NEW CLIMATE MODELS
The Bush Administration is supporting
development of a new generation of supercomputers for predicting climatic
change. The process of deciding how to go about the job, being coordinated by
the Office of Science and Technology Policy, is discussed in "Climatologists
Debate How to Model the World" by R.A. Kerr (Science, pp.
1082-1083, Nov. 23, 1990). One approach is the Computer Hardware, Advanced
Mathematics and Model Physics (CHAMMP) Climate Modeling Program proposed by the
Department of Energy. (See Reports, this Global Climate Change Digest issue--Jan.
1991.) CHAMMP has been criticized for focusing too much on engineering to
increase computer speed, to the exclusion of scientific development. The other
approach being considered is the Climate System Modeling Program (CSMP) proposed
by the University Corporation for Atmospheric Research. The latest version of
that plan concentrates on improving scientific weaknesses in existing models
such as cloud processes and their effects, how the oceans absorb carbon dioxide,
and testing model performance using the geologic record. Probably several
competing models will be supported, using elements of both proposals. The
article also examines the outlook for development of European models at the new
Hadley Center for Climate Prediction and Research in Bracknell, England, the Max
Planck Institute in Hamburg, and elsewhere.
A request for CHAMMP grant applications, due Feb. 12, 1991, was published in
the Dec. 5 Federal Register.
