PROBLEM TO BE SOLVED: To provide weather prediction bulletin containing the wind distribution for airdrome control area. SOLUTION: At weather prediction operating unit CP a weather prediction model is produced using the predicted wide-area weather data supplied regularly from the weather data server DS as the initial value and the observed products of weather condition containing the wind distribution within the airdrome control area derived from the weather observing device WD is updated successively through the data assimilation to that model. On the other hand, the high resolution weather prediction containing wind distribution at any time and at any location within the area is operated from prediction model and the operational products is presented as the weather prediction bulletin. Moreover, the occurrence of wind shear/down-burst is predicted to detect from the weather prediction operation products and activities is urged for preventing the approach of flight vehicles into the predicted area.
