Hydrometeors consisting of a deposit of particles

(Section 3.2.1.4)

Deposits of fog droplets are observed especially in high areas where orographic clouds are frequent. The extent or depth of the deposits depends on the duration of the fog, the size distribution and number density of the fog (or cloud) droplets, and the speed of impact of the droplets. It is also a function of properties of the object, often a leaf, on which the deposit forms. When a large deposit occurs, the deposited droplets run together and drip on to the ground. In some circumstances, the amount of water falling from trees in this way during a single night may be as much as the rainfall from a moderate shower.
