<br />entire evolution of the precipitation process within the cloud from initial <br /> <br />ice crystal formation, to the subsequent transport of precipitation embryos <br /> <br />through the cloud, and their development into precipitation-sized particles. <br /> <br />Determination of the relation between the concentration of ice embryos and <br /> <br />concentration of graupels is of particular importance, <br /> <br />~ <br /> <br />2. It is planned to test and refine procedures for real':"time convective <br /> <br />complex identification by radar. Ongoing analyses are developing criteria <br /> <br />for identifying convective complexes from radar data. The real-time applica- <br /> <br />tion of these criteria will be tested and r~fined, as needed, u~ing a new <br /> <br />color display of the radar PPI and "instant" color photography, The evolution <br /> <br />of radar echoes will be closely monitored so as to attempt to rapidly identify: <br /> <br />(1) newly formed convective complexes and (2) complE~xes that have evolved <br /> <br />into systems too large and complicated for continued treatment and/or sampling. <br /> <br />3. It is planned to test and refine procedures for the rapid identification <br /> <br />and treatment of towering cumulus and convective cotnplexes by the Learjet <br /> <br />seeding aircraft, and for fast turnaround when replenishing fuel and seeding <br /> <br />material. Included in the treatment tests will be determination of the <br /> <br />reliability of the dry ice dispenser. Identification will be based on a <br /> <br />combination of radar observations, laserfax satellite photos, and visual <br /> <br />recognition, although towering cumulus identification must often rely on <br /> <br />visual recognition alone, <br /> <br />Prompt treatment requires fast response after identification. Thus, <br /> <br />the seeding aircraft must be prepared for quick takE=off when a mission is <br /> <br />anticipated, and observing systems (visual, radar, and satellite) must be <br /> <br />monitored closely. Once a cloud system is chosen, the seeding aircraft will <br /> <br />1-6 <br />
