with the manned observatories and use of the High

Plains radar, research studies would include precipi-

tation process modeling improvement and development

of synoptic analyses of mesoscale advection, vorticity,

vertical motion and atmospheric water balance to

improve opportunity recognition and broad-area eva1ua-

tion techniques. Increasing understanding of the

physical modification processes will lead to more

effective seeding techniques.

The physical evaluations will include analyses of

seeded and unseeded storm data on the timing and

intensity of precipitation, distribution of snowfall,

type and trajectories of snowflakes and changes in

cloud size and life span. The roles of ice crystal

riming and seeding imbedded convective clouds in

augmenting precipitation are actual remaining

physical uncertainties.
