Method of generating convective weather avoidance strategy for terminal flight

A method for generating a weather avoidance strategy for flights, the method comprising:

• collecting, by a computing apparatus comprising a processor and a storage unit, historical radar trajectory data and historical weather data of various flights in a predetermined airport terminal area, and receiving, via a communication unit, weather forecast data in real time;
• determining an arrival and departure typical flight route of each flight in the predetermined airport terminal area on a basis of the historical radar trajectory data and the historical weather data;
• acquiring deviation information indicating deviation of each flight due to severe convective weather on the basis of the historical weather data, the arrival and departure typical flight route, and the historical radar trajectory data;
• determining flight deviation probabilities under different weather conditions on the basis of the historical weather data, the arrival and departure typical flight route and the deviation information, to generate a flight deviation probability chart;
• constructing a weather avoidance probability figure of the predetermined airport terminal area on the basis of the weather forecast data and the flight deviation probability chart, comprising:
• dividing the predetermined airport terminal area into a plurality of geographic grids defined by longitude and latitude;
• and
• determining, for each of the geographic grids, a flight deviation probability based on the weather forecast data and the flight deviation probability chart;
• formulating, by the computing apparatus, a weather avoidance strategy for each flight in the predetermined airport terminal area on the basis of the arrival and departure typical flight route and the weather avoidance probability figure, comprising:
• determining whether geographic grids having deviation probabilities within a predefined probability range satisfy a threshold condition relative to cross-sections of the arrival and departure typical flight route;
• and
• selecting a flight operation strategy including at least one of airborne holding, diversion, or route modification based on the determination;
• and
• controlling arrival and departure flight routes for each flight under convective weather conditions in the predetermined airport terminal area based on the weather avoidance strategy.
