<br />2. Is there a significant difference in storm frequency and <br />structure from one subbasin to another? <br /> <br />3. Is there a difference in seedability from north to south over <br />the Basin? <br /> <br />.. <br /> <br />Calibration seeding trials will be conducted to accommodate local <br />meteorological and topographic influences on the transferability of <br />operational seeding techniques. <br /> <br />Ground-Based Seedin~ Studies. The Basinwide possibilities of <br />ground-based seeding deserve careful scientific investigation due <br />to the distinct economic advantage offered by this seeding mode if <br />the targeting problems experienced in previous programs could be <br />solved. The transport and diffusion studies necessary to assess <br />the feasibility of ground-based seeding will be conducted in a <br />subbasin other than the San Juan to avoid contamination of San <br />Juan operations. In these studies, plume dispersion and transport <br />will be examined during the evolution of storms to determine: <br /> <br />1. When and where the seeding material is lifted into the cloud. <br /> <br />2. If dispersion is adequate to deliver required concentrations <br />of seeding material. <br /> <br />3. If persistence is a significant problem in the target and <br />beyond. <br /> <br />The answers to these questions plus improved opportunity recognition <br />and determination of favored areas for initiation of convection <br />will determine the feasibility of an effective, remote-controlled <br />ground-based seeding delivery system. The additional cost of this <br />optional ground-based seeding optimization effort is estimated to <br />be $5.6 million over a 6-year period. <br /> <br />V-9 <br />
