Use of Wind-Shear Displays for Doppler Radar Data

The usefulness of displaying vertical wind shear on a radar range height indicator is demonstrated. Fine structure in the pattern of shear is shown to be helpful for inferring general flow patterns and the occurrence of billows due to shearing (Kelvin–Helmholtz) instability. Corresponding author address: Prof. Keith A. Browning, Joint Centre for Mesoscale Meteorology, Department of Meteorology,...

Nonlinear Retrieval of Single Doppler Radar Wind Field Using Wavelet

In this paper, we develop a novel approach to nonlinearly retrieving wind field from radial wind data, which are obtained by Single Doppler radar. In general, it is impossible to uniquely recover the 2-D (or 3D) wind field from single Doppler radar, since the problem is underdetermined. In order to overcome the difficulty, according to the characteristic of the wind field distribution, we add t...

Wind observations with Doppler weather radar

Introduction Weather radars are commonly employed for detection and ranging of precipitation, but radars with Doppler capability can also provide detailed information on the wind associated with (severe) weather phenomena. The Royal Netherlands Meteorological Institute (KNMI) operates two identical C-band (5.6 Ghz) Doppler weather radars. One radar is located in De Bilt and the other one is loc...

Wind velocity observation with a CW Doppler radar

We study the problem of gathering information about wind velocity from continuous-wave clear-air Doppler radar measurements. The radar is assumed to be a monostatic fixed-frequency Doppler radar, and the wind velocity as well as the reflectivity are modeled as random fields with statistical parameters depending on the altitude. We seek to reconstruct the hodograph curve of the wind profile, i.e...

Variational Pseudo-Multiple-Doppler Wind Retrieval in the Vertical Plane for Ground-Based Mobile Radar Data

A variational procedure is developed that utilizes mobile ground-based range–height indicator (RHI) Doppler radar velocity data for the synthesis of two-dimensional, RHI plane wind vectors. The radial component winds are obtained with the radar platform in motion, a data collection strategy referred to as the rolling RHI technique. Using the assumption of stationarity—standard to any pseudo-mul...
