Abstract:

The present work is part of an effort to develop a complete and accurate model for the three-dimensional motion of radioactive nuclear weapon debris released in the earths atmosphere at altitudes from 25 km to 130 km. The time development of passive cloud surfaces in a empirically derived seasonally dependent mean zonal and meridional wind field is followed using a very simple advection code. Zonal wind fields are based on Groves CIRA 1972 model and meridional fields are based on a 1969 paper by the same author. Both models are fits to extensive experimental data, time averaged over one-month time intervals. Test runs are presented, showing the effects of releasing the cloud during different months and at different points over the earth.
