My research is focused on atmospheric dynamics and its interactions with the climate system, particularly with the ocean circulation, on seasonal to geologic time scales. Earth’s climate system is the promoter to balance the meridional temperature gradients between the tropical and polar regions. To achieve this the different components of the climate system, the atmospheric and ocean circulation, transport energy towards the poles. The atmospheric circulation is furthermore responsible for the distribution of water that results in the heterogeneous pattern of precipitation – and temperature – over the continents and oceans. Therefore, the variability of the atmospheric circulation and its drivers are crucial parameters of Earth’s climate system.
My primary focus is to investigate Holocene (the last 10,000 years) and late Quaternary (the last 600,000 years) climate and environmental dynamics in Europe by using state-of-the-art statistical methods (PC-PCA method) and by generating precisely dated high-resolution speleothem proxy time series. These analyses include also investigations if Holocene climate dynamics co-varied with cultural developments in Europe during the Holocene.
