RISWind Profiler Observations of Tropical Storm Flo at Saipan
Publisher: American Meteorological Society
Abstract: Wind profiler and serial sounding observations extending to the upper troposphere are used to analyze Tropical Storm Flo (1990) as it passed within 115 km of the experimental site on Saipan. These data resolve details of ...
Classification of Precipitating Clouds in the Tropics Using 915-MHz Wind Profilers
Publisher: American Meteorological Society
Abstract: An algorithm has been developed that classifies precipitating clouds into either stratiform, mixed stratiform/convective, deep convective, or shallow convective clouds by analyzing the vertical structure of reflectivity, ...
Tropical Rainfall Associated with Convective and Stratiform Clouds: Intercomparison of Disdrometer and Profiler Measurements
Publisher: American Meteorological Society
Abstract: The motivation for this research is to move in the direction of improved algorithms for the remote sensing of rainfall, which are crucial for meso- and large-scale circulation studies and climate applications through better ...
Use of Two Profilers during MCTEX for Unambiguous Identification of Bragg Scattering and Rayleigh Scattering
Publisher: American Meteorological Society
Abstract: A 2835-MHz (10.6-cm wavelength) profiler and a 920-MHz (32.6-cm wavelength) profiler were collocated by the NOAA Aeronomy Laboratory at Garden Point, Australia, in the Tiwi Islands during the Maritime Continent Thunderstorm ...
Particle Size Estimation in Ice-Phase Clouds Using Multifrequency Radar Reflectivity Measurements at 95, 33, and 2.8 GHz
Publisher: American Meteorological Society
Abstract: Multifrequency radar measurements collected at 2.8 (S band), 33.12 (Ka band), and 94.92 GHz (W band) are processed using a neural network to estimate median particle size and peak number concentration in ice-phase clouds ...
Cluster Analysis Techniques to Separate Air Motion and Hydrometeors in Vertical Incident Profiler Observations
Publisher: American Meteorological Society
Abstract: Profilers operating in the UHF range are sensitive to both Bragg scattering from radio refractive index structure and to Rayleigh scattering from small point targets. Identification of the scattering process is critical ...
A Fuzzy Logic Method for Improved Moment Estimation from Doppler Spectra
Publisher: American Meteorological Society
Abstract: A new method for estimating moments from wind measurement devices that measure Doppler spectra as a function of range is presented. Quite often the spectra are contaminated by a wide variety of sources, including (but not ...
A 3-GHz Profiler for Precipitating Cloud Studies
Publisher: American Meteorological Society
Abstract: A 3-GHz profiler has been developed by the National Oceanic and Atmospheric Administration?s Aeronomy Laboratory to observe the evolution and vertical structure of precipitating cloud systems. The profiler is very portable, ...
Boundary Layer Development over a Tropical Island during the Maritime Continent Thunderstorm Experiment
Publisher: American Meteorological Society
Abstract: Data collected during the Maritime Continent Thunderstorm Experiment (MCTEX) (10 November?10 December 1995) have been used to analyze boundary layer development and circulations over two almost flat, tropical islands. The ...
Doppler Radar Profilers as Calibration Tools for Scanning Radars
Publisher: American Meteorological Society
Abstract: The National Oceanic and Atmospheric Administration?s Aeronomy Laboratory has modified a standard 915-MHz profiler for use as a precipitation profiler in support of Tropical Rainfall Measuring Mission ground validation ...
