I updrafts and downdrafts occur in discrete locations rather ttan the averaged conditi8ns in the model. That is, seeding nea~ Kemmerer-might not be as s~ccessful as the model indicates. An actual convec~ive ele~ent near the seeding site could entrain ~he seeding ffia~erial and resul~ in seeding effects much nearer Kem~erer than ~odeled. Aerial seeding on Victor Airway 6 ha~fway between Kemnerer and Leroy resul~ed in a very goon seeding ef:ec~ along t~e north-facing slopes 0: the Uinta ~.~oun tains. The third sim~lation for the Uinta V.ountains was seeding ato~ the ~est Tavaputs Pla~eau wit~ south-southwesterly flow. This mode~ing study was actua.lly a variation of seeding studies for the nnta Basin (see Section 5.2.7) and was s~own in Fig. 5.4. The seeding location would require a remotely-controlled seeding unit. Seedi~g under stable flow resulted in only a slight increnen"t in the uinta ~lountains. However, seeding in a more convective environmen"t gave a good seeding increMent to the south-facing slopes of ~he Uinta ~ountains. No modeling studies were conducted for the Wasatch Range. It was felt that the seeding design used for the portions of the Wasatch Plateau in the South Central Division could be transferred northward to the Northern Mountains Division. The saggesteC design for standby seeding operations in ~his division invo~ves a network of 35 ground-based seeding uni~s, ~ost of whi~~ would he located in the high valleys of the Wasatcn Range (see Figure 5.10). Other seeding units would be locatec in Sout:hwesterrr Wyoming to a!fect the Uinta Uountai~s under northwesterly flow. ~wo remotely controlled see'jing un:.ts in "the \~est. TaVap\lts Plateau are als() recommended. The units :ocated within the Wasatc~ Range w'::>:.Ild be used for 5-36
