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.
