The 10～30 days extended-range forecasting technology is a worldwide problem, but it plays a very important role in meteorological disaster prevention and mitigation decision-making services and meteorological support services for major activities in China. In the past decade, China has carried out beneficial explorations in 10-30 days extended-range forecasting theory and technology and made some progress. Based on the introduction of the theory and technology of extended-range forecast, this paper systematically introduced the technical progress of China’s extended-range forecasting service; combining with the development trend of numerical model and the demand of future extended-range forecast, here we analyzed the specific technical problems and challenges in China’s extended-range forecast service, and finally proposed the development ideas of future extended-range forecast service.
