Popis: The feasibility of using the fluorescent properties of zinc sulfide powder to study air motions in the vicinity of jet streams was studied by releasing 230 kg of the substance above the subtropical jet in central Australia and later in Western Australia. Zinc sulfide was detected in some of the air samples obtained at the ground in Australia and New Zealand as far as 7000 km from the source and at various altitudes over eastern Australia. It is concluded that this tracer could be useful for studying air motions on such a large scale but that transport mechanisms involving clouds may also be important. Very rapid downward transport was a feature of both experiments. A relationship appears to exist between ice nucleus concentrations and the fallout pattern of the zinc sulfide.
