The Research of Aviation Dangerous Weather Forecast for Fog and Haze Based on BP Neural Network

摘要

The fog-haze, as one of the dangerous aviation weather, influences the pilot to see the runway in the air. It is very dangerous to flight for safe landing. Because of the existence of fog-haze, the phenomenon of plane's taking off or delaying is not uncommon. In this paper, analyze the main physical factors of fog-haze and establish model based on BP neural network; in addition, the forecasting performance of the model was tested; at last, the short-term forecasting operational system of fog-haze which can be used for aviation meteorological services is built based on software development techniques.
