Current Operational NWP Models
• Regional model (RSM)• Horizontal Resolution: 20 km• Updates: 2 times a day
• Global model (GSM)• Horizontal Resolution: 60 km• Updates: 4 times a day
• Mesoscale model(MSM)• Horizontal Resolution: 5 km• Updates: 8 times a day

Recent developments
Oct. 2006 BUFR winds of GOES-11/12 and MTSAT-1R started to be used instead of SATOB winds.
Feb. 2007 Assimilation of AP-RARS (Asia-Pacific Regional ATOVS Retransmission Service) data started.
Mar. 2007 Assimilation of GPS-RO (Radio Occultation) data from CHAMP started.
Apr. 2007 Assimilation of NOAA18/AMSU-A, MHS started.
Jun. 2007 Direct assimilation of clear-sky radiances of water vapour channel from MTSAT-1R/IMAGER started.
Aug. 2007 Assimilation of EARS (EUMETSAT Advanced Retransmission Service) ATOVS data started.
BUFR winds of GOES-11/12 and MTSAT-1R
•Data assimilation of BUFR coded AMV data with QI (2006.10)Improved thinningImproved use of QIImproved QCDiscontinue of Obs. Error adjustmentUse of MTSAT-1R hourly AMVs
• Extended forecast time from 15 hours to 33hours (03, 09, 15, 21 UTC Initial)
• Improvement of surface and boundary layer scheme, radiation scheme, cumulus parameterization scheme
• Use of Non-hydrostatic model in 4D-Var outer loop forecast model(2007.5)
Improvement of heavy rain forecasts.3-hour precipitation forecasts at 15hour forecasts from 21UTC 29 June, 2006 Initial. Old (left), New (center), Radar-AMeDAS observation (right)
Comparison of New 20km-GSM and RSM (Regional model)Forecast score against initial
Dec. 2005 and Jan.2006Aug. and Sep. 2004
Performance of the new 20km-GSM is superior to JMA Regional model (RSM 20km resolution).
Parallel run of 20km-GSM started 26 Sep. 2007 and 20km-GSM will be implemented into operational system in Nov. 2007.
Plans for JFY2007 and after
Nov. 2007• Implementation 20km Global model• Typhoon Ensemble • 0.25 deg. SST analysis data for GA• Use of Metop ATOVS data for GA
Mar. 2008• MTSAT-1R hourly AMV for MA• GOES11/12 and Meteosat7,9 CSR data for GA• ASCAT: need level2 ocean surface wind data• AIRS radiance data for GA• SSMIS radiance data for GA• GRACE GPS-RO data for GA• Improved assimilation of scatterometer Ocean Vector Winds (ambiguity winds)• Non-hydrostatic based 4D-Var for MA
After• New satellite data (IASI) and cloud/rain-affected radiances data• Radiance assimilation in MA
