When was the use of computers for weather prediction first considered?

As we have opined a number of times before in this column, the development of numerical weather prediction (NWP) — the use of computers to mathematically produce weather forecasts — is one of the most unheralded scientific advances of the 20th century.

Coupled with the ubiquitous mobile phones we all use, this revolution has enabled us, at a glance, to get a sense of the coming weather days in advance. Continue reading
