Abstract
Delivery of nucleating materials to cloud systems from individual ground generators can play an important role in the beneficial modification of orographic cloud systems. Substantial evidence from the Colorado State University mountain study at Climax is presented to show that ground-released seeding materials do under some weather situations in fact enter the mountain cloud systems and produce changes in the precipitation. Evidence is also presented to show that under other weather situations seeding materials are not carried to the proper clouds at a place and time to be of value. A discussion of atmospheric transport mechanisms is presented to serve as a basis for understanding the motions of seeding materials once released from a ground source. The approaches, or directions, for further research are discussed. This includes consideration of the coagulation problem in the vicinity of the generator site. The use of wind tunnel modeling, which can provide basic information and specific results for specific areas, is emphasized.
