<br />-. <br /> <br />To the extent that the Adamsville rawinsonde winds represent the <br />. " <br /> <br />flow toward the research area they suggest whether transport of seeding <br /> <br />.. <br /> <br />material was likely or unlikely from the Washington County area to the <br /> <br />research area near Beaver. During several of the STORMS (Nos. 2, 3-, 5, <br /> <br />9, 11 and 13) but prior to seeding winds were directed to some degree <br /> <br />-- <br /> <br />from Washington County toward the research area. But since there was no <br /> <br />seeding during these times there was no transport of material into the <br /> <br />clouds being studied. By the time seeding commenced during these STORMS <br /> <br />. <br /> <br />winds had in most cases veered to a northerly direction and were <br /> <br />opposing transport of seeding material to the research area. <br /> <br />In the <br /> <br />other STORMS (Nos. 6, 7 and 18) winds were from a westerly or northerly <br /> <br />. <br /> <br />direction both before and during seeding. <br /> <br />The transport of seeding <br /> <br />m.aterial to the research area during these STORMS was unlikely. Seeding <br /> <br />in the research area may have occurred during part of STORM 13. Up to <br /> <br />. <br /> <br />0500 MST on 3 March winds had a significant southerly component and <br /> <br />speeds were <br /> <br />5-15 m s -l . <br /> <br />Approximately 2 to 6 hr would have been <br /> <br />required for seeding material to traverse the approximate ly 100 km <br /> <br />. <br /> <br />distance between the generators and the research area. <br /> <br />Transport of <br /> <br />seeding material to the research area cannot be excluded in this case. <br /> <br />It is not known whether there were any seeding effects. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />-22- <br />
