Prof. Ivana Siperski
Ivana Stiperski was born in 1980 in Zagreb, Croatia. She studied Physics/Geophysics with the focus on the physics of atmosphere and ocean, at the University of Zagreb, where she completed her doctorate in 2010. One year later, she moved to the University of Innsbruck and worked in the group of Mathias Rotach on mountainous boundary layers.

Abstract: In atmospheric sciences, turbulence plays a crucial role as the main mechanism of exchange and transport of energy, momentum and mass between the earth’s surface and the overlying atmosphere, influencing all atmospheric phenomena from smallest scale processes that govern minimum nighttime temperatures (important for road safety and agriculture) to largest scales such as climate. Accurate numerical modelling of turbulence, however, presents a special set of challenges, due to the non-linear and multiscale nature of turbulence. Different numerical approaches are therefore employed, however, all with their own advantages and drawbacks. Modelling turbulence over topography, adds additional challenges associated with non-flat boundaries and the challenge of keeping the flow turbulent within the domain. In this talk I will highlight the different numerical approaches and their challenges, and potential solutions for simulating highly accurate turbulent flow over topography.
Drinks after the talk for free!
