Abstract
A national program has been proposed that would develop a new generation of supermodels for the world's climate. The program is mandated to provide more climate models for some specific areas of the globe. A major problem facing the climate modelers is that they do not understand how the weather works well enough to tell a model how to simulate climate realistically. Computer speeds will have to increase by a factor of 10,000 over those of current machines in order to meet this task. Currently there are two schools of thought as to how to solve the problem: the Computer Hardware, Advanced Mathematics and Model Physics (CHAMMP) Climate Modeling Program has proposed to improve computer capacity, and the other approach proposed by the Climate Systems Modeling Program (CSMP) embraces independent ideas for plugging some of the scientific gaps, such as how clouds behave, how the ocean takes up carbon dioxide, and how the geologic record can be used to test a model's performance. A seven-agency program for all of global changes has requested a 1991 fiscal year budget of $1 billion dollars to try to solve the climate modelling problem - hopefully by attracting new talent.
