Backscattering.-- The radiation scattered at 1800 to the direction of the incident wave. Coalescence. --The merging of two water drops into a single larger drop. Condensation nuclei. --A particle, either liquid or solid, upon which condensation of water vapor begins in the atmosphere. Convective cloud. - -A cloud that owes its vertical development, and possibly its origin, to atmospheric motions that are predomi- nantly vertical. Cumulus.-- A principal type of cloud in the form of individual, detached elements that are generally dense and possess sharp nonfibrous outlines. These elements develop vertically, appearing as rising mounds, domes, or towers, the upper parts of which resemble a cauliflower.

Glaciation. --The transformation of cloud particles from water drops to ice crystals. Hygrometer. --An instrument that measures the water vapor content of the atmosphere. Hygroscopic nuclei. --Those condensation nuclei composed of salts that yield aqueous solutions of a very low equilibrium vapor pressure compared with that of pure water at the same temperature. Ice-crystal nuclei. --Any particles that serve as the centers in the formation of ice crystals in the atmosphere. -Al- SECRET Approved for Release: 2018/01/30 006541157 -r Approved for Release 2018/01/30 006541157 _sg-ettrar� Nucleation. --Any process by which the phase change of a sub- stance to a more condensed state is initiated within the less condensed state.
