OF GENERAL INTEREST
"Changes of Tropical Sea-Air Interaction Processes over a
30-Year Period," H. Flohn (Meteor. Inst., Univ. Bonn, Auf dem Hügel
20, D-5300, Bonn, FRG), A. Kapala, Nature, 338(6212), 244-246,
Mar. 16, 1989.
Reports investigations on sea-air interaction processes along the main
shipping routes of equatorial oceans over the period 1949-1979. Results indicate
an intensification of the hydrological cycle, especially over the warmest
oceans, and also suggest tropical circulation changes. As the sea-air fluxes of
CO2 and H2O are linked, these results suggest that the man-made increase in the
atmospheric CO2 concentration could be the primary trigger of a chain of
processes within the tropical branch of the climate system, and intensification
of the cycle could be considered a signal of global warming.
"Implications of a Global Climatic Warming for Agriculture: A
Review and Appraisal," B. Smit (Dept. Geog., Univ. Guelph, Guelph, Ont. N1G
2W1, Can.), L. Ludlow, M. Brklacich, J. Environ. Qual., 17(4),
519-527, Oct.-Dec. 1988.
Classifies and reviews those studies examining implications of climatic
warming, recognizing three approaches: crop yield analysis, spatial analysis and
agricultural systems analysis. Much remains to be learned, but current evidence
suggests that a warmer climate could create a more favorable environment for
wheat and grain corn in Canada, northern Europe and the U.S.S.R. and restrict
opportunities in the United States. Extensive reference list included.
"Chlorofluorocarbons, Stratospheric Ozone, and the Antarctic
`Ozone Hole,'" F.S. Rowland (Dept. Chem., Univ. Calif., Irvine CA 92717),
Environ. Conserv., 15(2), 101-115, Summer 1988.
A detailed review that discusses 1) scientific background and status of
current investigations, 2) the major technological uses of CFCs and available or
foreseeable alternatives to them, and 3) the policy status and regulatory
activity involving present or proposed future restrictions of CFC emissions.
Extensive reference list.
"Climatic Response to Large Atmospheric Smoke Injections:
Sensitivity Studies with a Tropospheric General Circulation Model," S.J.
Ghan (Lawrence Livermore Nat. Lab., Univ. Calif., POB 808, Livermore CA 94550),
M.C. MacCracken, J.W. Walton, J. Geophys. Res., 93(D7),
8315-8337, July 20, 1988.
Couples a tropospheric general circulation model with a Lagrangian trace
species transport and removal model to determine the climatic response to
continental-scale smoke injections, such as would result from a nuclear war.
Considers a variety of sensitivity experiments such as sensitivity to the mass,
location, day, season, duration, altitude, composition and size distribution of
the smoke injection. Found, for example, that the assumed initial aerosol size
distribution of injection plays an important role in determining climatic
response. Also discusses the importance of various feedback processes.
