What is the World Meteorological Center? What is its status in the World Meteorological Organization?

At the 69th meeting of the Executive Committee of the World Meteorological Organization (WMO) held in May this year, China Meteorological Bureau was officially recognized as the World Meteorological Center (WMC). This indicates that the overall level of China's meteorological service has entered the world's advanced ranks, played a leading and core role in the world meteorological service institutions and technical exchanges, and further improved China's marking degree, international influence and international contribution rate on the world meteorological stage. According to the latest WMO? According to the Manual of Global Data Processing and Forecasting System, the current global meteorological operational forecasting system consists of three layers: World Meteorological Center, Regional Specialized Meteorological Center and National Meteorological Center.

The requirement of the World Meteorological Center is to have the ability to run the global deterministic numerical weather forecast system, the global ensemble numerical weather forecast system and the global long-term numerical forecast system simultaneously. This puts a very high demand on the technical level and product quality of the numerical forecasting business of the reporting organ. This meeting confirmed five new world meteorological centers. Apart from China, these four centers are located in european centre for medium-range weather forecasts, Exeter, Montreal and Tokyo. Previously, there were three world meteorological centers, located in Washington, USA, Moscow, Russia and Melbourne, Australia.

China Meteorological Bureau is the only world meteorological center in developing countries. In the past few years, China Meteorological Bureau has attached great importance to the development of numerical forecasting business, continuously improved the independent research and innovation ability of numerical forecasting core technology, and developed and improved the technical system of numerical forecasting business around the core goal of improving forecasting accuracy. At present, we are speeding up the construction of a numerical forecasting business system focusing on GRAPES, which will make technical reserves for the development of the next generation numerical forecasting model system. The meeting held that the National Meteorological Center of China Meteorological Bureau is a professional meteorological center in the field of atmospheric sandstorm forecasting, which helps China and other Asian countries to prevent the impact of sandstorms.
