Complete Polarimetric and Doppler Measurements with a Single Receiver Radar
Publisher: American Meteorological Society
Abstract: The concept of the polarimetric scattering matrix applicable to hydrometeors is reviewed to indicate the total number of measurands that is possible from a radar system with two orthogonal linear polarizations. It is shown ...
Weather Radar Polarimetry-Trends Toward Operational Applications
Publisher: American Meteorological Society
Abstract: This is a version of a speech presented at the 27th Conference on Radar Meteorology. Relative advantages of polarimetry are contrasted with the advantages accrued by the introduction of radar into meteorology and by the ...
Simulation of Weatherlike Doppler Spectra and Signals
Publisher: American Meteorological Society
Abstract: A versatile algorithm to generate weatherlike spectra of any desired shape is described, and applications are briefly discussed.
Automatic Detection of Gust Fronts
Publisher: American Meteorological Society
Abstract: We have developed a procedure that detects and tracks gust fronts automatically. It does not rely on a single method but requires simultaneous operation of two related algorithms. The convergence algorithm measures radial ...
Ground Clutter Filtering Dual-Polarized, Staggered PRT Sequences
Publisher: American Meteorological Society
Abstract: A procedure to filter the ground clutter from a dual-polarized, staggered pulse repetition time (PRT) sequence and recover the complex spectral coefficients of the weather signal is presented. While magnitude spectra are ...
Systematic Phase Codes for Resolving Range Overlaid Signals in a Doppler Weather Radar
Publisher: American Meteorological Society
Abstract: This paper deals with the recovery of Doppler velocities in the presence of range overlaid echoes. Transmitted pulses are phase shifted to tag the echoes from scatterers, which are separated by the unambiguous range. A new ...
Observations of Convective Thermals with Weather Radar
Publisher: American Meteorological Society
Abstract: AbstractIt is shown that the NEXRAD weather radar with enhanced detectability is capable of observing the evolution of convective thermals. The fields of radar differential reflectivity show that the upper parts of the ...
Comparison of Eddy Dissipation Rates from Spatial Spectra of Doppler Velocities and Doppler Spectrum Widths
Publisher: American Meteorological Society
Abstract: Doppler radars offer unique data from which it is possible to estimate the turbulent eddy dissipation rates, ?. If the inertial subrange extends to lengths longer than the radar resolution volume size, ? can be obtained ...
Correlation Analysis of Doppler Radar Data and Retrieval of the Horizontal Wind
Publisher: American Meteorological Society
Abstract: A technique for tracking patterns of radial velocity and reflectivity data obtained with a single-Doppler radar is described. Application of the technique to two different scans of the same spatial region may lead to the ...
Rain in Shallow and Deep Convection Measured with a Polarimetric Radar
Publisher: American Meteorological Society
Abstract: The authors contrast rainfall in two Oklahoma squall lines: one with deep convection occurred in the spring and the other with shallower convection in the winter. Both passed over a micronetwork of densely spaced rain ...
