Moisture intrusions: Processes and climatological impacts (E04)

• Subject Area: Atmospheric Science
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 268020496

The poleward atmospheric energy transport plays a critical role for the seasonality and magnitude of Arctic temperature, and changes in this transport is one of the underlying mechanisms of Arctic amplification. This project aims to contribute to an improved understanding of such moisture intrusion events and thereby occurring air mass transformation processes. Our study on moisture intrusions will be by means of both an event-based (MOSAiC, HALO–(AC)3) and climatological analysis, and we combine both observations and modeling (ICON-LAM over circum-Arctic domain), and the Eulerian and Lagrangian approaches. Finally, future changes of moisture intrusions into the Arctic and their impacts will be considered.
