Research And Implementation Of Data Mining Application In Meteorology

The meteorological data are the basis for developing the weather warning, weather forecasting, climate prediction, various meteorological services and scientific research. it is the driving force for the development of meteorological science. According to the text storage mode of history meteorological data for the file A0 in Hulun Buir 16 national meteorological station, proposes to use modern database storage technology to restore the historical materials, using the database storage method tries to solve some contradictions that text storage mode not easy to read and the statistical error easy to accure and so on. thus to realize the fast query of historical data in Hulun Buir meteorological elements in the vertical inspection, investigate the meteorological factors and the lateral correlation of Hulun Buir stations, do the following work:1, using the weather data in A0 file as the basis, analyzing its internal structure, study the abnormal situation of meteorological elements of meteorological data in the A0 file. analysis the reason of abnormal, completed the classification of abnormal meteorological data in the A0 file, according to the result of classification to propose a processing method, and making the procesing.2, in accordance with the three design principles of database, database design of all elements of the storage of 16 meteorological stations in Hulun Buir in the A0 file, according to the design build the data table of each element of each station in the database, and makes clear the meaning of various data of each field in the table, and finally through the VC++ programming language to comply meteorological data storage in A0 file in the Hulun Buir 16 station.3,to test the correctness after storing the meteorological data in the A0 file Oracle database in the 16 weather stations in Hulun Buir. the test results meet the various elements that original meteorological data in the A0 file, by the correctness of the test, the dump data can be assured use.4 the meteorological data in the A0 file are stored orderly after accomplishing the storage, it greatly facilitate the statistical and analytical work of historical data of meteorological elements in Hulun Buir, comply the horizontal relationship between meteorological elements.5, the introduction of regular expressions simplifies the query statement and enhanced the operations of querying data.The accomplishment of the meteorological data storage for the file A0 database storage is the first step of the order storage. meteorological data storage is a complex, precise and repeated process. we get more and more natural data with the development of the meteorological activities. it is important to the meteorological service how to play the role of historical data, meteorological service is fast and efficient generation of the required data, provided reliable support for economic and social development and disaster prevention and mitigation, serves for the peoples’ s happiness and health, it is worth to do further research.
