Uppsala University - Earth Sciences

Research area and research group

The wind energy research at the Uppsala University's Department of Earth Sciences studies both the wind profile and turbulence through measurements and simulation models. The Department has, in cooperation with WeatherTech Scandinavia, completed a mapping of Sweden's winds. Currently the group has research projects on the topics of wind power in forests, ice accumulation on wind turbines and sound propagation from wind turbines. 

Wind power research has been conducted since 1975. In the beginning the research was concentrated on the measurements: The first metmasts were built with the wind turbine Kalkungnen (35 m tall). Later a metmast was placed in Lappland's mountains near Suorva and a 140 meter metmast was placed in the forest near Ryningsnäs. A new 180 meter metmast is planned in cooperation with OX2 Wind AB on a forest covered hill in southern Sweden.
