Correction of Dual PRF Velocity Errors for Operational Doppler Weather Radars
Publisher: American Meteorological Society
Abstract: Dual pulse repetition frequency (PRF) is a commonly used technique, in operational Doppler weather radar networks, that extends the unambiguous Doppler velocity. The technique requires the measurement of the radial velocity ...
Shipborne Polarimetric Weather Radar: Impact of Ship Movement on Polarimetric Variables at C Band
Publisher: American Meteorological Society
Abstract: he effect of ship motion on shipborne polarimetric radar measurements is considered at C band. Calculations are carried out by (i) varying the ?effective? mean canting angle and (ii) separately examining the elevation ...
Radar Characteristics of Storms in the Sydney Area
Publisher: American Meteorological Society
Abstract: The characteristics of radar echoes for 12 thunderstorm days in the vicinity of Sydney, Australia, in the summer of 1995/96 have been examined using an objective methodology for storm identification and tracking. The spatial ...
CPOL Radar-Derived Drop Size Distribution Statistics of Stratiform and Convective Rain for Two Regimes in Darwin, Australia
Publisher: American Meteorological Society
Abstract: This note builds on prior technique development related to the classification of rain types utilizing C-band polarimetric (CPOL) radar measurements. While the prior work was preliminary and limited in scope, the authors ...
Do We Observe Aerosol Impacts on DSDs in Strongly Forced Tropical Thunderstorms?
Publisher: American Meteorological Society
Abstract: ain drop size distributions retrieved from polarimetric radar measurements over regularly occurring thunderstorms over the islands north of Darwin, Australia, are used to test if aerosol contributions to the probability ...
Sensitivity Analysis of Polarimetric Variables at a 5-cm Wavelength in Rain
Publisher: American Meteorological Society
Abstract: Sensitivity of 5-cm-wavelength polarimetric radar measurements to raindrop size and distribution is investigated. At this wavelength, resonance occurs for sizes larger than about 5 mm, and therefore several polarimetric ...
Prospects for Temperature Sounding with Satellite and Ground-based RASS Measurements
Publisher: American Meteorological Society
Abstract: Temperature profiles from the TIROS-N Operational Vertical Sounder (TOVS) were combined with low-altitude virtual temperature profiles measured by a ground-based 915-MHz/2-kHz radio acoustic sounding system (RASS) at Denver, ...
Polarimetric Radar Measurements of Tropical Rain at a 5-cm Wavelength
Publisher: American Meteorological Society
Abstract: A 5-cm wavelength (C band) polarimetric radar was deployed during the MCTEX (Maritime Continent Thunderstorm Experiment) field program. This paper investigates the use of the C-band data for quantitative rainfall measurements ...
Quantification of Improvements in an Operational Global-Scale Ocean Thermal Analysis System
Publisher: American Meteorological Society
Abstract: Global-scale analyses of ocean thermal structure produced operationally at the U.S. Navy's Fleet Numerical Oceanography Center are verified, along with an ocean thermal climatology, against unassimilated bathythermograph ...
Using Dual-Polarized Radar and Dual-Frequency Profiler for DSD Characterization: A Case Study from Darwin, Australia
Publisher: American Meteorological Society
Abstract: Comparisons are made between the reflectivity Z, median volume diameter D0, and rain rate R from a dual-frequency profiler and the C-band polarimetric radar (C-POL), which are both located near Darwin, Australia. Examples ...
