Richardson’s Fantastic Forecast Factory

https://www.emetsoc.org/resources/rff/

Richardson describes how “A myriad computers are at work upon the weather of the part of the map where each sits … . The work of each region is coordinated by an official of higher rank.” The image divides the globe into about twenty zones.

The upper floor, with the desks of four senior clerks, is shown below the central column. A banner on each desk identifies a major figure in the history of computing. The Director of Operations stands on a dais atop the central tower, “like the conductor of an orchestra in which the instruments are slide-rules and calculating machines”. He coordinates the computations, signalling with a red spotlight to those who are racing ahead, and with a blue light to those who are behindhand.
