Abstract:

The theoretical bases of a land-surface-burst nuclear-cloud-rise model and details of development from the theoretical model of the DELFIC Cloud Rise Module computer program are presented. By use of this dynamic cloud rise model, histories of the rise, growth, temperature, and composition of the cloud are computed throughout virtually the entire period of its rise. Effects on the cloud development of atmospheric structure can be accounted for, and the development of a time-temperature history for the cloud allows fractionation of the radioactive weapon debris to be approximately accounted for in the Particle Activity Module calculations. Also described is the DELFIC Cloud Rise-Transport Interface Module CRTIM. The CRTIM corrects particle positions for wind-drift during the cloud rise time period and prepares the particles aloft inputs for the DELFIC Transport Module.
