RESULTS <br /> This section shows the results of the comparison between Stanley and the KMBX <br />radar. Table 2 shows the date and a summary of time difference between the radar for <br />first echo detection. It can be seen that there were time differences that were negative. <br />This indicates that the Stanley radar detected the new cell development first. However, <br />the time differences were less than three minutes. Therefore, they were considered to <br />have occurred at the same time as the KMBX radar. This was due to the fact that the two <br />radars have independent scan schedules with average of six minutes between scans. In <br />our study, we assumed that any time less the four minutes occurred at during the same <br />scan. <br /> The average, minimum, and maximum time difference between the two radars were <br />calculated. The average time difference between the two radars was eight minutes, This <br />means that, on average, the KMBX radar detects first echo detection a scan sooner than <br />the Stanley radar. Again, a difference of eight minutes was near the six minute scan <br />sequence. Therefore, it was considered to be a difference of one scan. The maximum <br />time difference calculated in this study was 42 minutes. This large time difference was <br />mainly due to attenuation of the Stanley radar. In this case, there was a line of storms <br />tracking over the Stanley radar, when a new cell developed to the southeast of the radar. <br />The attenuation due to the storms moving over the radar caused the new cell development <br />not to be detected by the Stanley radar until the storms were clear of the radar and the <br />impact of attenuated was reduced. <br /> The time difference between the radars is shown in Figure 2, a box plot of the <br />difference in minutes. The box plot indicates that the mean time difference of first echo <br />14 <br />
