The National Meteorological Centre (NMC) undertakes the responsibility of issuing forecasts and warnings for 13 different types of hazardous weather conditions within the next 24 hours. These include typhoons, heavy rain, severe convective weather, blizzards, cold waves, gales at sea, sandstorms, low temperatures, high temperatures, frosts, ice storms, heavy fog, and haze. Additionally, NMC collaborates with the departments of natural and water resources to issue warnings for 4 categories of meteorological disasters, which are floods in small and medium-sized rivers, flash floods, geological disasters, and agricultural meteorological disaster risks.
In recent years, NMC has continuously optimized and improved its dynamic tracking of heavy rain, fine-grained analysis of extreme events, and core forecasting techniques.?As a result,the accuracy of heavy rain forecasts has increased annually?under various lead times. Based on the intelligent grid precipitation and meteorological disaster risk warning, the small and medium-sized river, flash flood, and geological disaster warning operational system has also been continuously improved. A distributed hydro-meteorological model and a disaster risk model based on the hydrological model at the basin level have been constructed, effectively enhancing the guidance capability for hydro-meteorological operations at all levels of weather stations.
CMADaas, the cloud-based meteorological big data platform, is a "processing plant" for China's massive meteorological data, which comprehensively manages and provides meteorological "data, computing power and algorithm" resources, and supports "cloud + terminal" meteorological operations.
The meteorological integrated real-time monitoring system -"Tianjing", realizes the intensive national meteorological integrated monitoring and operation and maintenance, which adopts vivid forms of expression to visually present the national meteorological information resource capacity and operation status, and system operation status, etc., and the whole process of data flow, so as to explicitly display the national meteorological informatization operation.
"Tianheng Tianyan" is a comprehensive meteorological observation product system integrates weather radars, wind profiles, cloud radars, microwave radiometers, large-scale unmanned aerial vehicles, and data related to lightning, water vapor, ground, sounding, ecology, atmospheric composition, oceans and other?multi-source data information, which is characterized with diversified observations, and massive and informative data.
