  1. 21. Simulations of Coastal Atmospheric Dynamics and Transport Processes

    Författare :Ragothaman Sundararajan; Dimitris Melas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; coastal atmosphere; dynamics; transport; Lagrangian particle dispersion model; mesoscale model; turbulence; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Sammanfattning : The marine atmosphere can be highly variable in space and time, and the coastal terrain plays a crucial role in influencing its properties. These, in turn, determine the atmospheric transport in the coastal zone. LÄS MER

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

    Författare :Xiaoli Guo Larsén; Sven-Erik Gryning; Uppsala universitet; []
    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. 23. Investigating aerosol effects on stratocumulus clouds through large-eddy simulation

    Författare :Ines Bulatovic; Annica Ekman; Caroline Leck; Ilona Riipinen; Daniel Grosvenor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particles; stratocumulus; mixed-phase clouds; cloud microphysics; cloud radiative effects; Arctic; Arctic amplification; LES; aerosolpartiklar; stratusmoln; underkylda vattendroppar och iskristaller; molnmikrofysik; molnstrålningseffekter; Arktis; ”large-eddy simulation”; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Clouds have a large impact on Earth’s radiative budget by reflecting, absorbing and re-emitting radiation. They thus play a critical role in the climate system. Nevertheless, cloud radiative effects in a changing climate are highly uncertain. LÄS MER

  5. 24. Biogenic Halocarbons in Polar Sea Ice

    Författare :Anna Granfors; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Sea ice; Antarctica; ice-air flux; gases;

    Sammanfattning : Sea ice is to date a rather poorly investigated part of the cycling of volatile halogenated organic compounds, halocarbons. These compounds are natural sources of reactive iodine and bromine to the atmosphere, and are produced in the marine environment. LÄS MER

  7. 25. Degradation of thermo-elastic properties in damaged composite laminates : a theoretical study

    Författare :Peter Lundmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Fiber composites are today widely used in different load carrying structures. The main reason is their high stiffness and strength to weight ratio. Due to these specific properties they are frequently used in car, marine and space industry. LÄS MER
