Three dimensional airflow patterns within a coastal troughabowl blowout during fresh breeze to hurricane force winds

Wind flow within blowouts is extremely complex as streamline compression, expansion and reversal may occur over and around a single landform. As a result high resolution temporal and spatial measurements are required during a range of incident wind conditions to resolve near surface airflow patterns and turbulent structures. This study examined three-dimensional airflow within a coastal dune troughabowl blowout using 15 ultrasonic anemometers (UAs) and a high resolution computational fluid dynamics model.
