Abstract
<p> The meteorological field data from 1979 to 2019 in northern Kyushu and Chugoku districts were classified by The SOM, which consists of 696 units (patterns) and 45 groups. In the map created in this study, the cyclical winds caused by typhoons and low-pressure depression are located in the upper part of the map. It was found that the typhoon that caused the storm surge disaster in northern Kyushu and Chugoku region was classified into the 696th unit of group 45. From the SOM pattern recognition of meteorological fields obtained by GSM or MSM, it would be possible for residents to provide information that a meteorological field characterized by an approaching typhoon is similar as the past one that actually caused serious storm surge disaster.</p>
