  12. Rain Data Assimilation by 4DVAR 3hrs Rain Amount of 15hr Forecast from 4DVAR Analysis at 00utc 2/12/01 with assimilation of Radar-AMeDAS data Radar-AMeDASAnalysis The Rain Forecast from OI Anaysis

  13. Expectations from GPM for NWP Purpose • Analysis and Forecast • GPM is expected to contribute on accurate global rain, moisture, cloud and surface analysis with its huge amount of observations and • On frequent watch of severe weather systems including tropical cyclones and their accurate analyses. • Good global analysis will lead good long-term forecast. • Good global analysis and forecast will lead good regional analysis and forecast. • NWP model development • GPM is expected to contribute on not only producing climatic information but also the developments of NWP cloud, rain and snow fall schemes.

  14. Numerical Prediction Division of JMA and Joint Researches for Satellites • JMA/NPD • Management section (4) • Modeling branch (35) • Global modeling group (7) • Regional modeling group (7) • (New) Non-hydrostatic meso-scale modeling group (6) • Analysis group (7) .. (analysis scheme and QC) • (New) Satellite group (7) .. (satellite data assimilation) • Application branch (7) • Systems branch (11) • Joint Research for Sat. • JMA/MSC (8) • NASDA/EORC (2) We are preparing to use increasing satellite data!!
