Föhn events in southern Patagonia: characteristics and processes
Franziska Temme

The local climate in southern Patagonia is strongly influenced by the interaction between the topography and persistent westerlies, which can generate föhn events, dry and warm downslope winds. The upstream flow regime influences different föhn types which dictate the lee-side atmospheric response regarding the strength, spatial extent and phenomenology of the föhn winds. A combination of observations from automatic weather stations and high-resolution modeling with the Weather Research and Forecasting (WRF) model provides the opportunity to analyze the processes and the local impact of föhn events in southern Patagonia and on the Southern Patagonian Icefield.
This presentation summarizes the methodology and main results of the master thesis, together with further findings recently gained in an associated study.


High-Resolution Climatic Mass Balance of the 79°N glacier (Northeast Greenland)
Manuel Blau

The Nioghalvsfjerdsfjorden, also known as 79°N glacier , is a marine terminating glacier on 79°N glacier the northeast coast of Greenland. It is the largest outlet glaciers which is drained by the North East Greenland Ice Stream (NEGIS) and the largest discharge of the Greenland Ice Stream. It was believed stable in the 20th century but since the beginning of the 21st century, thinning and acceleration of the ice velocity of the 79°N glacier and of the entire NEGIS was observed. To better understand the climate-cryosphere interaction the surface, the climatic mass balance from 2014 to 2018 on high resolution (1km) was modeled by coupling the output of an atmospheric model with a mass balance model. Here, the output of the Weather Research and Forecasting model was used to force the COupled Snowpack and Ice surface energy and mass balance model in PYthon (COSIPY-WRF). In this presentation the methodology and the main results of a master thesis will be summarized.
