RISRetrieval of Horizontal Wind Field and Mesoscale Vertical vorticity in Stratiform Precipitation by Conical Scannings with Two Doppler Radars
Publisher: American Meteorological Society
Abstract: Stratiform precipitations associated with fronts and squall lines are commonly observed by means of a single Doppler radar operating conical scannings. The data analysis is frequently the Velocity Azimuth Display?or ...
Three-Dimensional Air Circulation in a Squall Line from Airborne Dual-Beam Doppler Radar Data: A Test of Coplane Methodology Software
Publisher: American Meteorological Society
Abstract: The detailed structure of a tropical squall line observed in central Florida was investigated from an airborne dual-beam Doppler radar, pointing respectively fore and aft. This allowed dual-Doppler observations from a ...
Stereoradar Meteorology: A New Unified Approach to Process Data from Airborne or Ground-Based Meteorological Radars
Publisher: American Meteorological Society
Abstract: The concept of stereoradar in meteorology was first proposed by Testud and Amayenc. It consists of radar observations of a precipitation cell from two viewing angles, using an attenuated frequency. The initial inspiration ...
Estimate of Precipitation from the Dual-Beam Airborne Radars in TOGA COARE. Part 1: The K–Z Relationships Derived from Stereo and Quad-Beam Analysis
Publisher: American Meteorological Society
Abstract: The recent development of dual-beam airborne Doppler weather radar offers the possibility to perform high-resolution observations of the three-dimensional air motion and precipitation fields associated with severe weather ...
Rainfall-Rate Retrieval from a Spaceborne Radar: Comparison between Single-Frequency, Dual-Frequency, and Dual-Beam Techniques
Publisher: American Meteorological Society
Abstract: This paper investigates the performances achievable in the retrieval of rain-rate profile from a spaceborne radar operating at attenuated frequencies. Results obtained from three radar systems using relevant range-profiling ...
Proposal for a Spaceborne Dual-Beam Rain Radar with Doppler Capability
Publisher: American Meteorological Society
Abstract: The potential characteristics and performances of a spaceborne dual-beam radar (or stereo radar) operating at 24 GHz, and devoted primarily to the retrieval of rain-rate structure by using the stereo-radar analysis, were ...
Estimate of Precipitation from the Dual-Beam Airborne Radars in TOGA COARE. Part II: Precipitation Efficiency in the 9 February 1993 MCS
Publisher: American Meteorological Society
Abstract: Dual-beam airborne Doppler radars are commonly used in convection experiments for their ability to describe the dynamical structure of weather systems. However, instrumental limitations impose the use of wavelengths such ...
Study and Tests of Improved Rain Estimates from the TRMM Precipitation Radar
Publisher: American Meteorological Society
Abstract: Rain rate R estimation from the 2A-25 profiling algorithm of the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) is analyzed in two ways. Standard results from the operating version-5 algorithm are ...
A Tropical Squall Line Observed during the COPT 81 Experiment in West Africa. Part 1: Kinematic Structure Inferred from Dual-Doppler Radar Data
Publisher: American Meteorological Society
Abstract: This paper deals with the analysis of a tropical squall line, observed on 22 June 1981 during the COPT 81 (Convection Profonde Tropicale) experiment. The present Part I is restricted to the study of the kinematic structure ...
The Rain Profiling Algorithm Applied to Polarimetric Weather Radar
Publisher: American Meteorological Society
Abstract: The algorithm developed in this paper for ground-based polarimetric radars is derived from those used for the spaceborne rain radar of TRMM (Tropical Rainfall Measurement Mission)?the so-called rain profiling algorithms. ...
