  1. 1. Model Studies of Surface Waves and Sediment Resuspension in the Baltic Sea

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Anette Jönsson; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface waves; Wave model; Wave friction velocity; Resuspension; Sediment dynamics; Nitrogen fixation; Baltic Sea; Havsvågor; Östersjön; Oceanografi; Sediment; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi;

    Sammanfattning : Wave heights and periods of surface waves in the Baltic Sea have been modelled for a two-year period (1999-2000) with the wave model Hypas on an 11x11-km grid scale. There is a clear seasonal variation with higher waves during winter and lower during summer. LÄS MER

  2. 2. On methods for estimating oceanic flow

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Jenny A. U. Nilsson; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean monitoring techniques; Barotropic flow; Baroclinic flow; Hydraulic theory; Baltic Sea; Bahía de Concepción; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi; Oceanography; oceanografi;

    Sammanfattning : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. LÄS MER

  4. 4. Freshwater, density gradients and biological processes in cold, brackish seas : aspects of the biogeophysical fluid dynamics characterising the Baltic Sea

    Detta är en avhandling från Stockholm : Department of Meteorology Stockholm University

    Författare :Tapani Stipa; Stockholms universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Östersjön; Oceanografi; meteorologi; Meteorology;

    Sammanfattning : The dominant component in the ocean water is freshwater. In this thesis its mixing and the freshwater-induced dynamics are discussed, with cold, brackish basins such as the Baltic Sea especially in mind. A mathematical framework is derived to allow for a consistent way of adding freshwater effects to the governing equations. LÄS MER

  5. 5. The influence of clouds on Earth's radiation budget in global climate models

    Detta är en avhandling från Stockholm : Department of Meteorology, Stockholm University

    Författare :Johannes Karlsson; Stockholms universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Considering the high sensitivity of climate to changes in cloudiness, the way clouds might change in a perturbed climate is important for the total temperature response. In fact, the cloud feedback has been identified as the main uncertainty in future projections, as simulated by global climate models. LÄS MER
