might ascend high enough to produce a seeding increment. With convection, the plume was carried aloft into stronger ~inds, and the maximu~ seeding increment occurred slightly wes~ of King's Peak, with smaller increments predicted southwest of t;~ere to near Heber. Moving the seeding source 20 km downwind of Heber, where ~he elevation would be 1800 it higher, had a ~egative effect on the rnaxi~um seeding increment, which decreased to almost zero from the 0.2 mmjhr increment from seeding near Heber. In addition, blowover of effects into Wyo~ing was also noted. Aerial seeding along Victor Airway 484 near Heber resulted in good seeding increments in the Uinta ~ountains. However, the high minimum altitude requirements in this region could prevent seeding when the temperature a 1: the seed i ng 1 evel was 1:00 cold. In t he case used in the ~odel, the temperature at seeding level was -150C. Seeding at temperatures much colder than that would probably result in smaller seeding incre~ents. A~other simulation was made for northwesterly flow over ~he Uinta Mountains. Seeding from near Kemmerer, Wyoming ~nder stable flow resulted in a good increment at King's Peak. T~e width of the Uinta Mountains and the relatively large distance upwind to the seeding site probably explain the good results under stable conditions. When the seeding site was mo~ed 40 k~ downwind (near Leroy, Wyoming), the seeding increment was decreased substantially compared to the previous run and blowover of marginal seeding increments to the Uinta Basin occ~rred. With convection, seeding from near Kemmerer prod;Jced a gOOQ incre~ent in the north-facing slopes of the Uinta ~oun- ~ains. Again, ~oving tee seerling site to near Leroy dec~eased -:::e i~ cremen t. Considering the results under convective conditions in "real world.' ter'!!s would probably change the value and lOC9.tion of -:ie seeding increment, since "real world" ronvective 5-35
