YOKOHAMA, JAPAN-- The global climate picture produced by current climate models is too crude to make accurate predictions based on small fluctuations in inputs such as temperature. But next month, Japanese scientists will start to operate a $310 million supercomputer that can digest a much more detailed model and, researchers hope, spit out better answers. The supercomputer will also add a new dimension to studies of Earth's interior by allowing the first global-scale simulations of the interaction between core and mantle, and between mantle and crust.
