Abstract: Warm rains at 62 stations in the northern hemisphere for a period of one year were examined geographically, seasonally and from other points of view by radiosonde data. The examination disclosed that warm rain fell more ...

Abstract: Many observations have been made of size distributions of raindrops, aggregated snowflakes, graupel and hailstones under various meteorological conditions. The size distributions have been studied in conjunction with upper ...

Abstract: No satisfactory standard field method has been established for the measurement of ice nucleus concentrations, although the filter technique is a promising candidate if the tendency for ice nucleus concentrations to decrease ...

Abstract: This article presents the results of an experimental investigation into the relationship between visual range and the size distribution of ice fog particles at Fairbanks, Alaska. An empirical function is developed for the ...

Abstract: Electric properties of ice fog crystals were studied using uniform and nonuniform electric-fields. It was observed that natural and artificial ice fog crystals had no significant net charge. An upper bound for the net ...

Abstract: Atmospheric ice nucleus concentrations were measured by the filter method daily for ten months at three ground sites in Alaska to determine the influence of long-range nucleus sources on the concentrations. The results ...

Abstract: Clear sky ice crystals or diamond dust displays are observed in polar regions, both remote and populated; when the temperature falls to ?20°C and where abundant sources of water vapor are present. In remote areas of the ...

Abstract: The production of the low temperatures which are responsible for ice fog in inhabited areas of interior Alaska would appear to be a classic example of clear sky radiative cooling under nearly polar night conditions. However, ...
