The China Meteorological Administration (CMA) hosts following Centres defined by the World Meteorological Organization (WMO)’s Manual on the Global Data-Processing and Forecasting System (GDPFS) (WMO-No. 485). This portal summarizes activities to meet general requirements and standards for World Meteorological Centre (WMC) and Regional Specialized Meteorological Centres (RSMCs) (more information on WMO website ).
As a World Meteorological Centre (WMC), WMC-Beijing provides WMO Members with a range of forecast products based on our global models. These include deterministic and ensemble medium-range forecasts and seasonal forecasts. Graphic products are available via the WMC Beijing website. A subset of products is available via the Beijing GISC (Global Information System Centre) for the WMO Information system (WIS).
Key Functions of WMC
l Data collection and quality control
Collection and quality control of the incoming observation that are used in the real-time operations of GDPFS.
l Provision of global forecast products
Provision of operational global deterministic numerical weather prediction (NWP)；Provision of global ensemble NWP；Provision of global numerical long-range prediction products；WMC-Beijing makes available some of the global forecast products via the WIS.
l Documentation on system and products
Documentation on the technical characteristics of the operational systems and on the products.
- Global deterministic NWP
- Global ensemble NWP
- Global numerical long-range predition
Model specification (pdf)
- Numerical ocean wave predition
Other Functions of WMC
l Verification of products
It is important to provide verification information on the Numerical Weather Prediction (NWP) products for the benefit of operational forecasters and to help the centres improve their forecasts. The standard verification measures are defined in Manual on the GDPFS (WMO-No. 485). WMC-Beijing produces verification statistics and makes them available to the Lead Centres for verification as follows:
- WMO Lead Centre for Deterministic NWP Verification
- WMO Lead Centre for EPS Verification
- WMO Lead Centre for Long-Range Forecast Verification
Conducting workshops and seminars on the preparation and use of WMC products.
l Long-term storage of data and products
Maintaining a continuously updated catalogue of data and products stored in the system.
l Reporting on compliance
Provision of information about the current implementation of the system.
l Regional centre for Atmospheric Sand and Dust storm Forecasts (ASDF)
al Regional centre for marine meteorological services
l Regional centre for nuclear environmental emergency response
