METHODOLOGY <br /> The focus of this task was to evaluate first echo detection using the KMBX radar and <br />comparing the time of first echo detection with the Stanley radar. The WSR-88D radars <br />have the ability to detect weak-echo features with its more sensitive receiver. The goal of <br />this task is to quantify the improvement in first echo detection along boundaries such as <br />outflows and fine lines using the more sensitive WSR-88D radar. All seeded days in the <br />summer of 1999 were examined in this study. <br /> This study compared the Stanley C-band radar with the KMBX S-band radar to <br />determine the time difference in first echo detection between the two radars. Only new <br />developing cells were selected for the study. The cells had to develop between the two <br />radars in the overlapping region within a maximum range of 150 km. For each day that <br />was seeded, the radar display was examined and all new cells were determined. All new <br />echo development between the radars was detected by examining the radar images. When <br />a case was found, the time that each radar first detected the development was recorded. <br />Once all new echo development cases were discovered, a mean time difference between the <br />two radars was calculated. <br /> In the analysis process, Stanley radar data were examined first. For each new cell <br />detected, the time was recorded. After all the new cell development cases were detected <br />using the Stanley radar, each case was examined with the KMBX radar. The time that the <br />cells where first detectable from the KMBX radar was also recorded. Then the rest of the <br />KMBX radar data was examined to see if there were any cases were the KMBX radar <br />detected a storm and the Stanley radar did not. Overall, there were 52 cases of new cell <br />development out of the 24 days used in this study between the two radars. <br />12 <br />
