  1. 1. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

    Författare :Thanh Le; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

    Sammanfattning : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. LÄS MER

  3. 2. Modelling of the daytime and night-time urban thermal environment

    Författare :Shiho Onomura; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; urban thermal environment; microclimate modelling; air temperature; mean radiant temperature; nocturnal cooling rates; synoptic weather types;

    Sammanfattning : The world’s urban population is expected to increase over the coming decades. To maintain and improve the health and well-being of urban citizens, it is important to increase our knowledge and develop methods for evaluating the urban thermal environment to support urban planning.

  4. 3. High Temperature Corrosion Behaviour of Ni-base Alloys and FeCrAl Alloys – The Influence of Water Vapour

    Författare :Tommy Sand; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr-evaporation; FeCrAl alloy; Oxidation; Chromia scale; Alumina scale; High-temperature corrosion; Ni-base alloy;

    Sammanfattning : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. LÄS MER

  5. 4. On the atmospheric transport pathways of heat into the Arctic in winter and spring

    Författare :Sonja Murto; Rodrigo Caballero; Gunilla Svensson; Dörthe Handorf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic climate; Blocking; Warm-air intrusions; Surface energy budget; Melt onset; MOSAiC; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : The atmospheric meridional energy transport is an important component in the global climate system, as it transports moisture and heat from the midlatitudes into the Arctic, balancing the regional energy loss to space. Narrow and intense injections of warm and moist air, so-called warm-air intrusions, have a large local imprint on the surface through various processes acting on different scales, such as cloud formation, turbulent fluxes and atmospheric large-scale circulation.

  7. 5. Urban microclimate and surface hydrometeorological processes

    Författare :Christer Jansson; Per-Erik Jansson; David Gustafsson; Chen Delian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CoupModel; ENVI-met; roughness sub-layer; urban heat island; Physical geography; Naturgeografi;

    Sammanfattning : The urban near surface atmosphere is of great concern since it affects the climate to which an increasing amount of people are immediately exposed. This study investigated the microclimate in central Stockholm in terms of the thermal conditions in the 0-2. LÄS MER
