Abstract
The discretization of long-range transport models leads to huge computational tasks. The advection (the transport due to the wind) and the chemistry are the most difficult parts of such a model. Normally splitting procedures are used and one tries to develop optimal methods for the advection part and for the chemistry part. Some results obtained in the attempts to design good sets of methods which work well for the coupled advection-chemistry sub-model will be presented. Runs on a Silicon Graphics POWER CHALLENGE computer indicate that the methods perform reasonably well and high speed-ups can be achieved with minimal extra efforts. However, more efforts are needed to get closer to the peak performance of this computer.
