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...
متن کاملWind 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...
متن کاملNonlinear 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...
متن کاملUse 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,...
متن کامل8.1 Development of a Climatology of Vertically Complete Wind Profiles from Doppler Radar Wind Profiler Systems
Space vehicle loads and trajectory assessments utilize archives of both discrete and sequential wind profiles to ensure robust structural integrity during vehicle design. Historically, vehicle programs have used balloonbased measurements, which have three primary limitations inherent to balloon systems. First, the high cost of balloon releases makes high-frequency balloon sampling impractical, ...
