RISThe Retrieval and Validation of Doppler Velocity Estimates from Range Imaging
Publisher: American Meteorological Society
Abstract: Range imaging (RIM) is used to describe a constrained optimization signal-processing method that can be applied to wind profilers capable of operating over a small set of distinct transmitter frequencies. The results of ...
Effects of Variations in Precipitation Size Distribution and Fallspeed Law Parameters on Relations between Mean Doppler Fallspeed and Reflectivity Factor
Publisher: American Meteorological Society
Abstract: A description is given of the influence of variations in the form of the hydrometeor particle size distribution and of variations in the form of the particle fallspeed law on relations between mean Doppler fallspeed vD and ...
Evaluation of an LES-Based Wind Profiler Simulator for Observations of a Daytime Atmospheric Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: The daytime atmospheric convective boundary layer (CBL) is characterized by strong turbulence that is primarily caused by buoyancy forced from the heated underlying surface. The present study considers a combination of a ...
A Combined Wind Profiler and Polarimetric Weather Radar Method for the Investigation of Precipitation and Vertical Velocities
Publisher: American Meteorological Society
Abstract: A method is presented by which combined S-band polarimetric weather radar and UHF wind profiler observations of precipitation can be used to extract the properties of liquid phase hydrometeors and the vertical velocity of ...
Evaluation of Weather Radar with Pulse Compression: Performance of a Fuzzy Logic Tornado Detection Algorithm
Publisher: American Meteorological Society
Abstract: Trends in current weather research involve active phased-array radar systems that have several advantages over conventional radars with klystron or magnetron transmitters. However, phased-array radars generally do not have ...
Implementation and Validation of Range Imaging on a UHF Radar Wind Profiler
Publisher: American Meteorological Society
Abstract: The available range resolution of pulsed radar wind profilers is usually limited by bandwidth restrictions. Range imaging (RIM) has recently been developed as a means of mitigating these limitations by operating the wind ...
First Frequency-Domain Interferometry Observations of Large-Scale Vertical Motion in the Atmosphere
Publisher: American Meteorological Society
Abstract: The spatiotemporal distribution of the vertical velocity at synoptic and subsynoptic scales is key to the patterns of weather and climate on earth. On these scales, the vertical velocity is on the order of one to a few ...
Potential Socioeconomic and Environmental Benefits and Beneficiaries of UAS Atmospheric Profiles from a 3D Mesonet
Publisher: American Meteorological Society
Prospects of the WSR-88D Radar for Cloud Studies
Publisher: American Meteorological Society
Abstract: ounding of nonprecipitating clouds with the 10-cm wavelength Weather Surveillance Radar-1988 Doppler (WSR-88D) is discussed. Readily available enhancements to signal processing and volume coverage patterns of the WSR-88D ...
A Time Series Sodar Simulator Based on Large-Eddy Simulation
Publisher: American Meteorological Society
Abstract: sodar simulator capable of producing time series data emulating sodar signals has been developed and tested. The atmospheric fields used to populate the sodar simulator are taken from output of a large-eddy simulation code. ...
