Estimating Turbulence Intensity along Flight Paths in Terrain-disrupted Airflow Using Anemometer and Wind Profiler Data
نویسندگان
چکیده
Timely alerting of turbulence is crucial to assuring flight safety. In the existing Windshear and Turbulence Warning System (WTWS) operated by the Hong Kong Observatory (HKO), turbulence along flight paths, which is quantified in terms of the cube root of Eddy Dissipation Rate (edr 1/3 ) following international aviation practice, is estimated from the data of surface anemometers in the vicinity of the airport and on the hills nearby, based on correlation equations established from a limited number of turbulent flow events collected by a research aircraft before the opening of HKIA in 1998 (Neilley, 1995).

Wind in Complex Terrain - Lidar Measurements for Evaluation of CFD Simulations
Computational Fluid Dynamics (CFD) is widely used to predict wind conditions for wind energy production purposes. However, as wind power development expands into areas of even more complex terrain and challenging flow conditions, more research is needed to investigate the ability of such models to describe turbulent flow features. In this study, the performance of a hybrid Reynolds-Averaged Nav...
متن کاملDetermination of Richardson number profile from remote sensing data and its aviation application
A number of remote-sensing wind-measuring instruments, such as LIDAR and radar wind profilers, have been set up in the vicinity of the Hong Kong International Airport (HKIA) for monitoring of low-level windshear and turbulence. The combined usage of wind data from a radar wind profiler and boundary layer temperature profiles from a ground-based microwave radiometer in turbulence application is ...
متن کاملWind Actions and Responses of Steel Chimneys
Understanding some of the basic wind engineering concepts helps one understand the chimney’s response. The circular cross section of the steel chimney characteristically provides aerodynamic lift perpendicular to the wind direction. Knowing how to predict and prevent these adverse responses is of critical importance to steel chimney design. I. STATIC WIND FORCES The force exerted by wind varies...
