<br />'I <br /> <br />I <br /> <br />Operationally. the 47 operational days for the 4-month season <br />was below the average of the previous 15 years---49.5 days. July <br />set a recordj it had the most seeding time of any July in the <br />previous 15 years. However, there was another July in which more <br />of the silver iodide seeding agent was dispensed than 1990, but <br />that was when there were no cloud base planes and the seeding <br />aircraft used only the cloud-top delivery method. <br /> <br />I <br /> <br />We had an almost average kind of year with most of our seeding <br />problems related to numbers of storms on operational days. This ls <br />a perennial problem, a problem that should be addressed at some <br />future point. There were some storm days in which there were mare <br />severe storms producing crop-damaging hail in our target area than <br />we were capable of effectively handling. Although there were many <br />major storms causing devastation from hail in our target area this <br />year, none of them were of the extremely large supercell variety of <br />storms wreaking the widespread damage that we have seen in other <br />years. <br /> <br />There appeared to be excellent cloud responses to our seeding <br />efforts aimed particularly at stimulating rainfall. The cloud <br />responses we saw often kept the cloud systems inside the target <br />area raining and persisting longer while surrounding areas did not <br />fare well at all. In general, moisture conditions ever the target <br />area this season was conducive to increased natural rainfall as the <br />"dry line" usually was well west into eastern or east-central <br />Colorado which meant more moisture available for eventual cloud <br />development in western Kansas. <br /> <br />21 <br />
