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 ...
The Relationship between Precipitation and Lightning in Tropical Island Convection: A C-Band Polarimetric Radar Study
Publisher: American Meteorological Society
Abstract: One of the primary scientific objectives of the Maritime Continent Thunderstorm Experiment was to study cloud electrification processes in tropical island convection, in particular, the coupling between ice phase precipitation ...
The Development and Structure of an Oceanic Squall-Line System during the South China Sea Monsoon Experiment
Publisher: American Meteorological Society
Abstract: A primary goal of the South China Sea Monsoon Experiment (SCSMEX), a major field campaign of the Tropical Rainfall Measuring Mission (TRMM), is to define the initiation, structure, evolution, and dynamics of precipitation ...
Environmental Control of Cloud-to-Ground Lightning Polarity in Severe Storms
Publisher: American Meteorological Society
Abstract: In this study, it is hypothesized that the mesoscale environment can indirectly control the cloud-to-ground (CG) lightning polarity of severe storms by directly affecting their structural, dynamical, and microphysical ...
Evolution, Structure, Cloud Microphysical, and Surface Rainfall Processes of Monsoon Convection during the South China Sea Monsoon Experiment
Publisher: American Meteorological Society
Abstract: A two-dimensional cloud-resolving simulation is combined with dual-Doppler and polarimetric radar analysis to study the evolution, dynamic structure, cloud microphysics, and rainfall processes of monsoon convection observed ...
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 ...
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 ...
Total Lightning Signatures of Thunderstorm Intensity over North Texas. Part I: Supercells
Publisher: American Meteorological Society
Abstract: It is shown that total lightning mapping, along with radar and National Lightning Detection Network (NLDN) cloud-to-ground lightning data, can be used to diagnose the severity of a thunderstorm. Analysis of supercells, ...
On the Correction of Partial Beam Blockage in Polarimetric Radar Data
Publisher: American Meteorological Society
Abstract: Three methodologies for correcting the radar reflectivity factor (ZH) in the presence of partial beam blockage are implemented, compared, and evaluated using a polarimetric radar dataset from the North American Monsoon ...
A Comparison of Two Ground-Based Lightning Detection Networks against the Satellite-Based Lightning Imaging Sensor (LIS)
Publisher: American Meteorological Society
Abstract: ightning stroke data from both the World Wide Lightning Location Network (WWLLN) and the Earth Networks Total Lightning Network (ENTLN) were compared to lightning group data from the Lightning Imaging Sensor (LIS) from 1 ...
