Collaboration between Met. Services and Disaster Prevention Authorities JMA promotes the provision of effective meteorological information services through collaboration with river management authorities, local governments, etc.

Example of collaboration Flood Forecasting Services…River Bureau Sediment Disaster Alert …Sabo Department/Prefecture Weather Bulletin for Fire Prevention … Fire and Disaster Management Agency 　 (FDMA)

Sediment Disaster Alert JMA Prefecture Information Exchange (Forecaster） (Sabo; Erosion and sediment control ） Sediment Disaster Alert Alert on sediment disaster for each city. Expected rainfall intensity Graphical information in addition to plain text warning Joint Issuance Local Authorities (City and others)

Sediment Disaster Alert Experiments to ensure feasibility in eight prefectures in 2004. Operational services start in some prefectures in 2005.

Weather Bulletin for Fire Prevention Humidity Observational Data Weather Bulletin for Fire Prevention Fire Headquarters JMA Fire Alert in a prefecture (example) Trial in three prefectures in 2004. Classification A Classification B Classification C Not particular

Future Plan Improvement of Prediction through Data Exchange Joint Technological Development for Advanced Flood Prediction Meteorological Information Exchange for Disaster Prevention

Improvement of Prediction through Data Exchange improvement of forecast accuracy JMA（AMeDAS） With data from 1300 JMA raingauges (AMeDAS) With data from 5200 raingauges including non JMA observations Prefecture data Frequency diagram showing observed (horizontal) vs predicted (vertical) rainfall amount for the case of T0310. The right graph (with data provided from outside of JMA) shows more concentration around the diagonal, indicating enhanced accuracy. MLIT data

Joint Technological Development for Advanced Flood Prediction Estimation of run-off flowing into the river from precipitation analysis and prediction. Estimation of river flow from the river feature, upstream flow, topography, etc.

Meteorological Information Exchange for Disaster Prevention Information Sharing System based on Advanced IT Infrastructure Satellite network FDMA Prefecture Predigested maps and information City Prefectural LAN Disaster prevention information system JMA Zoom up the area of concern 　　 　 　 　 ○○市大雨警報発表中 Data Format for Cell-Phone Services Cell-phone Volunteer fire fighter

Conclusion Collaboration with other disaster prevention authorities Exchange of observational data Improved prediction accuracy Enhancement of Information sharing systems rapid and reliable dissemination of products Combination of meteorological and other expertise Product supporting disaster response more directly Mitigation of Disaster
