dividing the meteorological data in the meteorological data analysis subsystem into multiple levels of meteorological early warnings according to the degree of emergency, wherein the higher the degree of emergency is, the lower the level corresponding to the meteorological early warning is;
receiving personnel with different receiving management authorities are configured for the meteorological data corresponding to the meteorological early warnings of different levels, and the meteorological data with low level corresponding to the meteorological early warnings of different levels are pushed to the receiving personnel with high receiving management authorities.
