Abstract:

A brief study was made of three fallout prediction models the ENW Effects of Nuclear Weapons model, the Miller model, and the WSEG-10 model. Each of these models used an effective wind that had constant direction and speed. A FORTRAN computer code of the Miller model was prepared by the author and is available in the report. To ascertain the effects of more realistic winds that varied direction and speed with altitude, the model utilized an altitude dependent wind as well as a thin stabilized cloud, and fall time equations. This model was prepared as a FORTRAN computer code and the code is included in the report. The two most significant results of the variable wind model are the asymmetric pattern produced on the ground and the non-linear centerline of that pattern. The model allows the user to introduce his own description of the physical processes of fallout deposition.
