  1. 11. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation : Comparison of Methods and Climate Regions

    Författare :Fredrik Wetterhall; Sven Halldin; Chong-Yu Xu; Lars-Christer Lundin; Deliang Chen; Hans von Storch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Statistical; Downscaling; Precipitation; Large-scale circulation; PCA; TWS; Weather pattern; Regression; Weather generator; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale. LÄS MER

  3. 12. New insights into past atmospheric circulation dynamics

    Författare :Francesco Muschitiello; Barbara Wohlfarth; Richard Gyllencreutz; Qiong Zhang; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Climate change associated with shifts in atmospheric circulation patterns has a great influence on ecosystems and societies. To predict future climate change it is important to obtain a detailed understanding of how climate behaved in the past, with special focus on the regional-scale and short-term expressions of changes in atmospheric circulation dynamics.

  4. 13. Atlantic Water in the Nordic Seas : A satellite altimetry perspective on ocean circulation

    Författare :Sara Broomé; Johan Nilsson; Jonas Nycander; Léon Chafik; Michael A. Spall; Stockholms universitet; []
    Nyckelord :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;

    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

  5. 14. Ocean circulation in the Amundsen Sea, West Antarctica

    Författare :Ola Kalén; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean; currents; icebergs; remote sensing; ocean model;

    Sammanfattning : The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is assumed to be driven by the ocean. LÄS MER

  7. 15. Characterizing and reconstructing 500 years of climate in the Baltic sea Basin

    Författare :Christin Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate; Sea ice; Baltic Sea; Atmospheric circulation; Statistical modelling; Wavelet; River runoff;

    Sammanfattning : Climate has always attracted considerable interest, and climate observations have been made in various ways for most of human history. Regional climate and how it varies is of particular interest, as it sets the scene for our everyday life. LÄS MER
