The second annual report describes the activities performed under seven separate tasks. These are the same tasks as outlined in the original proposal for the three-year program of research. These tasks dealt with the development of a trace chemical method of assessing the effects of seeding in a snow producing environment and the use of the stable isotopes of water for assessing the regions of ice-phase water capture in the cloud systems from which precipitation fell in the study regions. They also dealt with the theoretical aspects of these trace chemical programs of study and with the roles which trace impurities can play in affecting the growth characteristics of ice particles in supercooled clouds and of the shapes and number fluxes of ice crystals which occur under both natural and artificially seeded conditions. These tasks also included studies of the supercooled liquid water and ice contents of winter storms over the central Sierra Nevada, both spatially and temporally through the use of ground-based remote sensing radar and microwave radiometers. Some work was also conducted on the further development of new aircraft instrumentation for measuring atmospheric motions and the microphysical composition of winter orographic clouds.
