On the Use of Radiosondes in Freezing Precipitation
Publisher: American Meteorological Society
Abstract: AbstractRadiosonde observations are used the world over to provide critical upper-air observations of the lower atmosphere. These observations are susceptible to errors that must be mitigated or avoided when identified. ...
Electrification of Stratiform Regions in Mesoscale Convective Systems. Part II: Two-Dimensional Numerical Model Simulations of a Symmetric MCS
Publisher: American Meteorological Society
Abstract: Model simulations of a symmetric mesoscale convective system (MCS; observations discussed in Part I) were conducted using a 2D, time-dependent numerical model with bulk microphysics. A number of charging mechanisms were ...
Electrification of Stratiform Regions in Mesoscale Convective Systems. Part I: An Observational Comparison of Symmetric and Asymmetric MCSs
Publisher: American Meteorological Society
Abstract: The kinematic, microphysical, and electrical structures of two mesoscale convective systems (MCSs) observed during the 1991 Cooperative Oklahoma Profiler Studies (COPS91) experiment are analyzed. Profiles of the vertical ...
Polarimetric Radar Rain Estimation through Retrieval of Drop Size Distribution Using a Bayesian Approach
Publisher: American Meteorological Society
Abstract: This study proposes a Bayesian approach to retrieve raindrop size distributions (DSDs) and to estimate rainfall rates from radar reflectivity in horizontal polarization ZH and differential reflectivity ZDR. With this ...
Rainfall Estimation with a Polarimetric Prototype of WSR-88D
Publisher: American Meteorological Society
Abstract: As part of the Joint Polarization Experiment (JPOLE), the National Severe Storms Laboratory conducted an operational demonstration of the polarimetric utility of the Norman, Oklahoma (KOUN), Weather Surveillance Radar-1988 ...
Rapid-Update Radar Observations of Downbursts Occurring within an Intense Multicell Thunderstorm on 14 June 2011
Publisher: American Meteorological Society
Abstract: n 14 June 2011, an intense multicell thunderstorm produced one nonsevere and three severe downbursts within 35 km of the rapid-update, S-band phased array radar (PAR) at the National Weather Radar Testbed in Norman, Oklahoma, ...
Effect of Precipitation Sampling Error on Flash Flood Monitoring and Prediction: Anticipating Operational Rapid-Update Polarimetric Weather Radars
Publisher: American Meteorological Society
A Polarimetric Analysis of Ice Microphysical Processes in Snow, Using Quasi-Vertical Profiles
Publisher: American Meteorological Society
Abstract: AbstractThis study implements a new quasi-vertical profile (QVP) methodology to investigate the microphysical evolution and significance of intriguing winter polarimetric signatures and their statistical correlations. QVPs ...
Radar Signatures Associated with Quasi-Linear Convective System Mesovortices
Publisher: American Meteorological Society
Electrical and Kinematic Structure of the Stratiform Precipitation Region Trailing an Oklahoma Squall Line
Publisher: American Meteorological Society
Abstract: An electric field sounding through the transition zone precipitation minimum that trailed an Oklahoma squall line on 18 June 1987 provides information about the electrical structure within a midlatitude trailing stratiform ...
