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

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

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

    Författare :Björn Carlsson; Anna Rutgersson; Ann-Sofi Smedman; Öyvind Saetra; Uppsala universitet; []
    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; Meteorology; 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

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

    Författare :Erik Sahlée; Ann-Sofi Smedman; Anna Rutgersson; Sören Larsen; Uppsala universitet; []
    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
