THE DEVELOPMENT OF A WATER-SURFACE-BURST FALLOUT MODEL: THE RISE AND EXPANSION OF THE ATOMIC CLOUD
NAVAL RADIOLOGICAL DEFENSE LAB SAN FRANCISCO CA
Pagination or Media Count:
A water-surface-burst fallout model is being developed in three parts 1 cloud rise and expansion 2 particle formation and 3 particle fall through the atmosphere. Part 1 is discussed in detail. The cloud is described by a set of equations for rate of rise, temperature, water content and other parameters, using an entraining parcel method. The equations allow for variations in atmospheric temperature, pressure and humidity as well as in initial cloud height, temperature, and airwater energy partition. Temperature and volume are calculated by extensions of standard meteorological equations.
