RISAn Expanded VVP Technique to Resolve Primary and Environmental Circulations in Hurricanes
Publisher: American Meteorological Society
Abstract: n expansion of the volume velocity processing (VVP) single-Doppler radar analysis method is presented for use with hurricanes. The so-called hurricane VVP (HVVP) method connects the estimated coefficients of a second-order ...
Principal Component Analysis of Doppler Radar Data. Part I: Geometric Connections between Eigenvectors and the Core Region of Atmospheric Vortices
Publisher: American Meteorological Society
Abstract: This is the first in a three-part series of papers that present the first applications of principal component analysis (PCA) to Doppler radar data. Although this novel approach has potential applications to many types of ...
Evidence for a Nimbostratus Uncinus in a Convectively Generated Mixed-Phase Stratiform Cloud Shield
Publisher: American Meteorological Society
Abstract: AbstractThe structure of a melting layer associated with a mesoconvective system is examined using a combination of in situ aircraft measurements and a unique Doppler radar operated by the U.S. Navy that has a range ...
Improving Short-Term Storm Predictions by Assimilating both Radar Radial-Wind and Reflectivity Observations
Publisher: American Meteorological Society
Abstract: A high-resolution data assimilation system is under development at the Naval Research Laboratory (NRL). The objective of this development is to assimilate high-resolution data, especially those from Doppler radars, into ...
Using Radar Wind Observations to Improve Mesoscale Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: A high-resolution radar data assimilation system is presented for high-resolution numerical weather prediction models. The system is under development at the Naval Research Laboratory for the Navy?s Coupled Ocean?Atmosphere ...
The Improvement to the Environmental Wind and Tropical Cyclone Circulation Retrievals with the Modified GBVTD (MGBVTD) Technique
Publisher: American Meteorological Society
Abstract: he ground-based velocity track display (GBVTD) was developed to deduce a three-dimensional primary circulation of landfalling tropical cyclones from single-Doppler radar data. However, the cross-beam component of the mean ...
Real-Time Implementation of Single-Doppler Radar Analysis Methods for Tropical Cyclones: Algorithm Improvements and Use with WSR-88D Display Data
Publisher: American Meteorological Society
Abstract: The NOAA/NWS/NCEP/Tropical Prediction Center/National Hurricane Center has sought techniques that use single-Doppler radar data to estimate the tropical cyclone wind field. A cooperative effort with NOAA/Atlantic Oceanographic ...
Radar Detection of Individual Raindrops
Publisher: American Meteorological Society
Abstract: Descriptions of the experimental design and research highlights obtained from a series of four multiagency field projects held near Cape Canaveral, Florida, are presented. The experiments featured a 3 MW, dual-polarization, ...
