  1. 1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Charlotte Sophie Gausa; [2024]
    Nyckelord :Arctic; wind profile power law; MOST; boundary layer; low level jets; sea ice; vindprofil; Arktis; gränsskikt; vindenergi; låghöjdsvindar; havsis;

    Sammanfattning : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

  3. 2. Norra polcirkelns uppvärmning och ännu varmare maktkapplöpning

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Ulf Liljedahl; [2024]
    Nyckelord :Klimatförändringar; Arktis; Geopolitik; Internationella relationer; Realism; Liberalism; The Arctic five; Law and Political Science;

    Sammanfattning : Today the climate in the arctic regions are changing at a rapid rate, faster than any speed previously recorded in human history but how is it impacting the geopolitical situation in these regions? New territory is being created by the ice melting and new natural resources are being found, how can this impact the current situation? This study looks at and discusses the current geopolitical situation in the Arctic using two theories from international relations, realism and liberalism and how the situation can develop using these theories. From a realist standpoint it is a balance of power held in check primarily by nuclear weapons. LÄS MER

    Sammanfattning : This thesis examines how the Arctic region is portrayed and constructed as a security matter within Swedish state discourses from 2020 to 2023. Focused on the escalating geopolitical significance and the transformative impact of climate change in the Arctic, the thesis scrutinizes Sweden's portrayal of security in the region. LÄS MER

  5. 4. Trends in mountain birch seed abundance and its relation to temperature and moth abundance: a ten-year study from Swedish Lapland

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Frida Gustafsson; [2023-02-09]
    Nyckelord :Betula pubescens; climate change; seed production; Epirrita autumnata; Operophtera brumata; subarctic ecology; folivory; larval abundance;

    Sammanfattning : Boreal forest is the world’s largest terrestrial biome. Being one of the most ubiquitous and coldtolerant tree species in Sweden, the mountain birch forms a unique deciduous treeline and marks the forest-tundra ecotone. LÄS MER

  7. 5. The implications of heavy fuel oil ban in arctic waters for sustainable arctic shipping

    Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

    Författare :Kaung Thu; [2023-01-23]
    Nyckelord :Arctic region; heavy fuel oil; shipping; Sustainable;

    Sammanfattning : The increased temperature in the polar regions is one of the significant impacts of global warming and consequential climate change. In the Arctic, regional warming leads to the accelerated loss of sea ice caps, which has opened up new international shipping routes. LÄS MER
