RISEstimation of Rainfall Drop Size Distributions from Dual-Frequency Wind Profiler Spectra Using Deconvolution and a Nonlinear Least Squares Fitting Technique
Publisher: American Meteorological Society
Abstract: This paper compares two different analysis approaches for dual-frequency (VHF and UHF) wind profiler precipitation retrievals. The first technique is based on a general deconvolution process to remove broadening effects ...
A Comparison of VHF Wind Profiler Observations and the NCEP–NCAR Reanalysis over the Tropical Pacific
Publisher: American Meteorological Society
Abstract: VHF wind profiler measurements of zonal and meridional winds are compared with the NCEP?NCAR reanalysis at sites in the tropical Pacific. By December 1999 the profilers at Darwin, Australia, and Biak, Indonesia, in the ...
Improving Wind Profiler–Measured Winds Using Coplanar Spectral Averaging
Publisher: American Meteorological Society
Abstract: A method is presented that increases the detectability of weak clear-air signals by averaging Doppler spectra from coplanar wind profiler beams. The method, called coplanar spectral averaging (CSA), is applied to both ...
Wind Profiler Observations over the Central Equatorial Pacific: Optimizing Processing to Improve Quality and Height Coverage
Publisher: American Meteorological Society
Abstract: UHF (boundary layer) and VHF (troposphere?stratosphere) wind profilers have operated at Christmas Island (2°N, 157°W) in the central equatorial Pacific from 1986 to 2002. Observed profiles of winds are sparse over the ...
Boundary Layer Development over a Tropical Island during the Maritime Continent Thunderstorm Experiment
Publisher: American Meteorological Society
Abstract: Data collected during the Maritime Continent Thunderstorm Experiment (MCTEX) (10 November?10 December 1995) have been used to analyze boundary layer development and circulations over two almost flat, tropical islands. The ...
