Abstract: Because of its relative insensitivity to changes of station location and to such natural phenomena as volcanic activity, precipitation is a promising weather element for the study of secular changes of the general circulation. ...

Abstract: The fate of airborne contaminants that enter a cloud with an overriding rain, independently generated, is considered by means of three differential equations which express the overall mass conservation of contaminant. The ...

Abstract: The rain cleansing patterns observed in five rain situations, all characterized by convective structures, are presented. The data comprise radioactivity and pollen concentrations measured in sequential samples of rain water ...

Abstract: The photoelectric raindrop-size spectrometer, developed to meet the need in modern meteorology for detailed information about rain, is described. Operating with minimum physical disturbance of the rain field, the present ...

Abstract: A radiochemical procedure developed to measure precisely nanogram amounts of the indium tracer used in the study of circulations and rain scavenging processes in severe convective storms is described. The tracer indium ...

Abstract: A configuration with rain falling through a shallow flow of pollution-loaded air is examined theoretically. The pollution particles are made up of (NH4)2SO4 mixed with graphite. A numerical feedback technique is used for ...

Abstract: In a test of the use of indium as a particulate atmospheric tracer, both tagged and untagged rain showers were sampled at ground level in Oklahoma during May 1967. In 29 samples of untagged rain 6±3 nanograms of In per ...

Abstract: In an effort to determine whether it is feasible to use tracer techniques in the study of circulations and rain scavenging processes in severe convective storms, a pilot experiment using indium as tracer was conducted. A ...
