  1. 1. Evaporation Duct Modelling for a Wave-Propagation Simulator

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Oscar Eklund; [2022]
    Nyckelord :evaporation; duct; height; monin; obukhov; mos; surface; layer; ssft; byc; pj; businger; dyer; beljaars; holtslag; cheng; brutsaert; sheba;

    Sammanfattning : Long-range communication proves to be a challenge due to the Earth’s curvature, since electromagnetic waves propagate away from the Earth’s surface in a free atmosphere. A possible solution to beyond line-of-sight communication is the atmospheric phenomenon known as the evaporation duct. LÄS MER

  3. 2. Comparison of intensified turbulence events in the Baltic Sea

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Linnéa Hallgren; [2021]
    Nyckelord :turbulence; upper ocean; ocean mixing; parameterization;

    Sammanfattning : Turbulence is important since it affects the exchange of momentum, heat, and trace gases between the atmosphere and the ocean. However, measuring oceanic turbulence is not straightforward and that is why parameterizations that describe turbulence events are important. LÄS MER

  4. 3. The effect of tropical cyclones on the carbon cycle

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Brendan Bos; [2017]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : Tropical cyclones influence processes within the carbon cycle on different time-scales. Forested ecosystems suffer windfall and long-term impacts from tropical cyclones, leading to the release of CO2 to the atmosphere. LÄS MER

  5. 4. 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

  7. 5. 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
