Comparison of Wind-Profiler and Radiosonde Measurements in the Tropics
Publisher: American Meteorological Society
Abstract: The performance and limitations of the Bureau of Meteorology Research Centre's (BMRC) 50-MHz wind profiler operating at Saipan in the central western Pacific are assessed. Hourly averaged profiler estimates of horizontal ...
Thermodynamic and Vertical Velocity Structure of Two Gust Fronts Observed with a Wind Profiler/RASS during MCTEX
Publisher: American Meteorological Society
Abstract: High-time-resolution wind profiler/RASS observations are used to describe the vertical velocity, temperature, and reflectivity fields of two gust fronts in detail. The first was a freely propagating gust front and the ...
Mesocyclone and Microburst Signature Distortion with Dual PRT Radars
Publisher: American Meteorological Society
Abstract: A simple model is used to illustrate the limitations of dual pulse repetition time (PRT) radars for measurements of wind fields with strong horizontal wind gradients. In such conditions, errors may occur even if the radial ...
The Organization of Convection in the Rainbands of Tropical Cyclone Laurence
Publisher: American Meteorological Society
Abstract: A slow-moving weak tropical cyclone passed near Darwin, Australia, in December 1990. Rainbands were observed by a Doppler weather radar and a 50-MHz wind profiler for over 24 h. The principal bands were seen to be organized ...
The Statistical Characteristics of Convective Cells in a Monsoon Regime (Darwin, Northern Australia)
Publisher: American Meteorological Society
Abstract: A season of operational cell and track data from Darwin, Australia, has been analyzed to explore the statistical characteristics of the convective cell heights. The statistics for the monsoon and break regimes are significantly ...
A Robust Error-Based Rain Estimation Method for Polarimetric Radar. Part II: Case Study
Publisher: American Meteorological Society
Abstract: ainfall estimation using polarimetric radar involves the combination of a number of estimators with differing error characteristics to optimize rainfall estimates at all rain rates. In Part I of this paper, a new technique ...
Evaluation of Microphysical Retrievals from Polarimetric Radar with Wind Profiler Data
Publisher: American Meteorological Society
Abstract: Polarimetric radar data have been used to produce microphysical classifications. This kind of analysis is run in a real-time mode from several research radars, including the C-band polarimetric (C-Pol) radar in Darwin, ...
An Examination of Wind Profiler Signal Processing Algorithms
Publisher: American Meteorological Society
Abstract: A numerical model to simulate radar data is used for testing various estimators of the Doppler shift in Doppler radar echoes. The estimators are the pulse pair and poly-pulse pair algorithms in the correlation domain, a ...
