Schemm, Sebastian

Part-time PostDoc in the Atmospheric Dynamics group, interested in the development of mid-latitude cyclones and the atmospheric circulation.

An animation of one of my idealized cyclone simulations can be found in the Section: Research Highlights of Atmospheric Dynamics Group. The attached picture shows one idealised cyclone and trajectories of the warm conveyor belt: WCB.

I am co-founder of the recently established association of the scientific staff at our department and elected member of the departements conference. Before I served as a PhD spokes person to the institutes board.

General Research Interests

• Dynamics of mid-latitude cyclones and weather systems (extreme and not so extreme events).
• General circulation of the atmosphere (e.g. climate dynamics).
• Storm track dynamics and jet streams.

Specific Research Interests

• Moist baroclinic instability and idealized simulations.
• Conceptual cyclone development (e.g. the conveyor belt model).
• Rossby waves and breaking events.
• Diabatic modifications of cyclones (especially from a potential vorticity perspective).

Interdisciplinary Research Interests

• Sustainable Research and Development and society impacts.
• Epistemology (especially Descartes and Spinoza).
• Maschine learning.
