Detecting Wind Shear and Turbulence at Hong Kong International Airport


To help pilots navigate through significant terrain-induced and convective wind shear and turbulence that occur along the flight paths due to the airport’s proximity to Lantau Island mountain peaks.


The Wind Shear & Turbulence Warning System
Between 1993 and 1997, NCAR researchers conducted a field program focused on wind flow over the mountainous terrain around Hong Kong's airport. This study was followed by the development of a warning system concept, feasibility studies, system design and development, testing, implementation and training. RAL scientists and engineers designed and developed the Wind Shear and Turbulence Warning System (WTWS)– Hong Kong.


This system generates alerts for easy interpretation by pilots, controllers, traffic managers and aviation forecasters and allows aircraft to operate safely when operating at this very busy international airport.
