The Japan Meteorological Agency (JMA) is one of the Regional Specialized Meteorological Centres for the general-purpose activities of the World Meteorological Organization (WMO). In June 2019, JMA started the provision of the global deterministic Numerical Weather Predictions (NWP) according to the manual on the Global Data-Processing and Forecasting System (GDPFS) edition 2017. The manual specifies the standard procedures of verifications, in which surface field verifications against SYNOP observation are listed as the mandatory services for the WMO members.
This presentation provides some results of the surface field verification of JMA’s deterministic NWP comparing with ones for other participating NWP centers. The verification results show the diurnal and seasonal variabilities of the models' error. The results of the verification will provide some important aspects for the future improvements of the global NWP models.
