A dual-Doppler analysis of a narrow cold frontal rainband in central Pennsylvania
A411 (Georgia World Congress Center)
Two Doppler On Wheels (DOW) radars were deployed near the campus of Pennsylvania State University to observe the passage of a narrow cold frontal rainband on 2 November 2004. The data collection and analysis were undertaken by students in a special radar meteorology class held in conjunction with the Pennsylvania Area Mobile Radar Experiment (PAMREX). Wind syntheses were produced from the dual-Doppler observations at 3-minute intervals during a period spanning approximately 1 hour. The paper discusses the fine-scale reflectivity, vertical velocity, and vertical vorticity fields associated with the rainband. Comparisons of the high-resolution DOW data and WSR-88D data also are made, as are comparisons of the observed rainband structure to previous conceptual models of frontal rainbands.
