Abstract:

The initial phases of a quasi-real-time test of the use of computer programs employing modern weather techniques, reported here, examined their performance under operational conditions. Criteria were estimates of feasibility, meteorological accuracy, and timeliness. Analyses and forecasts were prepared from live data. The results were not transmitted to aviation users. Two meteorological techniques were tested a a statistical method for predicting ceiling and visibility up to seven hours, and b an analysis method based on elements reported from ground stations, e.g., ceiling, visibility, pressure, temperature, dew point, wind speed, and precipitation. The implementation of modern weather techniques is feasible. Many problems were met, none were insurmountable. Meteorological accuracy of the techniques could deteriorate significantly due to missing andor erroneous data. Standardization and improvement of codes and communications discipline would help. Forecasts and analyses were ready for communications by 30 minutes after observation time. Significant improvement in timeliness can be achieved by utilizing real-time data channels, minimizing the use of magnetic tape in data processing, and rewriting new operational computer programs in lieu of re-programming developmental programs.
