  1. 1. Water and heat exchange processes over the Baltic sea

    Författare :Anna Rutgersson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Sammanfattning : Before we can reach understanding of the global climate and predict climate changes accurately we must be able to understand water and energy budgets. The atmosphere-water exchange processes are of great importance. LÄS MER

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

    Författare :Andreas Andersson; Anna Rutgersson; Brian Ward; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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. 3. Mean Wind and Turbulence Conditions in the Boundary Layer above Forests

    Författare :Johan Arnqvist; Hans Bergström; Anna Rutgersson; Stefan Söderberg; Søren Larsen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Wind power; Forest; Turbulence; Waves; Spectra; Wind model; Atmospheric stability; Vindkraft; Skog; Turbulens; Vågor; Spektra; Modell; Atmosfärisk stabilitet;

    Sammanfattning : As wind turbines have grown, new installation areas become possible. Placing wind turbines in forested landscapes introduce uncertainties to the wind resource estimation. LÄS MER

  4. 4. 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 :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Wind Turbine Sound in Cold Climates

    Författare :Kristina Conrady; Anna Rutgersson; Karl Bolin; Sabine von Hünerbein; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; atmospheric acoustics; wind turbine sound; outdoor sound propagation; cold climates; Meteorology; Meteorologi;

    Sammanfattning : The increase in the number of wind turbines (WTs) in populated areas in cold climates increases the number of people potentially being affected by WT sound. Outdoor sound propagation is strongly dependent on meteorological conditions, however, limitations in the knowledge exist regarding the implications of meteorological conditions in cold climates.
