  1. 1. Modelling the early to mid-Holocene Arctic climate

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Marit Berger; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arctic; early Holocene; mid-Holocene; climate modelling; paleoclimate; sea ice; climate change;

    Sammanfattning : In the recent past it has become evident that the Earth's climate is changing, and that human activity play a significant role in these changes. One of the regions where the ongoing climate change has been most evident is in the Arctic: the surface temperature has increased twice as much in this region as compared to the global average, in addition, a significant decline in the Arctic sea-ice extent has been observed in the past decades.

  2. 2. On the Arctic Boundary Layer From Turbulence to Climate

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Thorsten Mauritsen; Stockholms universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atmospheric boundary layers; Turbulence; Stable stratification; Gravity waves; Mesoscale motion; Arctic climate; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The boundary layer is the part of the atmosphere that is in direct contact with the ground via turbulent motion. At mid-latitudes the boundary layer is usually one or a few kilometers deep, while in the Arctic it is much more shallow, typically a few hundred meters or less. LÄS MER

  3. 3. Isotope-based source apportionment of black carbon aerosols in the Eurasian Arctic

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Patrik Winiger; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Radiocarbon; Air Pollution; Arctic Amplification; Climate Change; Arctic Haze; Atmospheric Transport Modeling; Emission Inventory; Carbon Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosols change the Earth's energy balance. Black carbon (BC) aerosols are a product of incomplete combustion of fossil fuels and biomass burning and cause a net warming through aerosol radiation interactions (ari) and aerosol cloud interactions (aci). LÄS MER

  4. 4. On the recent Arctic Warming

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Rune Grand Graversen; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; atmospheric energy transport; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The Arctic region attracts considerable scientific interest in these years. Some of the Earth's most pronounced signs of the recent climate change are found here. The summer sea-ice cover is shrinking at an alarming rate. At the same time the region warms faster than the rest of the globe. LÄS MER

  5. 5. Ground freeze-thaw, snow and roads in northern Sweden

    Detta är en avhandling från Uppsala : Kulturgeografiska institutionen

    Författare :Maria Sarady; Uppsala universitet.; [2014]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ground freeze-thaw; snow depth; roads; northern Sweden; geography; Geography; Geografi;

    Sammanfattning : In this thesis freeze-thaw along roads in northern Sweden is examined. The examinations are put in a context of changing climate and its amplification towards the Arctic region on earth. The research focuses on the impact of a warmer climate on ground freeze-thaw and in exten- sion road maintenance in the region. LÄS MER
