Grosner, B

The purpose of this thesis was to develop a model that would predict world-wide fallout in the Northern Hemisphere by modeling the stratospheric-to-tropospheric exchange processes. Inherent in the development of the model was to keep it simple enough to be programed into a personal or home computer. The model is adaptable to the dispersion of debris clouds that are made up of particles in the stratosphere, other than just those from nuclear detonations. The model consists of injecting a radioactive cloud into the stratosphere and allowing it to grow with time. As the cloud reaches the tropopause it is injected to the troposphere using an air mass flux which is a function of latitude and season. The model is dependent on the assumed particle size distribution of the cloud. The model, using the assumed particle size distributions that have been postulated, is compared to an empirical model based on the 1958 nuclear tests of the U.S. and USSR.
