Met Mast Array to measure high temporal and spatial resolution wind fields — •Abdulkarim Abdulrazek, Joachim Peinke, and Michael Hölling — ForWind, Institute of Physics, University of Oldenburg, Oldenburg, Germany

Atmospheric wind fields are turbulent, in which the flow frequently changes speed and direction, creating a sudden increase of wind speed and generation of vortices. Such turbulent flows can affect for example wind turbine loads and performance causing damages resulting in expensive downtimes. In order to study these effects, a met mast array consisting of three meteorological masts will be installed between two wind turbines. The mast array will be equipped with up to XX ultrasonic and cup anemometers. The challenge is how to distribute these anemometers in horizontal and vertical direction to achieve high resolution in time and space. On the poster we will present the concept of the layout of the anemometers based on the detailed analysis of already existing atmospheric measurements data. Therefore, we propose an unevenly distributed arrangement of the anemometers in two dimensions. The anemometers will be distributed according to scaling factor of 2.52n on the three masts which should extract an optimal amount of information on a large range of scales as well as capture finer wind variations and vortices of different sizes.
