An operational Windshear and Turbulence Warning System (WTWS) was developed for Hong Kong's NewAirport at Chek Lap Kok.  The WTWS provides alerts for terrain- and convective-induced windshear and turbulence. The system has been utilized by air traffic controllers and pilots since opening day, 6 July 1998. In addition to providing real-time windshear and turbulence alerts to controllers and pilots, the system provides up to 12-hour forecasts of terminal area turbulence to aviation meteorologists.

*Note:  The WTWS was previously known as the OWWS - the  Operational Windshear Warning System.
