  1. 1. Multi-satellite views on mesospheric microphysics and dynamics

    Författare :Lina Broman; Jörg Gumbel; Susanne Benze; Scott Bailey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polar mesospheric clouds; satellite tomography; remote sensing; cloud microphysics; wave dynamics; mesosphere; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Atmospheric gravity waves of different scales and origins strongly modulate the wind field and temperature structure of the higher parts of the atmosphere. Direct and continuous measurements of these processes are particularly complicated in the mesosphere at about 50 to 100 km height due to the remote location of this region. LÄS MER

  3. 2. Properties and Origin of Arctic Aerosols

    Författare :Ann-Christine Engvall; Jörg Gumbel; Frode Stordal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic aerosols; Arctic troposphere; air-mass transport; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The present thesis deals with the origin and physics of aerosols in the Arctic atmosphere. These show a large annual variability due to changes of the photochemical and cloud processes as well as of the synoptic-scale atmospheric pressure patterns. LÄS MER

  4. 3. Northern Hemispheric Cold Spells and their Tropospheric-Stratospheric Link

    Författare :Kathrin Finke; Abdel Hannachi; Jörg Gumbel; Alexey Karpechko; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Cold spells have severe consequences for society. They require early warnings for elaborate mitigation strategies on sub-seasonal to seasonal time-scales. LÄS MER

  5. 4. Some computational aspects of Markov processes

  7. 5. Numerical Modelling and Statistical Analysis of Ocean Wave Energy Converters and Wave Climates

    Författare :Wei Li; Isberg Jan; Jens Peter Kofoed; Uppsala universitet; []
    Nyckelord :Wave power; Wave energy converter; Gravity-based foundation; Power absorption; Wave spectrum; Linear generator; Frequency domain; Wave climate; Ocean wave modelling; Mixed-distribution model; Bivariate distribution; Archimedean copula;

    Sammanfattning : Ocean wave energy is considered to be one of the important potential renewable energy resources for sustainable development. Various wave energy converter technologies have been proposed to harvest the energy from ocean waves. This thesis is based on the linear generator wave energy converter developed at Uppsala University. LÄS MER
