However, for the individual episodes <br />the SLW averages showed a wide range from .018 to .170 mm <br />per hour with four of them averaging over .10 rom per hour. <br /> <br />The only B-2 storm type episode had relatively good SLW <br />for five hours (.102 rom per hour) but produced no precipitation <br />at any of the network gauge sites. There were no episodes <br />which appeared to fit the Medina B-1 synoptic pattern and <br />the MC-3 episode was not classified with a Medina storm type. <br /> <br />When the hourly average of SLW was at least .01 mm it <br />averaged .095 mm for all 16 of the episodes with the median <br />value between .095-.096 mm. SLW averaged over all the hours <br />of all the episodes was slightly less, .077 mm per hour, with <br />the median between .070 and .075 mm. The highest episode <br />average was .197 mm per hour (for SS-l) and the least was <br />.002 rom per hour (for SS-10). <br /> <br />The relatively good SLW averages and the fact that several <br />of the A-2 type storms (and the B-2 storm) produced little <br />or no precipitation would suggest there is some potential <br />for augmentation by cloud seeding. In addition, the fact <br />that the average SLW for the A-1 type storms were greater <br />than the other types in three out of four of the cases would <br />suggest that the potential for augmentation with this type <br />might be greater than originally thought. <br /> <br />3-16 <br />
