Happy Birthday Lewis Fry Richardson

Thanks to the Writer’s Almanac:

It’s the birthday of physicist and psychologist Lewis Fry Richardson, born in Northumberland, England (1881), who was the first to apply mathematical techniques to predict the weather accurately. During WWI, Richardson served as a driver for the Friends’ Ambulance Unit in France. During the intervals between transporting wounded soldiers from the front, he manually computed the changes in pressure and wind at two points. From this information, he wrote his 1922 book, Weather Prediction by Numerical Process. The problem with his theories was that it took him about three months to predict the weather for the next 24 hours. His system did not become practical until the advent of electronic computers after World War II.
