Description

Leader of the group Multiscale Dynamics: Ute Ebert.

Nature and technology are full of dynamics, often involving multiple scales in length, time and energy. To model these processes, we combine scientific computing with model reduction and machine learning, with particular focus on plasma dynamics in lightning and space weather, and in high voltage and plasma technology.

Our research addresses questions in nature such as start and propagation of lightning strokes, terrestrial gamma-ray flashes and space weather, and closely related technological problems such as switch gear for long-distance electricity nets, air purification and disinfection with corona reactors, and protection of satellites and electricity nets from space weather.

Within national and European projects, we collaborate with colleagues in applied plasma physics, electrical and mechanical engineering, atmospheric electricity, and cosmic particle and space science, and with non-academic partners such as ABB, DNV-GL, ESA-ESTEC and NASA.

Exploding stars help to understand thunderclouds on Earth

Exploding stars help to understand thunderclouds on Earth

How is lightning initiated in thunderclouds? This is difficult to answer – how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. This surprising finding will be published in Physical Review Letters on April 24nd.

Creation of antimatter from lightning simulated for the first time

In severe thunderstorms electric fields can become so high, that high energy radiation – such as X-rays and gamma rays - can be generated. Even antimatter can be formed. The highly complex interactions between high electric fields and particles in thunderstorms were not well modelled yet. Christoph Köhn, PhD student from research centre Centrum Wiskunde & Informatica (CWI) in Amsterdam, modelled and simulated these processes in a new way.
