CSU-CHILL Casebook: 25 June, 2005
During the afternoon hours of 25 June 2005, a group of thunderstorms developed in the southeast azimuth quadrant of the CSU-CHILL radar. The leading edge of the low level outflow from these storms produced a gust front that propagated into the boundary layer airmass ahead of the storms. Insects were fairly evenly distributed within the undisturbed regions of the boundary layer. The insect concentrations were enhanced due to the convergent sir motions along the guts front.
Four sweep COMET surveillance PPI scans were done while an area of thunderstorms developed near Prospect Valley. One echo core showed the low level development and dissipation of ZDR hail signatures. Phidp variations also showed significant time variations in the approx 4 minute time resolution data.
