Publisher: American Meteorological Society
A New Relationship between Mean Doppler Velocity and Differential Reflectivity
Publisher: American Meteorological Society
Abstract: A new relationship has been established linking the vertical mean Doppler velocity of raindrop spectra and the accompanying differential reflectivities. It is based upon the specific radar combination of a vertically ...
Reflectivity, Rain Rate, and Kinetic Energy Flux Relationships Based on Raindrop Spectra
Publisher: American Meteorological Society
Abstract: The relationships between radar reflectivity factor Z, rainfall rate R, and rainfall kinetic energy flux E were analyzed based on a multiyear raindrop spectra dataset recorded by a Joss?Waldvogel disdrometer in the Goodwin ...
The 30th International Conference on Radar Meteorology
Publisher: American Meteorological Society
Abstract: The 30th International Conference on Radar Meteorology, held in Munich, Germany, 19?24 July 2001, highlighted recent progress in the field of radar meteorology and demonstrated how radar is used in many integrated ways to ...
Use of Three-Dimensional Reflectivity Structure for Automated Detection and Removal of Nonprecipitating Echoes in Radar Data
Publisher: American Meteorological Society
Abstract: This study aims at assessing the potential of anomalous propagation conditions to occur, reviews past attempts to mitigate ground clutter contamination of radar data resulting from anomalous signal propagation, and presents ...
Sensitivity of the Estimated Monthly Convective Rain Fraction to the Choice of Z–R Relation
Publisher: American Meteorological Society
Abstract: This study investigates the sensitivity of the estimated monthly convective rain fraction?that is, the percentage of the areal rain accumulation contributed by precipitation identified as convective?to variations of the ...
Scale Dependence of Radar-Rainfall Rates—An Assessment Based on Raindrop Spectra
Publisher: American Meteorological Society
Abstract: Scale differences may introduce a bias when comparing, merging, or assimilating rainfall measurements because the dynamic range of values representing the underlying physical process strongly depends on the resolution of ...
Variability of Raindrop Size Distributions in a Squall Line and Implications for Radar Rainfall Estimation
Publisher: American Meteorological Society
Abstract: The intrastorm variability of raindrop size distributions as a source of uncertainty in single-parameter and dual-parameter radar rainfall estimates is studied using time series analyses of disdrometer observations. Two ...
The Microphysical Structure of Extreme Precipitation as Inferred from Ground-Based Raindrop Spectra
Publisher: American Meteorological Society
Abstract: The controls on the variability of raindrop size distributions in extreme rainfall and the associated radar reflectivity?rain rate relationships are studied using a scaling-law formalism for the description of raindrop ...
A Microphysical Interpretation of Radar Reflectivity–Rain Rate Relationships
Publisher: American Meteorological Society
Abstract: The microphysical aspects of the relationship between radar reflectivity Z and rainfall rate R are examined. Various concepts discussed in the literature are integrated into a coherent analytical framework and discussed ...
