As air travel has become a commonplace, the operational meteorological information based on user's demand with high productivity is being recognized as the valuable information. In addition, the information become essential in common life and is required by the various fields of industry as well. The geographical configuration of an airport and weather conditions become essential for aircraft landing and take-off. Thus, this study analyzes the meteorological elements associated with aircraft operation at the domestic airports such as Gimpo, Jeju, Ulsan Airports, and the threshold meteorological values of aircraft operation according to the direction of runways. There are two runways at Gimpo Airport such as 14R-32L and 14L-32R. The wind direction at Gimpo is characterized by the pronounced northwesterly that coincides with the runway direction. The days of low visibility are higher from October to December. In addition, fog is usually formed from 03:00 to 10:00 and disappears at about 10:00. Runway at Jeju Airport consists of two directions such as 24-06 and 31 -13. The wind direction is dominated by easterly or northwesterly. Easterly wind coincides with the runway direction, but northwesterly wind is a cross direction to that of runway. The visible distance is the lowest from May to June. In addition, fog at Jeju airport is mainly caused by sea fog. The foggy days and duration at Jeju airport are relatively lower than those in land due to high wind speed. There is one runway at Ulsan Airport, 18-36. The prevailing winds are northerly that coincides with the runway direction or southwesterly that acts as a cross wind with the runway direction. The least visibility is dominant in the period of May to June. In addition, due to geographical characteristics of the area, a dense radiation fog is frequently observed, but sea fog has little influence on it. The threshold meteorological values according to the runway direction for aircraft operation at Gimpo, Jeju, and Ulsan Airports have been set. In case the weather conditions are expected worse than the threshold, landing and take-off at a runway is restricted. Therefore, it appears that the accurate operational meteorological information has the capability of safe and economical operations of an aircraft, as well as convenience for users.
