Abstract: The behavior of nuclear bomb debris in the atmosphere is reviewed in order to see how far such debris might be used as a tracer in atmospheric physics. Much debris seems to be captured by orographic precipitation, and ...

Abstract: Stratospheric air is stably stratified, but vertical mixing is indicated by measurements of ozone and nuclear bomb debris. Tracer measurements suggest a mean net circulation by which air enters the stratosphere in the ...

Abstract: The problem analyzed is the release of polluting material into a turbulent atmosphere from a multitude of known sources dispersed in time and space. Each source produces a cloud instantaneously. Mathematical procedures are ...

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 ...
