Dynamic meteorology: midlatitude circulation; large-scale atmospheric circulation regimes; atmospheric stationary waves; flow-topography interactions; Rossby-wave breaking; critical layer reflection; wave guides; jet stream and storm track dynamics; atmosphere–ocean–land–ice-sheet interactions Climatology: atmospheric and oceanic circulation regimes; sea-level rise from melting polar ice sheets; climate feedbacks
Paleo-climatology: atmospheric and oceanic circulation regimes in warm and cold climates; the LGM climate, the pre-LGM glacial climate; the mutual interaction between continental-scale ice sheets and the time-mean atmospheric circulation; conditions for glacial inception: local climate conditions, connection to atmospheric and oceanic circulation regimes, the importance of Arctic gateways for the North Atlantic climate; jet streams and storm tracks in past climates
Numerical modeling: model development and optimization; model hierarchies and applications; biases in climate/circulation models (from idealized/simplified to comprehensive general circulation models)
