China has gradually formed an early warning model of "government-led, warning-triggered, cross-department coordination, and public participation". The Chinese government has formulated a series of laws, regulations, standards, systems, and emergency plans for disaster prevention and mitigation. Through early warning information, governments and relevant departments at all levels are able to carry out meteorological disaster prevention and mitigation measures in an orderly manner. Meanwhile, every effort has been made to promote the national comprehensive risk survey of natural disasters so as to provide authoritative information and scientific decision-making basis for effective implementation of natural disaster prevention and control.
When dealing with major disastrous synoptic processes, CMA assesses the risk of meteorological disasters in advance and, as the synoptic process approaches, keeps updating forecasting and warning services of higher spatiotemporal resolution and accuracy. At the same time, a meteorological disaster risk prediction model has been established based on disaster types, industries, regions, and time periods. Relying on the national emergency warning information release system, the national-, provincial-, city- and county-level early warning hierarchy has been established and 16 different sectors and industries have been connected within the system. 82 types of early warning information can be gathered, shared and sent out in a “one-button” mode. In addition, through customized services and localized deployment, early warning information can be spread out extensively.
China has also created a high-level "call for action" mechanism for early warning, which means that when major disastrous weather is about to or has already occurred and is highly likely to cause a major disaster, CMA will provide "point to point" reminders to government leaders and heads of disaster related departments in advance. Under the emergency coordination mechanism led by meteorological early warning, a refined and detailed classification of early warning response grades has been provided and China has gradually established a mechanism for suspending classes, production activities, operation, and business in high-risk areas and highly sensitive industries under extreme weather conditions. At the same time, a total of nearly 400000 meteorological information personnel have received training and are expected to enter schools, rural areas, enterprises, and communities for the enhanced disaster prevention and mitigation capabilities of the whole society.
