  1. 41. Tree Rings as Sensitive Proxies of Past Climate Change

    Författare :Håkan Grudd; Wibjörn Karlén; Brian Luckman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; Physical geography; Naturgeografi;

    Sammanfattning : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. LÄS MER

  3. 42. Hygrothermal Simulations of Buildings Concerning Uncertainties of the Future Climate

    Författare :Vahid Nik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould growth; climate change; climate uncertainties; hygrothermal simulation; energy demand;

    Sammanfattning : Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. LÄS MER

  4. 43. Windstorms in Sweden - variations and impacts

    Författare :Carin Nilsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate impact; geostrophic wind; Gudrun; Anatol; wind throw; forest damage; storm damage; Sweden; wind climate; windstorm;

    Sammanfattning : Windstorms have caused severe damage on several occasions in Sweden during the last century. A general concern about future projections of climate extremes has raised questions on the variations and impacts of windstorms. LÄS MER

  5. 44. Urban Design and Outdoor Thermal Comfort in Warm Climates. Studies in Fez and Colombo

    Författare :Erik Johansson; Boende och bostadsutveckling; []
    Nyckelord :HUMANIORA; HUMANITIES; marklära; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Physical geography; Urban planning; Urban design; Urban climate; Tropical areas; Thermal comfort; Sri Lanka; Planning regulations; Morocco; Microclimates; Land-use; Fez; Humid tropics; Colombo; Developing countries; Climatic design; Climate; Arid zones; Built environment; Physical planning; kartografi; klimatologi; Town and country planning; Stads- och glesbygdsplanering; Fysisk planering;

    Sammanfattning : In many developing tropical countries, rapid urban growth leads to several problems, including increased thermal stress. This has negative consequences for people's health and well-being, and affects social and commercial outdoor activities negatively. LÄS MER

  7. 45. Ecology of zooplankton communities: climate, dormancy, and benthic-pelagic coupling

    Författare :Mikael Gyllström; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; limnologi; akvatisk ekologi; limnology; Hydrobiology; marine biology; aquatic ecology; phytoplankton; temporal stability; recruitment; seasonal succession; environmental cues; diapause; shallow lakes; predation; enrichment; climate; temperature;

    Sammanfattning : This thesis describes how influences, such as top down and bottom up forces, shape zooplankton communities in shallow lakes. I have also extended the traditional food-web theory by investigating the effects of climate on total biomass, taxonomic composition, and temporal properties of zooplankton communities. LÄS MER
