Multiple Doppler Radar Analysis for Retrieving the Three-Dimensional Wind Field Within Thunderstorms
نویسنده
چکیده
Multiple Doppler radar analysis has been widely used to retrieve three-dimensional wind fields within thunderstorms and meso-scale convective systems (MCS) since the late 1960s. A number of countries have constructed dense operational radar networks, such as the Operational Programme for the Exchange of Weather Radar Information (OPERA; Köck et al., 2000), to monitor and forecast severe weather in metropolitan regions. Multiple Doppler radar analysis using such operational radar networks improves 1) understanding of the physical mechanisms behind heavy rainfall and severe wind, 2) detection and forecasting of hazardous weather phenomena, and 3) planning for mitigation of human and socioeconomic losses in metropolitan regions.

The advantages of using Doppler weather radar to track and forecast mesoscale severe weather events are widely known to both meteorologists and the public. With the use of Doppler radar, meteorologists can provide better information to the public, ultimately saving lives and property, by remotely observing the internal structure of thunderstorms at high resolution. Despite its highly advanced c...
متن کاملA three-dimensional variational single-Doppler velocity retrieval method with simple conservation equation constraint
In this paper, a new three-dimensional variational analysis scheme capable of retrieving three-dimensional winds from single Doppler observations of convective storms is developed. The method incorporates, in a single cost function, Doppler radar observations, a background field, smoothness and mass continuity constraints, and the residual of reflectivity or radial velocity conservation. By min...

■ Weather phenomena such as microburst wind shear and severe thunderstorms are major concerns to the aviation industry. A number of significant airplane accidents have resulted from wind-shear encounters during takeoff and landing, and thunderstorms are a major contributor to airplane delay. Providing fully automated and timely warnings of these phenomena by radar is challenging because it requ...
متن کاملRetrieving Three Dimensional Displacements of InSAR Through Regularized Least Squares Variance Component Estimation
Measuring the 3D displacement fields provide essential information regarding the Earth crust interaction and the mantle rheology. The interferometric synthetic aperture radar (InSAR) has an appropriate capability in revealing the displacements of the Earth’s crust. Although, it measures the real 3D displacements in the line of sight (LOS) direction. The 3D displacement vectors can be retrieved ...
متن کاملA Multiple-Doppler Synthesis and Continuity Adjustment Technique (MUSCAT) to Recover Wind Components from Doppler Radar Measurements
A new approach is presented to account for a simultaneous solution of the three wind components from at least a pair of Doppler radar observations, which could remove potential drawbacks of an iterative (nonsimultaneous) solution of Cartesian dual-Doppler analysis techniques. The multiple-Doppler synthesis and continuity adjustment technique (MUSCAT) is derived from the extended overdetermined ...
