Meteorological databases: data mining applications and the effect of configuration of input in their performance

Abstract

Database management systems (DBMS) were developed to collect, store, organize and manage data. Data and information are retrieved from databases through known and clearly formulated questions (queries) and, additionally, through information discovery with the application of data mining techniques. Data mining algorithms operate on data and discover previously unknown information. In this thesis, a meteorological database is first designed and then target data is used in data mining applications and for conducting research work using a modified Knowledge Discovery from Databases (KDD) procedure. Data Mining applications concerning the operational data of the National Hail Suppression Program of the Hellenic Agricultural Insurance Organization are the Hail class estimation, Maximum hail size prediction, Prediction of hail suppression program seeding parameters, and Extraction of the observed convective day category index. The process of Knowledge Discovery from the meteorological databas ...
