<br />The contractor is perf rming cloud physics research and experimental preclpl- <br />tat ion enhancement inv stigations in connection with HIPLEX, the CRBP, <br />and the SCPP. Studies for the SCPP and the Colorado River are discussed in <br />their respective secti ns of this report. <br /> <br />The university continu d cloud studies and analyses leading to a design of <br />the HIPLEX-1 experimen , including: developing climatologies of the relevant <br />cloud parameters (such as liquid water ice crystal concentrations), examining <br />trial seeding results, and refining aircraft coordination procedures. Special <br />studies of the melting zone revealed that rainfall estimation measurements <br />needed to be made at t e +10 oc level. The flight pattern and numerical <br />technique for estimati g rainfall from an aircraft were then designed. <br /> <br />These studies and anal ses were used to complete. the HIPLEX-1 experiment. <br />They are published in liThe Design of HIPLEX-1.11 <br /> <br />The experiment was ini iated and 12 official clouds were treated and studied. <br />With those 12 clouds alone, the response variables measuring early development <br />of snow conclusively sowed, both physically and statistically, that clouds <br />seeded with dry ice ha e much higher concentrations of snow than natural <br />clouds. Response variables measuring precipitation later in the lifetimes of <br />the clouds are not yet statistically significant and will need to be gathered <br />from more clouds in fu ure years. <br /> <br />Convective complexes, simple thundershowers to large squall lines, also were <br />examined in preparatio for the experiment following completion of HIPLEX-1. <br /> <br />The UW King Air cloud physics aircraft, a state-of-the-art atmospheric <br />physics laboratory developed especially for Project Skywater research, <br />conducted tests of the seeded clouds. The airplane is equipped with a full <br />complement of weather- onitoring instruments and an onboard computer system <br />to direct data collection and display. In addition, a ground-based system <br />housed in a trailer analyzes the data after each fl ight. Data archival <br />reproduction also is carried out. <br /> <br />CONTRACTOR: Western eather Consultants, Inc., Durango, Colorado <br />CONTRACT NO. 8-07-83- 0010 <br />PRINCIPAL INVESTIGATO: Curtis Hartzell <br />CONTRACT PERIOD: March 15, 1978, to February 28, 1982 <br />FY79 FUNDING: $875,3 7 <br />PURPOSE: Provide met orological observation and forecasting support to <br />HIPLEX <br /> <br />Western Weather Consultants, Inc., provides meteorological support services <br />for the Montana HIPLE program dul"ing the summer field season and summari zes, <br />evaluates, and analyz s compiled data during postseason periods.
