Geosciences and in particular numerical weather prediction are demanding the highest levels of available computer power. The European Centre for Medium-Range Weather Forecasts, with its experience in using supercomputers in this field, organizes every other year a workshop bringing together manufacturers, computer scientists, researchers and operational users to share their experiences and to learn about the latest developments. This book provides an excellent overview of the latest achievements in and plans for the use of new parallel techniques in meteorology, climatology and oceanography.

The proceedings have been selected for coverage in:

• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)

• Vector Returns: A New Supercomputer for the Met Office (P Burton)
• 10-KM Mesh Global Atmospheric Simulations (W Ohfuchi et al.)
• Implementation of the IFS on a Highly Parallel Scalar System (M Hamrud et al.)
• From MegaFlops to TeraFlops — The 10th ECMWF Workshop (G-R Hoffmann)
• Performance Analysis of the Scalable Modeling System (D Schaffer et al.)
• Performance and Parallelization of a Coupled GCM on the IBM SP4 (S Cocke et al.)
• Parallel Variational Assimilation in Aeronomy (T Kauranne et al.)
• A Computational Environment for Air Quality Model in Texas (B M Chapman et al.)
• and other papers
