Spectrum Width Measured by WSR-88D: Error Sources and Statistics of Various Weather Phenomena

From: Journal of Atmospheric and Oceanic Technology | Date: June 1, 2004| Author: | Copyright information

ABSTRACT

Spectrum widths, one of the three moments measured and displayed by the Weather Surveillance Radar-1988 Doppler (WSR-88D), are categorized for various weather conditions showing both expected and unexpected results. Weather phenomena are classified into seven categories based on radar observations, and the statistics of the censored spectrum width fields for each of the categories are obtained. Daytime fair weather without birds, stratiform rain and snow, and isolated tornadic storms produce weather signals that have the smallest volumetric median values of spectrum widths (i.e., ...
