RISUsing CASA IP1 to Diagnose Kinematic and Microphysical Interactions in a Convective Storm
Publisher: American Meteorological Society
Abstract: Data from the Collaborative Adaptive Sensing of the Atmosphere (CASA) Integrated Project I (IP1) network of polarimetric X-band radars are used to observe a convective storm. A fuzzy logic hydrometeor identification algorithm ...
A Theory-Based Hydrometeor Identification Algorithm for X-Band Polarimetric Radars
Publisher: American Meteorological Society
Abstract: Although much work has been done at S band to automatically identify hydrometeors by using polarimetric radar, several challenges are presented when adapting such algorithms to X band. At X band, attenuation and non-Rayleigh ...
An Integrated Display and Analysis Methodology for Multivariable Radar Data
Publisher: American Meteorological Society
Abstract: Polarimetric Doppler radars provide valuable information about the kinematic and microphysical structure of storms. However, in-depth analysis using radar products, such as Doppler-derived wind vectors and hydrometeor ...
Drop Size Distributions and Radar Observations of Convective and Stratiform Rain over the Equatorial Indian and West Pacific Oceans
Publisher: American Meteorological Society
Abstract: wo-dimensional video disdrometer (2DVD) data were analyzed from two equatorial Indian (Gan) and west Pacific Ocean (Manus) islands where precipitation is primarily organized by the intertropical convergence zone and the ...
Observations of the 14 July 2011 Fort Collins Hailstorm: Implications for WSR-88D-Based Hail Detection and Warnings
Publisher: American Meteorological Society
Abstract: he issuance of timely warnings for the occurrence of severe-class hail (hailstone diameters of 2.5 cm or larger) remains an ongoing challenge for operational forecasters. This study examines the application of two remotely ...
A Robust C-Band Hydrometeor Identification Algorithm and Application to a Long-Term Polarimetric Radar Dataset
Publisher: American Meteorological Society
Abstract: new 10-category, polarimetric-based hydrometeor identification algorithm (HID) for C band is developed from theoretical scattering simulations including wet snow, hail, and big drops/melting hail. The HID is applied to ...
Comparison of Single- and Dual-Polarization–Based Rainfall Estimates Using NEXRAD Data for the NASA Iowa Flood Studies Project
Publisher: American Meteorological Society
Abstract: his study compares and evaluates single-polarization (SP)- and dual-polarization (DP)-based radar-rainfall (RR) estimates using NEXRAD data acquired during Iowa Flood Studies (IFloodS), a NASA GPM ground validation field ...
A Dual-Polarization Radar Hydrometeor Classification Algorithm for Winter Precipitation
Publisher: American Meteorological Society
Abstract: he purpose of this study is to demonstrate the use of polarimetric observations in a radar-based winter hydrometeor classification algorithm. This is accomplished by deriving bulk electromagnetic scattering properties of ...
Lightning in Wildfire Smoke Plumes Observed in Colorado during Summer 2012
Publisher: American Meteorological Society
Abstract: yrocumulus clouds above three Colorado wildfires (Hewlett Gulch, High Park, and Waldo Canyon; all during the summer of 2012) electrified and produced localized intracloud discharges whenever the smoke plumes grew above 10 ...
Dual-Polarization Radar Rainfall Estimation over Tropical Oceans
Publisher: American Meteorological Society
Abstract: AbstractDual-polarization radar rainfall estimation relationships have been extensively tested in continental and subtropical coastal rain regimes, with little testing over tropical oceans where the majority of rain on ...
