  1. 1. Air-Sea Fluxes of CO2 Analysis Methods and Impact on Carbon Budget

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Norman; Uppsala universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; air-sea exchange; carbon dioxide; Baltic Sea; eddy-covariance method; inertial dissipation method; cospectral-peak method; Baltic Sea measurements; CO2 fluxes; Galathea 3 expedition; Baltic Sea modeling; water-side convection; coastal upwelling; carbon budget; Meteorologi; Meteorology;

    Sammanfattning : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution.  The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans.

  2. 2. Air-sea exchange of O2 and CO2 Processes controlling the transfer efficiency

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Andreas Andersson; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; air-sea flux; oxygen; transfer velocity; water-side convection; Arctic; UVCN; Meteorologi; Meteorology;

    Sammanfattning : World oceans cover more than 70% of the earth surface and constitutes a major sink of atmospheric CO2. Two of the most important gases in the marine carbon cycling are O2 and CO2 and hence accurate descriptions of the air-sea gas exchange of these gases are crucial. LÄS MER

  3. 3. Air-Sea Exchange of Momentum and Sensible Heat Over the Baltic Sea

    Detta är en avhandling från Uppsala University Library

    Författare :Xiaoli Guo Larsén; Uppsala universitet.; [2003]
    Nyckelord :Meteorology; meteorologi;

    Sammanfattning : Long term measurements are used to explore the wave impact on the momentum and sensible heat transfer in the marine atmospheric surface layer. This is important in determining the boundary conditions of atmosphere-ocean coupled models of many scales. LÄS MER

  4. 4. Implementation and Analysis of Air-Sea Exchange Processes in Atmosphere and Ocean Modelling

    Detta är en avhandling från Uppsala : Universitetsbiblioteket

    Författare :Björn Carlsson; Uppsala universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sensible heat flux; Latent heat flux; Momentum flux; Wind stress; Marine boundary layer; Air–Sea interaction; Swell; Climate model; Ocean model; Roughness parameter; Drag coefficient; Wave breaking; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi;

    Sammanfattning : To understand and to predict the weather and climate, numerical models are important tools and it is crucial that the controlling processes are described correctly. Since 70% of the global surface is covered with water the description how the ocean and atmosphere communicates has a considerable impact. LÄS MER

  5. 5. Fluxes of Sensible and Latent Heat and Carbon Dioxide in the Marine Atmospheric Boundary Layer

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Sahlée; Uppsala universitet.; [2007]
    Nyckelord :Meteorology; Sensible heat flux; Latent heat flux; Carbon dioxide; Turbulent exchange; Global heat fluxes; Marine boundary layer; Air-sea interaction; Meteorologi;

    Sammanfattning : Oceans cover about 70% of the earth’s surface. They are the largest source of the atmospheric water vapour and act as enormous heat reservoirs. Thus in order to predict the future weather and climate it is of great importance to understand the processes governing the exchange of water vapour and heat between the ocean and atmosphere. LÄS MER
