Verification at EPS Lead Center

  • WMO designated RSMC Tokyo as the EPS Lead Center in 2005.

  • JMA has set up the EPS Lead Center Verification Web-site (http://epsv.kishou.go.jp/EPSv/) .

  • Currently verification tables of 5 NWP centers (ECMWF, CPTEC, CMA, KMA and JMA) have been put on the web.

  • JMA has been calling for other NWP centers to prepare their verification tables.

TIGGE Basic Verification by JMA

  • JMA proposed a plan for TIGGE Basic Verification using TIGGE database to support the Global EPS Operational Centers without verification system in the 4th meeting of the GIFS-TIGGE working group.

  • JMA has set up the TIGGE Basic Verification Web-site (http://epsv.kishou.go.jp/TIGGE/).

  • The verification tables of 10 NWP centers for 4 months (Aug. – Nov. 2008) was prepared with a trial. There are some missing tables because error data was included in downloaded data. The reason of error data could not be specified. JRA-25 was used as climate data.

  • TIGGE basic verification has been suspended because it needed much effort to continue.

  • Matsueda-san of AESTO working in MRI/JMA has set up the Monitor and Verification Web-site of TIGGE data (http://tparc.mri-jma.go.jp/TIGGE/index.html )as a volunteer work.

  • The monitor shows several kinds of verifications using data from Oct. 2007 to now. It is updated every month.
