EFFECTS OF NUCLEAR WAR
"Nuclear Winter: Science and Politics," B. Martin (Dept. Sci.,
Univ. Wollongong, Wollongong NSW 2500, Australia), Sci. & Public Policy,
15(5), 321-334, Oct. 1988.
Explains that the nuclear winter controversy is an interaction between
science and politics; political interests have influenced the degree of
scientific attention and research approach, while scientific results have been
used to intervene in political debates. Gives specific examples of disagreement
among researchers and provides an extensive reference list on the topic.
"Two-Dimensional Simulations of Possible Mesoscale Effects of
Nuclear War Fires, F. Giorgi (NCAR, POB 3000, Boulder CO 80307), J. Geophys.
Res., 94(D1), Jan. 20, 1989.
"1. Model Description," 1127-1144. Describes simulations of
possible mesoscale effects of smoke injections from nuclear war fires obtained
by coupling a two-dimensional mesoscale meteorological model to an aerosol
model. Describes development of models and gives an example of model performance
via a simulation of the development of circulations similar to sea breezes,
induced by contrasts in soil moisture available for evapotranspiration.
"2. Model Results," 1145-1164. Simulations are carried out for
different fire types (city center, suburban and forest fires), aerosol loadings,
particle properties and atmospheric conditions. Analyzes three effects which
develop on spatial scales of 10-500 km and time scales of 1-2 days and can be
important for assessments of environmental impacts of nuclear war: smoke-induced
formation of clouds and precipitation and efficiency of smoke removal; smoke
vertical transport; and surface cooling induced by the smoke absorption.
Discusses how results can be used in the design of injection scenarios for
general circulation model simulations.
"Enhancement of Surface Cooling Due to Forest Fire Smoke," A.
Robock (Dept. Meteor., Univ. Maryland, College Pk. MD 20742), Science,
242(4880), 911-913, Nov. 11, 1988.
Smoke emitted from forest fires in northern California in September 1987 was
trapped in a valley by an inversion for 3 weeks. The smoke strengthened the
inversion by preventing surface warming by solar radiation, which enhanced the
smoke trapping and the surface cooling in a positive feedback loop. These
results may have implications for nuclear winter.
