    Abstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.

  2. 2. Non-dimensional gradient functions for water vapor and carbon dioxide in the marine boundary layer

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

    Author : Caroline Vahlberg; [2015]
    Keywords : Monin-Obukhov similarity theory; non-dimensional gradient functions; water vapor; carbon dioxide; marine boundary layer; turbulent fluxes; Monin-Obukhov similaritetsteori; dimensionslösa gradientfunktioner; vattenånga; koldioxid; marina gränsskiktet; turbulenta flöden;

    Abstract : A better understanding of the exchange processes taking place over the oceans is of great importance since the oceans cover about 70 % of the Earth’s surface. With better knowledge the turbulent fluxes can be more accurate parameterized, which is essential in order to improve the weather- and climate models. READ MORE

  3. 3. A Simple Method for Calculations of Wake Effects in Wind Farms with Influence of Atmospheric Stability

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

    Author : Anna Lewinschal; [2008]
    Keywords : vindkraftsmeteorologi; vak; effektutvinning;

    Abstract : Vindturbiner har vanligtvis byggts i kust- och jordbruksområden, men med en planerad utbyggnad av vindkraften i Sverige kommer nya platser behöva övervägas. En vindkraftpark placerad i inlandet kommer att påverkas av ett annorlunda vindklimat än en vindkraftpark i kustnära områden, främst på grund av högre turbulensintensitet och kraftigare vindskjuvning.
