<br />microphysical and dynamical data were collected by the Wyoming aircraft <br />and NCAR Doppler radar, respectively. Further evidence supports the <br />thought that the liquid exists in small quantities and is hard to find <br />in these mesoscale features while many ice crystals are present. <br /> <br />The major efforts during the 1982-83 field season included the start of the <br />SCPP-l experiment on cell u1 ar convect ion, the development of an effect ive <br />seeding strategy during SCPP-2 conditions (orographic, area-wide, embedded <br />bands), and gathering of further evidence as to where seeding potential <br />exists in Sierra' storms. Once again, mother nature provided one of the <br />heaviest precipitations recorded in the Sierra. The Central Sierra Snow <br />Laboratory, within the proj ect area, received 790 inches of snow (well over <br />80 inches of water equivalent). Nearly 50 percent of all potential seeding <br />opportun it ies were lost due to suspensions. The results of the seasons <br />activities can be summarized as follows: <br /> <br />1. When mother nature provides nearly 180 percent of normal precipita- <br />tion during the winter season, it is difficult to accomplish much <br />seeding research. The SCPP suspension criteri a are ilppropri ate for such <br />heavy precipitation episodes. For the first time in SCPP history all <br />seeding operations in March were suspended due to excess snow pack <br />conditions. <br /> <br />2. Randomized seeding operations in SCPP-1 conditions can be conducted <br />smoothly, especially since our cooperation with FAj~-ATC has improved. <br /> <br />3. Cloud physics aircraft can track a treated cloud when remaining at <br />the same flight altitude. The new approach for keeping the looking and <br /> <br />1-18 <br /> <br />~ <br /> <br />e <br /> <br />. <br /> <br />e <br />
