This site has the comprehensive archive of meteorological satellite "Himawari" images since 1978, and offers a typhoon database of about 180,000 typhoon images since 1979 and typhoon best tracks since 1951 to search by date, name, location, cloud patterns, and so on. Recently this site started to provide typhoon forecast information, but the latest typhoon information, weather forecast, advisories and warnings should be obtained from reliable sources such as "Japan Meteorological Agency: Typhoon Information" and other sites. Updates may be delayed due to the status of network between data sources.
Images of past typhoons from 1979 to this year are archived.

In the informatics community, there is a growing interest in discovering relevant information from the huge amount of data that is overwhelming even in our everyday life. In the scientific communities such as earth science, bioinformatics, physics, the explosive amount of data stream that sensors generate continuously urges us to develop a set of techniques to discover relevant information that is hidden in the middle of the data in near real-time.
The project "Digital Typhoon" constructs the large collection of typhoon images as a typical example of spatio-temporal scientific database, and aims at developing techniques to "mine" or discover relevant knowledge which may be useful for typhoon analysis and prediction. This web site will reveal a part of our achievements.
