Abstract:

The behavior of the nuclear cloud that would emerge after the simultaneous detonation of a large number of closely spaced megaton-class detonations has been examined. The initial adiabatic expansion to approximate pressure equilibrium and the subsequent rise of the cloud as the edge effects permit buoyant forces to lift the heated air were looked at with the aid of analytic calculations and analysis of two-dimensional hydrodynamic computer calculations. The use of existing programs for estimating fallout from such a nuclear cloud was also addressed. The most important conclusion is that superposition does not come close to predicting the nuclear cloud stabilization altitude or configuration, nor is that technique useful for predicting postattack winds or dust distribution. Recommendations for further study are made.
