11. Atlantic Water in the Nordic Seas : A satellite altimetry perspective on ocean circulation
Sammanfattning : The Atlantic Water in the Nordic Seas contributes to the mild climate of Northern Europe and is the main oceanic source of heat for the Arctic. The northward bound transport of the warm and saline Atlantic Water is mediated by a topographically constrained cyclonic boundary current along the Norwegian continental slope. LÄS MER
12. Dynamics and Variability of the Circulation in the North-Atlantic Subpolar Seas
Sammanfattning : This thesis deals with the dynamics and circulation in the northern North Atlantic and the Nordic Seas, processes of crucial importance for the mild climate of Scandinavia and Northern Europe. High-resolution ADCP scans of currents from Greenland to Scotland in the top 400 m demonstrate that the Reykjanes Ridge is a very effective separator of flow towards the Nordic and Labrador Seas, respectively.

13. A database of single scattering properties for hydrometeors at microwave and sub-millimetre frequencies
Sammanfattning : Remote sensing observations of hydrometeors (ice or liquid water particles) at microwave and sub-millimetre wavelengths provide important input to numerical weather forecasting through data assimilation and give insight to cloud processes that are relevant for climate prediction. The utilization of such measurements requires information on the single scattering properties (SSP), i. LÄS MER
14. Atmospheric dynamics and the hydrologic cycle in warm climates
Sammanfattning : Past warm climates represent one extreme of Earth's known climate states. Here, we study warm climates in both idealized simulations and full-complexity general circulation model (GCM) simulations of the early Eocene epoch, approximately 50 million years ago. LÄS MER
15. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets
Sammanfattning : Geomorphological evidence of glaciations exist for the Last Glacial Maximum (about 20 kyr ago). At this time, both North America and Eurasia were covered by extensive ice sheets which are both absent today. LÄS MER
