Laboratory of Atmospheric Physics
Our main research topics are global and regional climate change. We also work on applications for short range weather forecasting.
- We study the complex physical process of climate change. Anthropogenic greenhouse gases warm the Earth’s climate. But the cooling effect of tiny solid and liquid pollution particles, called atmospheric aerosols, compensates part of this warming. The impact of aerosol particles on clouds is the most uncertain component of anthropogenic climate forcing. We study the aerosol impact on clouds via remote sensing methods and climate modelling.
- In the Baltic Sea region, the warming of the Earth’s atmosphere has been more rapid compared to the global average. The changes in atmospheric circulation are one important cause for this. We study the relationships between the changes in atmospheric circulation in the Baltic Sea region and extreme precipitation, storm surges and salinity dynamics of the Baltic Sea. We also study the long term changes in atmospheric transparency. For this research we apply various computational methods and machine learning.
- We improve the methods for short range weather forecasting. An important application in this work is remote sensing of precipitation with weather radars. We also work with the models of numerical weather prediction and simulate atmospheric transport of air pollution. We have been working on improving the weather prediction models used in the Estonian Weather Service. For this research we use weather radars, machine learning and numerical models of atmospheric dynamics.
Research computations are carried out at the High Performance Computing Centre of Tartu University.
We teach atmospheric and environmental physics.
We have a long term cooperation with the UT Department of Geography and Tartu Observatory and with the Estonian Weather Service. Our research is carried out in close cooperation with various international partners. We are open for cooperation in the fields of weather and climate research and applications.
