  1. 1. Non-dimensional gradient functions for water vapor and carbon dioxide in the marine boundary layer

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Caroline Vahlberg; [2015]
    Keywords : Monin-Obukhov similarity theory; non-dimensional gradient functions; water vapor; carbon dioxide; marine boundary layer; turbulent fluxes; Monin-Obukhov similaritetsteori; dimensionslösa gradientfunktioner; vattenånga; koldioxid; marina gränsskiktet; turbulenta flöden;

    Abstract : A better understanding of the exchange processes taking place over the oceans is of great importance since the oceans cover about 70 % of the Earth’s surface. With better knowledge the turbulent fluxes can be more accurate parameterized, which is essential in order to improve the weather- and climate models. READ MORE

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

    University essay from Institutionen för geovetenskaper

    Author : Kristina Lindgren; [2008]
    Keywords : 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;

    Abstract : 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.

  3. 3. Humidity Structures in the Marine Atmospheric Boundary Layer

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE

  4. 4. The wind field in coastal areas

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Niklas Sondell; [2001]
    Keywords : coastal meteorology; internal boundary layer; effect of surface properties; wind field; stability effects;

    Abstract : The land-sea transition in coastal areas makes the meteorological conditions rather complex and the structure of the coastal boundary layer is important for many reasons. Two examples are air pollution dispersion and wind energy potential. The wind field off the coast when offshore flow is present has been studied. READ MORE
