Climate Modification and National Security.
The RAND program on climate dynamics for environmental security begins with the concept that the United States might be harmed either inadvertently or maliciously by changes in the climate elsewhere on the globe. The program to develop a methodology to anticipate climatic changes has been in progress at RAND for about a year, and includes 9 subprojects: (1) determination of changes in the mean state of an atmospheric model with different boundary conditions and different initial conditions, (2) experiments with the Mintz-Arakawa model to determine the direction of change, (3) experiments with a newly developed barotropic ocean model, (4) a study of the effect of turbidity and cloudiness on atmospheric radiation, (5) development of a small-scale convective cloud model, (6) establishment of new numerical analysis methods, (7) comparison of the present model with alternative models, (8) continuation of the study of climate as it has been recorded or deduced in the past, and (9) preparation of the ILLIAC IV to program cloud models in the future. 9 pp. Ref.
