Meandering jet streams and propagating Rossby waves are responsible for the variable weather in the mid-latitudes. Moreover, extreme weather events such as heat waves and cold spells are part of the jet stream dynamics. For many years, a simple analog in the form of a simplified laboratory experiment, the differentially heated rotating annulus, has provided insight into the dynamics of the meandering jet stream. In the present study, probability density distributions of extreme events from a long-term laboratory experiment are studied and compared to the atmospheric probability density distributions. Empirical distributions of extreme value monthly block data are derived for the experimental and atmospheric cases. Generalized extreme value distributions are adjusted to the empirical distributions, and the distribution parameters are compared. Good agreement was found, but the distributions of the experimental data showed a shift toward larger extreme values, and some explanations for this shift are suggested. The results indicate that the laboratory model might be a useful tool for investigating changes in extreme event distributions due to climate change. In the laboratory context, the change can be modeled by an increase in total temperature accompanied by a reduction in the radial heat contrast.}, language = {en} } @misc{RoddaHarlanderVincze, author = {Rodda, Costanza and Harlander, Uwe and Vincze, Miklos}, title = {Jet stream variability in a polar warming scenario - a laboratory perspective}, series = {Weather and Climate Dynamics}, volume = {3}, journal = {Weather and Climate Dynamics}, number = {3}, issn = {2698-4016}, doi = {10.5194/wcd-3-937-2022}, pages = {937 -- 950}, language = {en} } @phdthesis{Rodda, author = {Rodda, Costanza}, title = {Gravity wave emission from jet systems in the differentially heated rotating annulus experiment}, edition = {1.

For many years scientists try to understand these flows by doing laboratory experiments. In the present paper we discuss two rather new laboratory experiments designed to study certain aspects of the atmospheric circulation. One of the experiments, the differentially heated rotating annulus at the Brandenburg University of Technology (BTU) Cottbus, has a cooled inner cylinder and a heated outer wall. However, the structure of the atmospheric meridional circulation motivates a variation of this "classical" design. In the second experiment described, operational at the Institute of Continuous Media Mechanics (ICMM) in Perm, heating and cooling is performed at different vertical levels that resembles more the atmospheric situation. Recent results of both experiments are presented and discussed. Differences and consistencies are highlighted. Though many issues are still open we conclude that both setups have their merits. The variation with heating and cooling at different levels might be more suited to study processes in the transition zone between pure rotating convection and the zone of westerly winds. On the other hand, the simpler boundary conditions of the BTU experiment make this experiment easier to control.}, language = {en} } @misc{VinczeHancockHarlanderetal., author = {Vincze, Miklos and Hancock, Cathrine and Harlander, Uwe and Rodda, Costanza and Speer, Kevin}, title = {Extreme temperature fluctuations in laboratory models of the mid-latitude atmospheric circulation}, series = {Scientific reports}, volume = {13 (2023)}, journal = {Scientific reports}, doi = {10.1038/s41598-023-47724-2}, pages = {13}, language = {en} }
