<br />5 <br /> <br />~ <br /> <br />C. CSU Research Tasks Identified <br />Two tasks were identified for CSU's research effort. <br />Task 1: Estimate of Maximum Modification Effect <br />At the 24 April 1985 meeting of the Utah/NOAA analysis <br />participants, a desire to calculate precipitation efficiency was <br />expressed. Due to the limitations imposed by a single rawinsonde upwind <br />of the Tushars and a limited precipitation gauge network, calculation of <br />precipitation efficiency in the thermodynamic sense of a water budget <br />across tbe barrier could not be done. At that meeting, CSU proposed an <br />alternative method which would relate more specifically to estimating <br />the maximum effect attainable by appropriate seeding. The approacb <br />proposed was to calculate the flux of supercooled liquid across the <br />mountain, using radiometer data and rawinsonde winds, and integrate this <br />flux over each storm to deter'mine the mass of liquid water crossing the <br /> <br />mountain u:nutilized in the precipitation process. CSU agreed to perform <br /> <br /> <br />these calculations in a correspondence with Dr. Long (8 May 1985). The <br /> <br /> <br />results of this task are summarized in Chapter II. <br /> <br />;; <br /> <br />'~ <br /> <br />Task 2: Case StudY Analysis <br />CSU's research interest and commitment included a case study <br />analysis of a STORM from the 1985 data set,. The obj~ctive was to <br />assemble a case study description of one storm event by integrating and <br />intercomparing measurements from a variety of observations. Some <br />unanticipated additional effort was required in reducing the Ka-band <br />radar dat~ -- Rochelle Blumenstein worked about three weeks on NCAR's <br />RDSS in Boulder. The case study of STORM 9 is given in Chapter III. <br />
