for his first numerical weather prediction. Squares marked 'P' provided atmospheric pressure values; those marked 'M' gave atmospheric momentum.
             Perhaps the most prevalent usage of weather forecasting became apparent in World War 2, in which weather became an important aspect of the battlefield. Quite simply, radiosondes (weather balloons incorporating radio transmitters), rockets, and aircraft were used to map the different atmospheric levels. It became apparent that in order to perform the vast number crunching operations that digital computers would have to be utilised.
             John Von Neumann, a mathematician was a key figure in developing the application models that would be used on the Electronic Numerical Integrator and Computer (ENIAC). The ENIAC was 3 meters tall, the size of a small house and comprised of 18,000 vacuum tubes. The problem was essentially based on non-linear problems of fluid dynamics (describes the major motions of atmosphere and oceans). In 1949, the first weather prediction using a computer was prepared.
