Abstract: Measurements have been made of the time lag which silver iodide particles exhibit in the nucleation of ice crystals at temperatures between ?8C and ?16C. The time tag is approximately exponential, the decay constants being ...

Abstract: A 10-day experiment is described in which simultaneous measurements of ice nucleus concentrations have been made in upslope and downslope wind regimes on the island of Hawaii, near sea level at Hilo airport, at Mauna Loa ...

Abstract: A long-lived cumulus cloud off the southern coast of Australia was found to contain ice crystals, even though the coldest temperature in it was about ?4C. Two instrumented aircraft made successive passes through the cloud ...

Abstract: 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 ...

Abstract: Finely divided zinc sulfide and freezing nuclei in the form of silver-iodide smoke were released from separate generators at the same time from the same position on the ground. Both were detected simultaneously at distances ...

Abstract: Isolated cumulus clouds with supercooled tops were seeded from an aircraft. Either a large (20 gm), small (0.2 gm) or zero quantity of silver iodide was used, with random choice of treatment. The amount of rain which fell ...

Abstract: Comparisons between ice nucleus concentrations as measured by membrane filters and cloud chambers show good agreement when natural ice nuclei are being sampled. Wide discrepancies in the case of other test aerosols, ...
