Data processing requirements for the purposes of numerical weather prediction

The physical background and historical development of numerical weather prediction is summarized. The nature of the mathematical problem and the work-load for a digital computer are then described. The existing system of processing meteorological information (particularly upper air data) for operational weather prediction is examined in the light of the anticipated needs for operational numerical weather prediction. The critique exposes deficiencies which may be intolerable for operational numerical weather prediction. Some suggestions are offered for revamping the existing system utilizing modern technological advances.
