This book was released on 1984 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doppler weather radar data from the Joint Airport Weather Studies (JAWS) Project are used to determine the horizontal and vertical structure of airflow within microbursts. Typically, the associated downdraft is about 1 km wide and begins to spread horizontally at a height below 1 km. The median time is 5 min from initial divergence at the surface to maximum different wind velocity across the microburst. The height of maximum differential velocity is 75 m. The median velocity different is 22 m/s over an average distance of 3.1 km. The outflow is assymetric, averaging twice as strong along the maximum shear axis compared to the minimum axis. Doppler radar could be an effective means for identifying microbursts and warning aircraft of wind shear hazards. For microburst detection such a radar must be able to measure wind velocities in clear air as well as heavy rain and hail. Scan update rates should be approximately every 2 min and the lowest few hundred meters of the atmosphere must be observed. Ground clutter must be considerably reduced from levels typically obtained with present Doppler radars.

Download or read book Airborne Doppler Radar Flight Experiments for the Detection of Microbursts written by Hans-J C. Blume and published by . This book was released on 1989 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the interest of aviation safety, NASA and the Federal Aviation Administration (FAA) are jointly conducting research to determine the applicability of airborne, coherent Doppler radar techniques to detect early microburst in wind shear conditions during aircraft takeoff and landing. If early detection of these severe wind shear conditions can be demonstrated, avoidance maneuvers can be exercised and significantly reduce the probability of aircraft disaster. Researchers have developed a computer model of the radar which predicts its response when viewing a simulated microburst against the simulated clutter background of an airport, the so-called radar-microburst-ground clutter model. Studies employing this model revealed that Doppler radar can accurately detect microburst ahead of the aircraft in time for pilot evasive response, but flight experiments will be required for complete performance evaluation of the system.

This book was released on 2018-07-17 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this analysis is to process Lincoln Laboratory Doppler radar data obtained during FLOWS testing at Huntsville, Alabama, in the summer of 1986, to characterize windshear events. The processing includes plotting velocity and F-factor profiles, histogram analysis to summarize statistics, and correlation analysis to demonstrate any correlation between different data fields.
