Nonlinear Wind Analysis of Single-Doppler Radar Observations within a DVAD Framework
Publisher: American Meteorological Society
Abstract: he application of the distance velocity azimuth display (DVAD) method to the retrieval of vertical wind profiles from single-Doppler radar observations is presented in this study. It was shown that Doppler velocity ...
A Squall-Line-Like Principal Rainband in Typhoon Hagupit (2008) Observed by Airborne Doppler Radar
Publisher: American Meteorological Society
Abstract: his study examines the structure and dynamics of Typhoon Hagupit?s (2008) principal rainband using airborne radar and dropsonde observations. The convection in Hagupit?s principal rainband was organized into a well-defined ...
Subrainband Structure and Dynamic Characteristics in the Principal Rainband of Typhoon Hagupit (2008)
Publisher: American Meteorological Society
Abstract: AbstractThe principal rainband in tropical cyclones is currently depicted as a solitary and continuous precipitation region. However, the airborne radar observations of the principal rainband in Typhoon Hagupit (2008) ...
Distance Velocity–Azimuth Display (DVAD)—New Interpretation and Analysis of Doppler Velocity
Publisher: American Meteorological Society
Abstract: he concept and mathematical framework of the distance velocity?azimuth display (DVAD) methodology is presented. DVAD uses rVd (Doppler velocity scaled by the distance from the radar to a gate, r) as the basis to display, ...
Design Strategies of an Hourly Update 3DVAR Data Assimilation System for Improved Convective Forecasting
Publisher: American Meteorological Society
Abstract: his study examines two strategies for improving the analysis of an hourly update three-dimensional variational data assimilation (3DVAR) system and the subsequent quantitative precipitation forecast (QPF). The first strategy ...
A Generalized Navigation Correction Method for Airborne Doppler Radar Data
Publisher: American Meteorological Society
Abstract: AbstractUncertainties in aircraft inertial navigation system and radar-pointing angles can have a large impact on the accuracy of airborne dual-Doppler analyses. The Testud et al. (THL) method has been routinely applied ...
