Abstract

In this paper, we demonstrate the application of X-band TerraSAR-X (TS-X) data with high spatial resolution for studies on wind turbine wake in the near and far field of the offshore wind farm Alpha Ventus located in the North Sea. Two cases which have different weather conditions and yield different wake pattern as observed in the TS-X image are presented. Using the TS-X observations, the retrieved sea surface wind field and meteorological measurements at the FiNO1 platform jointly, we quantify the wake characteristics of wake length, wake width, maximum velocity deficit, wake merging and wake meandering. Influences of meteorological conditions on inducing wakes with different characteristics in the two cases are discussed.
