Research Of Related Technologies On Forecast System For Terminal Aerodrome Forecast

With the development of Meteorological Database Management System and Data Mining Technology, the study of weather forecast system is becoming the key and hot research field. Weather forecast system can provide the deciders with more professional support in making timely and accurately forecast.Weather forecast system is a complex and multi-disciplinary system. The main task of the master's thesis is to study the basic problem and implement method of Terminal Aerodrome Forecast System. This thesis is include the implement framework of Terminal Aerodrome Forecast prototype system, a Terminal Aerodrome Forecast report decode algorithm based on finite automata, a method of establishing forecast model based on model tree and building a prototype system for verifying the availability and feasibility of the algorithm and technology.The main works are as following:1. Based on the analysis of business knowledge in Terminal Aerodrome Forecast and the process of data mining, putting forward an implement framework of Terminal Aerodrome Forecast system, and making a prototype system.2. Proposing a Terminal Aerodrome Forecast report decode algorithm based on finite automata in formatting meteorological data. It can help to format and provide valid meteorological data for the system. With the grammar and lexical and the back-tracing automata, the algorithm can improve the validity of meteorological data.3. Researching the method of building a Terminal Aerodrome Forecast model using model tree. It includes the data collection, preprocessing the data, building the model and evaluting the result.
