Evaluation of Precipitation Measurements with the WSR-57 Weather Radar
Publisher: American Meteorological Society
Abstract: Quantitative data collected with the WSR-57 radar at Atlantic City from five rainstorms and two snow-storms are compared with precipitation data from 60 recording rain gages within 100 mi of the radar. Hourly rainfall ...
Similitude Laws and Small Scale Model Experiments Characterizing Dynamic Failures of Flawed Utility Poles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The principles of similitude were employed to scale the equations of motion of wood utility poles to small, practical laboratory size. The derived dimensionless system parameters were used to design experiments in which ...
Tornadogenesis by Nonprecipitation Induced Wind Shear Lines
Publisher: American Meteorological Society
Abstract: Five tornadoes occurred within a 40 min period on 18 May 1984 in eastern Colorado. The evolution of these tornadoes was documented by a single Doppler radar, research aircraft, mesonetwork and chase team. Three of these ...
Integration of Radar and Raingage Data for Improved Rainfall Measurement
Publisher: American Meteorological Society
Abstract: Oklahoma thunderstorm data were used to determine how the estimation of area rainfall by radar can be improved by using one or several raingages. The radar data were collected between 1964 and 1968 with the WSR-57 radar ...
Effect of Lake Ontario on Precipitation
Publisher: American Meteorological Society
Abstract: Radar and raingage data collected during the International Field Year for the Great Lakes were used to determine the effect of Lake Ontario on precipitation patterns. Objective analysis techniques were used to combine the ...
Use of Radar Summary Maps for Weather Analysis and Forecasting
Publisher: American Meteorological Society
Abstract: A study of radar summary maps collected from July to December 1961 shows that the echo areas reported are closely associated with precipitation and that the reported echo intensifies and heights of tops are valuable for ...
The Flare Echo: Reflectivity and Velocity Signature
Publisher: American Meteorological Society
Abstract: The characteristics and causes of a radar artifact called a flare echo are described. The spike or flare-shaped echo typically has reflectivities <20 dBZ, and approaching Doppler velocities. It extends radially 10?20 km ...
Radar in an Automated National Weather System
Publisher: American Meteorological Society
Abstract: Appropriate uses of radar in a national weather system within the next 10?15 years are considered. A radar network sensing precipitation reflectivity and utilizing many automatic techniques for acquiring and processing ...
