Rainfall and Hail Damage Reports <br /> <br />There was no organized effort on the part of Muddy <br />Road V field team to collect precipitation data. Programs are <br />presently underway in the Kansas Water Resources Board to compile <br />precipitation data through their voluntary raingage observer network <br />and the local crop hail insurance companies. <br /> <br />c. Muddy Road V Operations Summaries <br />1. Monthly Summary <br /> <br />Month to month variation in seeding activity is of <br />interest to planners in the allocation of resources ,for future seasons. <br />Table 1 shows the monthly variation in activity for the 1979 season. <br />The frequency of "rain augmentation only" days was <br />at a maximum in May, with the frequency of severe hail storms <br />being less than normal for late spring. In late June and July storms <br />were usually intense and required hail suppression treatment. Hail <br />suppression seeding was usually followed by seeding for rain augmen- <br />tation. For this reason and because there is evidence that storms <br />seeded for hail suppression causes precipitation (radar echoes) to <br />expand in area and'duration, hail suppression days were also classi- <br />fied as rain augmentation days. <br />More extensive study of storm behavior can be made <br />by use of Muddy Road data in conjunction with data collected from <br />other sources. For example, comparison of the physical character- <br />istics and the precipitation from seeded and non-seeded storms can <br />be made when raingage and crop hail data become available. <br /> <br />13 <br />
