1. Stormar i Sydsverige
Kandidat-uppsats, Lunds universitet/Fysiska institutionenSammanfattning : Many people believe that there are more windstorms today than before. In order to find out, it requires knowing what defines a windstorm: the average wind speed must exceed 24,4 m/s to be classed as a windstorm. The average wind speed is measured for a 10 minute period. LÄS MER
2. Uppskattning av vindklimat – Implementering och utvärdering av en metod för normalårskorrektion
Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : The expected technical lifetime for a wind turbine is 20-25 years (Wizelius, 2007). In the process of planning a wind farm on a site an estimation of the average wind speed and the energy yield is required from the site. LÄS MER
3. Downscaling of Wind Fields Using NCEP-NCAR-Reanalysis Data and the Mesoscale MIUU-Model
Magister-uppsats,Sammanfattning : The profitability from the production wind power energy is related to the quality of the wind speed forecasts. All wind predicting methods needs meteorological data, for the prevailing synoptic situation, as input. High quality input is wanted for a better result. LÄS MER
4. Methods for Estimating the Wind Climate Using The MIUU-model
Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : In the year 2002 the Swedish Energy Agency assigned the department of Earth science at Uppsala University a research assignment to make a detailed wind climatology mapping covering Sweden. A survey of the Swedish wind climate has been made earlier in some areas, using the Danish model WASP. LÄS MER
5. Wind throw damages on forests : frequency and associated pressure patterns 1961-1990 and in a future climate scenario
Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Many different simulations of the future climate have shown a probable change of the climate of the earth, mainly caused by anthropogenic emissions. A change in the climate influences many parameters. LÄS MER
