Outline of Final Research Achievements |
Recently, the short-time heavy rainfall events over urban areas have caused severe damage in Japan. In this study, a prediction method of short-time heavy rainfalls considering the effects of aerosols was developed. The method is based on an advanced cloud resolving model, which has been developed by principal investigator and collaborators, considering detailed urban environments including artificial land cover, anthropogenic heat, and building height distribution. The developed method was applied to a short-time heavy rainfall event which occurred in Osaka on 12 August in 2012. In an experiment considering aerosol effects, the amount of precipitation increased over southern part of Osaka plain, compared with the other experiment without aerosol effects. As a result, it was indicated that the precipitation amount can increase by the effects of aerosols in humid region like Japan in some rainfall events.
