<br />on067t:: <br /> <br />SCIENTIFIC OBJECTIVE <br />1. Tasks - (a) Cumulus - Measure and analyze 1,000 to <br />1,500 cumulus clouds singly or in groups, <br />including unseeded and ice-phase or hygro- <br />scopic seeded and possibly other affected <br />clouds, and detail the important physical <br />and dynamic processes and precipitation <br />mechanisms. Incorporate findings into <br />improved models and verify models on an <br />independent data set. Define the measurable <br />parameters describing favorable conditions <br />or "windows" for cloud seeding. Develop a <br />thorough precipitation modification potential <br />estimate and climatological probabilities. <br />Perform analyses on the sources, probabilities, <br />degree, and relative importance of remaining <br />uncertainties. Formulate modeling concepts <br />and techniques for optimum precipitation <br />management of all cumulus clouds. <br /> <br />(b) Upslope, Winter, Frontal, and Cyclonic - <br />Depending on resources, measure, infrequently <br />treat, and analyze some 20 to 50 weather <br />systems of each type and develop preliminary <br />modification hypotheses and potential aug- <br />mentation estimates for these situations. <br />7 <br />
