  2. 11. Atlantic Water in the Nordic Seas : A satellite altimetry perspective on ocean circulation

    Author : Sara Broomé; Johan Nilsson; Jonas Nycander; Léon Chafik; Michael A. Spall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean climate; ocean heat transport; sea surface height; topographic control; Lagrangian trajectories; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : 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. READ MORE

  4. 12. Dynamics and Variability of the Circulation in the North-Atlantic Subpolar Seas

    Author : Léon Chafik; Nilsson Nilsson; Tore Furevik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : 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.

  5. 13. A database of single scattering properties for hydrometeors at microwave and sub-millimetre frequencies

    Author : Robin Nils Ekelund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sub-millimetres; Hydrometeors; microwaves; clouds; single scattering properties; satellites.; remote sensing; water vapour;

    Abstract : 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. READ MORE

  6. 14. Atmospheric dynamics and the hydrologic cycle in warm climates

    Author : Henrik Carlson; Rodrigo Caballero; Johan Nilsson; Jonathan L. Mitchell; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superrotation; early Eocene; warm climates; Madden-Julian Oscillation; the hydrologic cycle; vegetation sensitivity; large-scale circulation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : 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. READ MORE

  7. 15. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets

    Author : Johan Liakka; Johan Nilsson; Johan Kleman; Gerard Roe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmospheric stationary waves; Paleo ice sheets; Ice-sheet ablation; Atmosphere-ice sheet modelling; Climatology; Klimatologi; Meteorology; Meteorologi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : 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. READ MORE
