RISSensitivity of C-Band Polarimetric Radar–Based Drop Size Estimates to Maximum Diameter
Publisher: American Meteorological Society
Abstract: stimating raindrop size has been a long-standing objective of polarimetric radar?based precipitation retrieval methods. The relationship between the differential reflectivity Zdr and the median volume diameter D0 is typically ...
Vertical Radar Reflectivity Structure and Cloud-to-Ground Lightning in the Stratiform Region of MCSs: Further Evidence for In Situ Charging in the Stratiform Region
Publisher: American Meteorological Society
Abstract: This study presents further evidence in support of an in situ, noninductive charging mechanism as the process likely responsible for significant electrification of the trailing stratiform regions of mesoscale convective ...
A Novel Approach to Identify Sources of Errors in IMERG for GPM Ground Validation
Publisher: American Meteorological Society
Abstract: he comparison of satellite and high-quality, ground-based estimates of precipitation is an important means to assess the confidence in satellite-based algorithms and to provide a benchmark for their continued development ...
Incorporating Ice Crystal Scattering Databases in the Simulation of Millimeter-Wavelength Radar Reflectivity
Publisher: American Meteorological Society
Abstract: The Canadian CloudSat/Cloud?Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Validation Project (C3VP) was designed to acquire aircraft, surface, and satellite observations of particle size distributions ...
Electrically Active Hot Towers in African Easterly Waves prior to Tropical Cyclogenesis
Publisher: American Meteorological Society
Abstract: It has been hypothesized that intense convective-scale ?hot? towers play a role in tropical cyclogenesis via dynamic and thermodynamic feedbacks on the larger-scale circulation. In this study the authors investigate the ...
Regional Variability in Tropical Convection: Observations from TRMM
Publisher: American Meteorological Society
Abstract: Observation of the vertical profile of precipitation over the global Tropics is a key objective of the Tropical Rainfall Measuring Mission (TRMM) because this information is central to obtaining vertical profiles of latent ...
Preliminary Development and Evaluation of Lightning Jump Algorithms for the Real-Time Detection of Severe Weather
Publisher: American Meteorological Society
Abstract: Previous studies have demonstrated that rapid increases in total lightning activity (intracloud + cloud-to-ground) are often observed tens of minutes in advance of the occurrence of severe weather at the ground. These rapid ...
A Climatology of Disdrometer Measurements of Rainfall in Finland over Five Years with Implications for Global Radar Observations
Publisher: American Meteorological Society
Abstract: o improve the understanding of high-latitude rain microphysics and its implications for the remote sensing of rainfall by ground-based and spaceborne radars, raindrop size measurements have been analyzed that were collected ...
Cloud-to-Ground Lightning Observations from TOGA COARE: Selected Results and Lightning Location Algorithms
Publisher: American Meteorological Society
Abstract: Recently, observations of electrified oceanic convection and associated cloud-to-ground (CG) lightning were obtained over the tropical western Pacific Ocean during TOGA COARE (Tropical Ocean Global Atmosphere Coupled ...
The Relationship between Severe Storm Reports and Cloud-to-Ground Lightning Polarity in the Contiguous United States from 1989 to 1998
Publisher: American Meteorological Society
Abstract: The majority (61%) of severe storm reports (i.e., large hail and tornado) during the 1989?98 warm seasons (April?September) were associated with predominantly (>90%) negative cloud-to-ground (PNCG) lightning. Across the ...
