<br />. <br /> <br />airflow at diff4~rent levels toward the mountains. <br /> <br />The airflow is a <br /> <br />'factor controlling cloud formation and precipitation development. <br /> <br />., <br /> <br />Experiment :2: Kinematics of the particle growth environment <br /> <br />Single and dual-Doppler radar data were collected in order to esti- <br /> <br />mate the rate of lift of air just upwind of the Tushar Mtns and the <br /> <br />. <br /> <br />velocities of p.:lrticles' as they blow across the mountains. <br /> <br />From the <br /> <br />rate of lift of air estimates are made of the rate of release of water <br /> <br />substance within. the clouds. <br /> <br />Estimates can be made in future work of <br /> <br />. <br /> <br />the time available for particle growth. <br /> <br />Experiment 3: Spatial and temporal ciistribution of supercooled <br />liquid water <br /> <br />. <br /> <br />A steerable microwave radiometer located in the mountains'collected <br /> <br />information on the spatial and temporal distribution of supercooled <br /> <br />liquid water. <br /> <br />The relation of the liquid water to the changing <br /> <br />. <br /> <br />mesoscale kinematics is described in, this report. . The temperature of <br /> <br />the liquid water is inferred from lidar observations of the clouds. <br /> <br />Experiment .4: Refinement of radiometer and Ka-band radar data <br /> <br />. <br /> <br />An attempt has been made to add rangl~ information to the radiometer <br /> <br />liquid water data set using Ka-band radar information in order to gain <br /> <br />detail as to the physical location of liquid water. An attempt has also <br /> <br />. <br /> <br />been made to interpret the Ka-band radar circular depolarization ratio <br /> <br />~n terms of particle characteristics. This work is described in Snider <br /> <br />!:.!~. (1986). <br /> <br />. <br /> <br />Experiment 5: Hydrometeor trajectories <br /> <br />Trajectories taken by hydrometeors as they grow from cloud to pre- <br /> <br />cipitation sizes were to be described by tracking features in the radar <br /> <br />. <br /> <br />. <br /> <br />-25- <br />
