research group where the position will be located can be found at Its focus is on scale interactions in atmospheric dynamics, applied e.g. to large-scale low-frequency variability or gravity-wave dynamics. Middle-atmosphere dynamics is another field of work. Methods employed are e.g. multi-scale asymptotics, stochastics, and numerical simulations. Inquiries should be addressed to Prof. Dr. Ulrich Achatz (

TPChange offers a comprehensive and structured training for early career researchers. In addition to self-organized activities such as workshops, trainings and a guest program, the successful candidate will have the opportunity, if desired, to pursue international research visits. The consortium conducts an ambitious program to gradually enhance gender equality on all career levels.

Applicants should have a very good PhD in meteorology, physics, applied mathematics, fluid dynamics, or a related field. Expected is a strong background in theory and/or modeling.

The university is committed to equal rights for women and men and therefore strongly encourages women to apply. Severely disabled persons are given priority in the case of equal qualifications.

Applications and deadline
Please send applications with reference to the code B07_PD_GUF as one single pdf file to, including (i) a letter of motivation, (ii) a CV, (iii) copies of all relevant certificates, and at least two contacts for reference letters by 15.5.2022. For further information, please contact

We look forward to your application!
