<br />. <br /> <br />e <br /> <br />3 <br />(AM) of Heymsfield (1986) was used to study the growth using more <br />sophisticated assumptions about the aggregation process. Particle <br />size and habi t data fran the Uni versi ty of Wyoming King Air were <br />compared wi th model results. <br /> <br />. <br /> <br />. <br /> <br />1.1 OBJECl'IVES OF THE RESE~ <br /> <br />. <br /> <br />e <br /> <br />The objectives of this research are: <br /> <br /> <br />(i) To study the growth and habit of ice particles using <br /> <br />aircraft observations in seeded regions of a cloud. <br /> <br /> <br />(ii) To compare the aircraft observations with theoretical <br /> <br /> <br />predictions and, using the computer models as tools, identify <br /> <br />the origin of ice pa:rticles observed at the sampling level. <br /> <br /> <br />(iii) To study the effect of liquid water on the growth of ice <br /> <br />particles under conditions found in the SCPP. <br /> <br /> <br />(iv) Using a model of aggregational growth, identify the <br /> <br /> <br />conditions important for aggregation, and determine if theory <br /> <br /> <br />support the observed times of formation of aggregates in <br /> <br />seeded convective clouds. <br /> <br /> <br />(v) To study the ice crystal trajectories and the targeting <br /> <br />problem in general. <br /> <br />The 1 i terature review of the theory and numerical models of <br /> <br /> <br />growth by diffusion, accretion and aggregation is presented in <br /> <br />Chapter II. The data collection procedures during the field <br /> <br />operations are presented in Chapter III. Chapter IV contains a <br /> <br />detailed description of the PGM of diffusion and accretion, the AM <br /> <br />.e <br /> <br />. <br /> <br />.e <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br />
