Development of an automated windshear detection system using Doppler weather radar
Article Abstract:
The US Federal Aviation Administration Terminal Doppler Weather Radar (TDWR) program is intended to provide a reliable automated Doppler radar-based system for detecting terminal weather hazards and warning pilots of the hazards. Low-altitude windshear has caused many aircraft fatalities in recent years, primarily through microburst, in which a downdraft from a convective cloud spreads out horizontally as it reaches the ground. The downdraft causes pilots flying into them to react to a strong headwind in a way that makes it difficult to react properly to the downdraft and tailwind that follow so quickly. The TDWR program is also intended to improve terminal-area operation management when bad weather hits. A pulse Doppler radar system at Denver's Stapleton airport led to the development of a fully automated terminal weather hazard detection radar system, the design of which is described.

Advances in weather technology for the aviation system
Article Abstract:
The US Federal Aviation Administration's national airspace plan for air traffic modernization and the National Weather Service's total revision of its weather observational capability will combine to improve the US aviation system considerably. The Next Generation Radar (NEXRAD) network of Doppler weather radars connects 150 radars throughout the US, but microburst wind shear cannot be detected by NEXRAD alone because of its radar scanning and siting limitations. The Terminal Doppler Weather Radar (TDWR) provides wind shear protection at about 50 US airports. The Automated Weather Observing System (AWOS) will consist of about 1,000 automated surface weather observing systems at small and medium-sized airports throughout the US. AWOS will provide pilots with minute-by-minute weather information. Several other weather measurement modernization programs are described.
