On April 28, 2010, Numerical Weather Prediction Center of China Meteorological Administration (CMA) was established. During a ten-year period, a suite of national numerical weather prediction systems, based on independent technology, has been developed and put into operation.
Development of GRAPES system
In 2000, under the support of the Scientific and Technological Support Project of Ministry of science and technology of China, CMA started to develop next generation NWP system-Global-Regional Assimilation and PrEdiction System(GRAPES). With the establishment of NWPC in 2010, the operation-oriented R&D was enhanced. Several core techniques were developed including physical processes optimization,4D-var data assimilation, multi-platform and multi-sensor satellite data assimilation, high performance computing etc. .
