How does a prog differ from an analysis?

What will be the ideal response?


ANSWER: A final forecast chart representing the atmosphere at a specific future time is called a prognostic chart or prog. Computer progs are known as machine-made forecasts. Modern electronic computers can analyze large quantities of data extremely fast. Each day, the many thousands of observations transmitted to NCEP are fed into a high-speed computer, which plots and draws lines on surface and upper-air charts. Meteorologists interpret the weather patterns and then correct any errors that may be present during their analysis. The routine daily forecasting of weather by the computer has come to be known as numerical weather prediction. To help forecasters handle all the available charts and maps, high-speed data modeling systems using computers are employed. The communication system in use today is known as AWIPS (Advanced Weather Interactive Processing System).
