    Abstract : Popular Abstract in Swedish Arktis utgör en viktig del i Jordens miljö och vad som händer där har stor påverkan på det globala klimatet, samtidigt som området är mycket känsligt för förändringar. Under kvartärtiden har stora isar flera gånger täckt Skandinavien, Ryssland, Sibirien och Nordamerika och täcker än idag stora delar av Grönland. READ MORE

  2. 2. 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; Stockholms universitet.; [2016]
    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.

  3. 3. Paleoglaciology of the Tian Shan and Altai Mountains, Central Asia

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Robin Blomdin; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciology; glacial geomorphological mapping; cosmogenic nuclide dating; Tian Shan; Altai Mountains; Physical Geography; naturgeografi;

    Abstract : The mountain-systems of Central Asia, act as barriers to atmospheric circulation patterns, which in turn impose striking climate gradients across the region. Glaciers are sensitive indicators of climate change and respond to changes in climate gradients over time by advancing during cold and wet periods and receding during warm and dry periods. READ MORE
