Abstract:

The objective of this research is to create a two-dimensional cloud rise model that could be used instead of the current 1-D cloud rise model in the Defense Land Fallout Intepretive Code DELFIC option of the Hazard Prediction and Assessment Capability HPAC. The model includes numerical analysis of partial differential equations involving pressure, potential temperature, horizontal and vertical winds, and specific humidity. The 2-D model developed provides a much more detailed definition of the physical properties within the mushroom cloud than the 1-D DELFIC option. This is particularly useful in fallout studies on particle formation, fractionation, and particle location within the risingrisen cloud. The analysis model created for this study is the result of modifications to a convective cloud simulation. The primary modification to the convective cloud model is the incorporation of initial conditions for a nuclear cloud similar to those used in DELFICs initial conditions module.
