  1. 1. A predictive numerical model of the atmospheric boundary layer based on the turbulent energy equation

    Författare :Svante Bodin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The atmospheric boundary layer has come into the focus of interest in recent years. Many areas of activity are dependent on accurate information about the boundary layer and prediction of its state. This is true in local weather forecasting, air pollution control and wind energy production. LÄS MER

  3. 2. Climate Related Thermal Actions for Reliable Design of Concrete Structures

    Författare :Oskar Larsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stress; solar radiation; FE-analysis; climate data; box-girder bridge; KstrConcrete; KstrReliability;

    Sammanfattning : When the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. LÄS MER

  4. 3. Climate change and urban drainage : future precipitation and hydraulic impact

    Författare :Mats Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Increasing global mean temperature influences the hydrologic cycle. In the 21st century, hydrologic change featuring more heavy precipitation events is very likely according to the UN Intergovernmental Panel on Climate Change, IPCC. This change will have a great impact on urban environments and infrastructures. LÄS MER

  5. 4. The use of a satellite-derived cloud climatology for studying cloud-aerosol processes and the performance of regional cloud climate simulations

    Författare :Karl-Göran Karlsson; Erland Källen; Jon-Egil Kristjansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clouds and climate; satellite cloud climatology; validation of clouds; clouds and aerosols; Meteorology; Meteorologi;

    Sammanfattning : The entry of satellite-derived decadal cloud datasets with homogeneous coverage in time and space enables studies not possible before. This thesis presents two such applications. The first study deals with cloud-aerosol processes and the second with an evaluation of cloud simulations from a regional climate model. LÄS MER

  7. 5. Flood Warnings in a Risk Management Context : A Case of Swedish Municipalities

    Författare :Erik Persson; Lars Nyberg; Inge Svedung; Charles Parker; Giuliano Di Baldassarre; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Early warning systems; floods; natural hazards; municipality; risk management; preparedness; disaster risk reduction.; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : As a result of the United Nations’ International Decade for Natural Disaster Reduction (1990-2000), and recent high profile disasters, disaster risk reduction has climbed high on the international political agenda. There has been a paradigm shift from reacting to disasters towards preparing for and mitigating effects of disasters. LÄS MER
