Network Wind Measurement in Complex Mountains

Programme overview

The conventional wind profile monitoring is mainly based on multi beam inversion calculation. The premise of measurement is that the horizontal wind field is uniform, while the horizontal wind field on the underlying surface of mountainous and urban complex terrain is uneven, especially near the ground. Therefore, in the detection of complex underlying surface, complex algorithm is often used to eliminate the turbulent data. However, the virtual tower (VT) technology, based on the cooperative observation of three lidars, enables the detection of the high-altitude wind field on complex underlying surface, without the premise that the horizontal wind field is uniform.


Features of the scheme

To study the wind field structure and evolution characteristics under the influence of complex terrain and atmospheric instability conditions, Leice team and Ocean University of China carried out the cooperative observation experiment with 3units of Wind3D 6000 scanning wind lidars, and compared the collaborative observation results with vertical lidar WindMast WP350 to verify the accuracy of synchronous observation.
