  1. 1. The Behaviour of the Latent Heat Exchange Coefficient in the Stable Marine Boundary Layer

    Uppsats för yrkesexamina på grundnivå, Institutionen för geovetenskaper

    Författare :Kristina Lindgren; [2008]
    Nyckelord :Latent heat flux; Sensible heat flux; Exchange coefficient; Neutral exchange coefficient; Turbulent Fluxes; Marine Boundary Layer; Stable Stratification; Air-sea interaction; Dimensionless profile functions; Östergarnsholm;

    Sammanfattning : Knowledge of the turbulent fluxes at the sea surface is important for understanding the interaction between atmosphere and ocean. With better knowledge, improvements in the estimation of the heat exchange coefficients can be made and hence models are able to predict the weather and future climate with higher accuracy. LÄS MER

  3. 2. Effects of Upwelling Events on the Atmosphere

    Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Susanna Hagelin; [2006]
    Nyckelord :upwelling; marine boundary layer; air-sea interaction; turbulent fluxes;

    Sammanfattning : During an upwelling event the cold bottom-water is brought to the sea surface. This cools the atmosphere from below and the stratification becomes more stable. When the atmosphere is more stable the turbulence is reduced and, as a consequence, so are the turbulent fluxes. LÄS MER

  4. 3. Evaluation of the Inertial Dissipation Method over Land

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Björn Carlsson; [2003]
    Nyckelord :inertial dissipation method; air-sea interaction; eddy correlation method; similarity theory;

    Sammanfattning : The focus was to evaluate the Inertial Dissipation Method (IDM) over land duringunstable conditions. This was done by comparing the friction velocity, u*, from theeddy-correlation method (ECM) with u* from IDM. LÄS MER

  5. 4. The Influence of Waves on the Heat Exchange over Sea

    Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Erik Sahlée; [2002]
    Nyckelord :air-sea interaction; turbulent fluxes; heat flux; swell; atmosphere-wave interaction; Stanton number;

    Sammanfattning : The main focus of this study is the influence of waves on the heat transfer over sea. In particular, the bulk transfer coefficient CH (the Stanton number), has been investigated for possible wave influence. Measurements from the site Östergarnsholm in the Baltic Sea have been used. The site has a large sector with undisturbed over water fetch. LÄS MER

  7. 5. Humidity Structures in the Marine Atmospheric Boundary Layer

    Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Andreas Svensson; [2002]
    Nyckelord :marine boundary layer; air-sea interaction; Dalton number; turbulent fluxes; quadrant analysis;

    Sammanfattning : The turbulence structure over the sea was studied with the emphasis on humidity. The data sets used came from the island of Östergarnsholm outside Gotland in the Baltic Sea. The study included spectral and quadrant analyses of the wind, temperature and humidity parameters from one measuring level. LÄS MER
