In recent years, flood damage in urban areas due to localized heavy rain has increased. In order to reduce the flood damage, improvement of rainfall forecast accuracy has been expected. To improve the rainfall forecast system (radar image extrapolation method), we have developed a technique to identify the stage of storm life cycle. This is the first study to identify the stage of storm cell using a hydrometeor classification which is estimated from X-band polarimetric radar observations.<br>We investigated the relation between the stage of storm life cycle and existing ratio of hydrometeor aloft in a storm cell. The membership functions between the stage and hydrometeor existing ratio was created based on the tracking results of storm cells. The result of applying fuzzy logic using the membership function to various storm cells shows a good agreement.
