Real-time multiple single Doppler analysis with NEXRAD data
Summary
Summary
As part of the Aviation Weather Development Program of the Federal Aviation Administration, a high resolution winds analysis system was demonstrated at Orlando International Airport (MCO) in the summer of 1992. The purpose of this demonstration was to illustrate the winds analysis capability possible from operational sensors in the mid...
Automated gust front detection using knowledge-based signal processing
Summary
Summary
For reasons of aviation safety and airport operations efficiency, gust front detection and tracking is an important product of Doppler weather radars developed for use in airport terminal areas. Previous gust front algorithms, which have relied on the detection of one or two conspicuous signatures in Doppler radar imagery, have...
Impact of weather event uncertainty upon an optimum ground-holding strategy
Summary
Summary
When weather events are expected to produce significant delays at destination airports, the traffic flow management system in the United States holds departing aircraft on the ground in an attempt to reduce delay costs to the operator and to alleviate airborne congestion. Selecting the correct amount of ground holding is...
Results of simulation studies of precision runway monitoring of independent approaches to closely-spaced parallel runways
Summary
Summary
Increased air travel in recent years has resulted in a steady increase in the number and duration of flight delays. In an attempt to increase airport capacity, MIT Lincoln Laboratory, under the sponsorship of the Federal Aviation Administration (FAA), has supported the development of a Precision Runway Monitor (PRM). The...
Role of FAA/NWS terminal weather sensors and terminal air traffic automation in providing a vortex advisory service
Summary
Summary
The Federal Aviation Administration (FAA) is developing a number of terminal weather sensors and a terminal weather information system which can make important contributions toward an operational wake vortex advisory service. Although these systems have been developed to meet other important weather information needs, their existence/development offers the possibility of...
Development of a real-time ATC volcanic ash advisory system based on the aviation weather system
Summary
Summary
There is a need for a real-time volcanic ash advisory system for aviation which could provide improved accuracy and timeliness in warnings to planes in flight as well as to air traffic controllers for flight planning. To provide an operationally useful capability at reasonable cost, it is essential that the...
An experimental cockpit display for TDWR wind shear alerts
Summary
Summary
This paper describes an experimental system for cockpit display of Terminal Doppler Weather Radar (TDWR) wind shear warnings. The TDWR is a ground-based system for detecting wind shear hazards that pose a threat to aviation, During the Summer of 1990, wind shear warnings generated by the Lincoln-operated TDWR testbed radar...
Characteristics of gust fronts
Summary
Summary
A gust front is the leading edge of a thunderstorm outflow. A gust frontal passage is typically characterized by a drop in temperature, a rise in relative humidity and pressure, and an increase in wind speed and gustiness. Gust front detection is of concern for both Terminal Doppler Weather Radar...
Improvement in gust front algorithm detection capability using reflectivity thin lines versus azimuthal shears
Summary
Summary
Gust front detection is of concern for both Terminal Doppler Weather Radar (TDWR) and Next Generation Weather Radar (NEXRAD) systems. The automatic detection of gust fronts is desirable in the airport terminal environment because warnings of potentially hazardous gust front-related wind shears can be delivered to arriving and departing pilots...
A hybrid Cartesian windfield synthesis technique using a triple Doppler radar network
Summary
Summary
The estimation of air and particle motions in storms from multiple Doppler radar measurement is a long standing problem in radar meteorology. Our research interest in understanding the relationship of electrical change generation processes above the freezing level to thunderstorm life cycle, and in the detailed quantification of the eventual...
