<br />.~ <br /> <br />4. The hypothesis in use in Utah for the operational program continues <br /> <br />to appear reasonable and the present state/federal research plan <br /> <br />continues to be appropriate for evaluating the respective components <br /> <br />of the hypothesis. This appears particularly true for the 60-70% <br /> <br />of the precipitation producing clouds that are neutral or stably <br /> <br />stratified. A different and more complex hypotheses than used for <br /> <br />thesl~ blanket orographic clouds is needed for the convective cloud <br /> <br />systems that produced some 30% of the precipitation during the 1983 <br /> <br />field program. <br /> <br />Several conclusions relating to the research program also appear <br /> <br />justified. <br />1. An excellent data set was obtained during the 1983 field program. <br /> <br />., <br /> <br />2. The greatest deficiency in obsl~rvational data involved the absence <br /> <br />of Co-band and aircraft data for the blanket orographic cloud systems <br /> <br />that produced nearly half of the precipitation during the field <br /> <br />program. <br /> <br />~ <br /> <br />!! <br /> <br />3. Careful analysis and interpretation of presently available data <br /> <br />for each of the types of identified Tushar Mountain cloud systems <br /> <br />can provide good first order estimates, of their <br /> <br />liqu:id water content and valuable input for planning future field <br /> <br />research programs. <br /> <br />4. Serious consideration needs to be directed toward hypothesis development <br /> <br />for a hypothesis that applies to convective cloud systems. <br /> <br />5. The operating site for the C-band radar needs to be reevaluated. A <br /> <br />site closer to the Tushars that would lower the elevation angles for <br /> <br />,; <br /> <br />iv <br />
