Tur­bu­lence: Decades-old the­ory gets a major remake

Turbulence plays an essential role in weather and climate, and correctly representing its effects in numerical models is crucial for accurate weather forecasts and climate projections. However, the theory describing the effect of turbulence has not changed since its conception in 1950s, despite the fact that it is not representative for the majority of the Earth’s land surface, especially over mountains and polar regions. The Innsbruck meteorologist Ivana Stiperski has now extended the turbulence theory to complex atmospheric conditions. The researcher thus paves the way for the first generalized turbulence theory over complex terrain.

COVID-19: The current semester

Even though Corona will remain and we will all have to live with it in the long run, we are currently in a very good situation - from the point of view of society as a whole as well as within the university. Therefore, all currently valid regulations at the University of Innsbruck regarding COVID-19 will be lifted with immediate effect. The Rector's team is very concerned about the health of all university employees, which is why the situation around COVID-19 will be monitored in the future in order to be able to take necessary steps if necessary.

Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental assumption for air quality forecasting has to be reinterpreted for urban areas. Measurements by an international team led by atmospheric scientist Thomas Karl of the University of Innsbruck also show that direct nitrogen dioxide emissions are overestimated.
