  1. 1. Global Climatology and Regional Modeling of Coastal Low-Level Jets

    Författare :Muhammad Raza Ranjha; Michael Tjernström; Gunilla Svensson; Branko Grisogono; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal low-level jets; climatology; regional modeling; boundary layer; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Localized coast-parallel wind-speed maxima at low altitude, known as coastal low-level jets (CLLJs) have important ramifications to the coastal climate and a number of human activities. This thesis documents the existence of the CLLJs around the globe including their mesoscale structure, dynamics and spatio-temporal variability. LÄS MER

  2. 2. On the Late Saalian glaciation : A climate modeling study

    Författare :Florence Colleoni; Martin Jakobsson; Johan Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate modeling; Eurasian ice sheet; Quaternary; Saalian; surface mass balance; SST; Earth sciences; Geovetenskap; Marine Geoscience; marin geovetenskap;

    Sammanfattning : This thesis focuses on the glaciation of the Late Saalian period (160 -140 ka) over Eurasia. The Quaternary Environment of the Eurasian North (QUEEN) project determined that during this period, the Eurasian ice sheet was substantially larger than during the entire Weichselian cycle and especially that of the Last Glacial Maximum (21 ka, LGM).

  3. 3. Modeling Carbon and Water Fluxes in European Terrestrial Ecosystems

    Författare :Pablo Morales; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climatology; Fysisk geografi; geomorphology; pedology; cartography; Physical geography; water fluxes; climate change; kartografi; geomorfologi; klimatologi; marklära; carbon fluxes; regional climate models; vegetation dynamics; ecosystem modeling;

    Sammanfattning : The controlling mechanisms and feedbacks between climate, the carbon and water cycling and vegetation in European ecosystems have attracted much attention in recent years but they are still not sufficiently understood. A better understanding of them is necessary to predict how they will be affected by climate change. LÄS MER

  4. 4. Energy systems analysis of Swedish pulp and paper industries from a regional cooperation perspective : Case study modeling and optimization

    Författare :Sofia Klugman; Bahram Moshfegh; Thore Berntsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy system; Optimization; District heating; Energy audit; Co-operation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The industrial sector uses about one third of the energy end-use in the world. Since energy use in many cases highly affects both the local and global environment negatively, it is of common interest to increase energy efficiency within industries. LÄS MER

  5. 5. Migration and Regional Sorting of Skills

    Författare :Sofia Tano; Thomas Aronsson; Olle Westerlund; Folmer Henk; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agglomeration; early markers; human capital; income; interregional migration; individual ability; location choice; marital matching; propensity score matching; regional clustering; skills; university graduates;

    Sammanfattning : This thesis consists of an introductory part and four papers.Paper [I] estimates jointly the choice of whether to enroll in education and the choice of location among young people. LÄS MER
