  1. 1. A Changing Arctic Climate Science and Policy in the Arctic Climate Impact Assessment

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Annika E. Nilsson; Björn-Ola Linnér; Sofie Storbjörk; Oran R. Young; [2007]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Arctic; climate; framing; knowledge production; regime; institution; actor network; co-production; indigenous knowledge; Arktis; klimat; kunskapsproduktion; regim; institution; aktörsnätverk; traditionell kunskap; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Climate change has often been framed as a global issue but slow progress in the global climate negotiations and an increasing need to plan for local adaptation have made it increasingly salient to also discuss the potential of other arenas for climate policy and knowledge production. This dissertation analyzes the interplay between science and policy at the international regional level based on a study of an assessment of the impacts of climate change in the Arctic. READ MORE

  2. 2. On the Arctic Seasonal Cycle

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Jonas Mortin; Gunilla Svensson; Rune G. Graversen; Wolfgang Dierking; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic climate; Seasonal melt-freeze transitions; Arctic sea ice and snow; Active microwave measurements; Climate model evaluation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The seasonal cycle of snow and sea ice is a fundamental feature of the Arctic climate system. In the Northern Hemisphere, about 55 million km2 of sea ice and snow undergo complete melt and freeze processes every year. READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Marit Berger; Arne Johansson; Rodrigo Caballero; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arctic; early Holocene; mid-Holocene; climate modelling; paleoclimate; sea ice; climate change;

    Abstract : 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.

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

    University dissertation from Stockholm : Meteorologiska institutionen (MISU)

    Author : Thorsten Mauritsen; Gunilla Svensson; Joao Teixeira; [2007]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. The Arctic Atmosphere Interactions between clouds, boundary-layer turbulence and large-scale circulation

    University dissertation from Stockholm, Sweden : Department of Meteorology, Stockholm University

    Author : Georgia Sotiropoulou; Michael Tjernström; Joseph Sedlar; Susanne Crewell; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; mixed-phase clouds; thermodynamic structure; Arctic inversion; cloud-surface interactions; seasonal transition; IFS model; LES; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Arctic climate is changing fast, but weather forecast and climate models have serious deficiencies in representing the Arctic atmosphere, because of the special conditions that occur in this region. The cold ice surface and the advection of warm air aloft from the south result in a semi-continuous presence of a temperature inversion, known as the “Arctic inversion”, which is governed by interacting large-scale and local processes, such as surface fluxes and cloud formation.
