After the war, Richardson published a detailed report, Weather Prediction by Numerical Process, so that others might learn from his mistakes. At the end of his account, he envisioned partitioning the earth’s surface into 3,200 meteorological cells, relaying current observations by telegraph to the arched galleries and sunken amphitheater of a great hall, where some 64,000 human computers would continuously evaluate the equations governing each cell’s relations with its immediate neighbors, maintaining a numerical model of the atmosphere in real time.
