North Atlantic Atmospheric Circulation Changes during Glacial and Interglacial Times

Tuesday, 16 January 2018, 16:45-17:45
KIT, Campus Süd, IMK-TRO, Geb. 30.23, 13.OG, Seminarraum
For the North Atlantic region, model simulations of the Last Glacial Maximum
(LGM, around 21,000 years before present) exhibit major differences in the 
atmospheric dynamics compared with today that are mostly attributed to changes 
in the topography.
The presentation will focus on these differences and showing first how 
atmospheric high frequency react on the different boundary condition 
during glacial times. In particular circulation types are used to better 
understand the precipitation changes simulated during the LGM. Then, the 
changes of eddy driven jet during the LGM are analyzed in details 
showing a southward shift of the jet position under glacial conditions. 
To  understand the underlying mechanisms for this shift both stationary 
and transient wave activity are identified to be relevant.
