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

   Author : Annika E. Nilsson; Björn-Ola Linnér; Sofie Storbjörk; Oran R. Young; Linköpings universitet; []
   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

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

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

   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.

5. 3. Arctic Atmospheric Rivers : Eulerian and Lagrangian features, and trends over the last 40 years

   Author : Cheng You; Michael Tjernström; Abhay Devasthale; Heikki Järvinen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; Atmospheric river; Stratocumulus; Blocking; Turbulence; Longwave irradiance; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Arctic Atmospheric rivers, termed ‘warm-and-moist intrusion’ (WaMAI) in this thesis, transporting heat and moisture into the Arctic from lower latitudes, is a key contributor to the amplified warming in the Arctic under global change (Arctic Amplification). However, the warming effect of WaMAIs and its transformation along the trajectories into high Arctic still remain unclear, as well as their relation with the large-scale atmospheric circulation.

6. 4. The Arctic Summer Atmosphere

   Author : Cecilia Wesslén; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; meteorology; reanalysis; clouds; remote sensing;

   Abstract : The Arctic climate has experienced large changes over recent decades, the largest for any region on Earth. To understand the underlying reasons for this climate sensitivity, we need both models and observations. READ MORE

7. 5. Arctic Climate and Water Change : Information Relevance for Assessment and Adaptation

   Author : Arvid Bring; Georgia Destouni; Richard Lammers; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Monitoring; Arctic; Climate Change; Adaptatation; Physical Geography; naturgeografi;

   Abstract : The Arctic is subject to growing economic and political interest. Meanwhile, its water and climate systems are in rapid transformation. Relevant and accessible information about water and climate is therefore vital to detect, understand and adapt to the changes. READ MORE
