  1. 1. Meteorological Investigation of Preconditions for Extreme-Scale Wind Turbines in Scandinavia

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

    Author : Christoffer Hallgren; [2013]
    Keywords : extreme-scale wind turbines; wind power; wind power density; wind atlas; MERRA; reanalysis data; extremskaliga vindkraftverk; vindkraft; vindenergidensitet; vindatlas; MERRA; återanalysdata;

    Abstract : During the last three decades, the hub height of wind turbines has increased from 24 to 162 meters and with an increasing demand for break-through innovations in green energy production it seems likely that this trend will continue. The meteorological preconditions for extreme-scale wind turbines are investigated for Scandinavia using 33 years of reanalysis data from MERRA (Modern-Era Retrospective Analysis for Research and Applications).

  3. 2. Regional Precipitation Study in Central America, Using the WRF Model

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

    Author : Tito Maldonado; [2012]
    Keywords : WRF; Central America; precipitation; dynamical downscaling; regional models; reanalysis; cumulus parameterization schemes.; WRF; Centralamerika; nederbörd; dynamiska nedskalning; regionala modeller; reanalys; cumulus parametrisering system;

    Abstract : Using the regional climate model WRF, and the NCEP-NCAR Reanalysis Project data asboundary and initial conditions, regional precipitation was estimated by means of thedynamical downscaling technique for two selected periods, January 2000 and September2007. These months show very particular climatic characteristics of the precipitationregimen in Central America, like dry (wet) conditions in the Pacific (Caribbean) coast of theCentral American isthmus, in January, and wet (dry) conditions, respectively in each coast,during September.

  4. 3. Wind Climate Estimates - Validation of Modelled Wind Climate and Normal Year Correction

    University essay from Luft- och vattenlära

    Author : Martin Högström; [2007]
    Keywords : Modelled Wind Climate; MIUU-model; Normal Year Correction; Wind Energy;

    Abstract : Long time average wind conditions at potential wind turbine sites are of great importance when deciding if an investment will be economically safe. Wind climate estimates such as these are traditionally done with in situ measurements for a number of months. READ MORE
