Abstract: Based on the Meteorological Information Comprehensive Analysis and Processing System Version 4 (MICAPS4),the R & D team of Hebei Meteorological Observatory independently designed and developed a set of disastrous weather case retrieval and training system. By the collation and preservation of historical disastrous weather cases and associated data,this system has not only realized the retrieval,analysis,training,collection,management of the weather cases and other functions,but also solved the accumulation and use of historical data. In additon,it has expanded historical data application function of the MICAPS system. This system can be used in such aspects as disastrous weather forecast and warning business,scientific research and forecaster training. It is highly portable and has a good prospect of popularization and application.
