  1. 36. Characterization and forecasting of wind conditions over the Baltic Sea

    Författare :Christoffer Hallgren; Erik Sahlée; Julie Lundquist; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; forecasting; low-level jet; lidar; machine learning; mesoscale meteorology; numerical weather prediction; post-processing; reanalysis; sea breeze; turbulence; wind atlas; wind energy; wind power; Meteorologi; Meteorology;

    Sammanfattning : To meet the increasing demand of sustainably produced electricity, the total number of installed wind turbines is rapidly increasing globally. Although onshore installations are dominating, offshore wind power is taking a greater share of the market every year. LÄS MER

  4. 38. Local Effects On Icing Forecasts for Wind Power In Cold Climate

    Författare :Erik Janzon; Anna Rutgersson; Metodija Shapkalijevski; Heiner Körnich; Johan Arnqvist; Alfredo Peña; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meteorologi; Meteorology;

    Sammanfattning : Understanding the risk of atmospheric icing on wind turbines is crucial for the operation of wind farms in cold climate regions. Processes leading to atmospheric icing in the planetary boundary layer are subject to interactions with the land surface--the details of which are largely unknown in current numerical weather prediction models and must be parameterized.

  5. 39. Modelling the middle atmosphere and its sensitivity to climate change

    Författare :Andreas Jonsson; Jörg Gumbel; Joanna Haigh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; middle atmosphere; ozone; carbon dioxide; stratosphere; mesosphere; chemical kinetics; atmospheric tides; Meteorology; Meteorologi;

    Sammanfattning : The Earth's middle atmosphere at about 10-100 km has shown a substantial sensitivity to human activities. First, the ozone layer has been reduced since the the early 1980s due to man-made emissions of halogenated hydrocarbons. LÄS MER

  7. 40. Some Concepts of Estuarine Modeling

    Författare :Bror Jönsson; Peter Lundberg; Kristofer Döös; Björn Kjärfve; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oceanography Modeling Estuaries; Meteorology; Meteorologi;

    Sammanfattning : If an estuarine system is to be investigated using an oceanographic modeling approach, a decision must be made whether to use a simple and robust framework based on e.g. mass-balance considerations, or if a more advanced process-resolving three-dimensional (3-D) numerical model are necessary.
