description The invention provides a multi-parameter space-time meteorological field simulating method and device. According to the method, a preset model database is established in advance and is obtained in the manner that the principle component analysis is carried out based on multi-site and multi-parameter historical meteorological data, frequency division is carried out on all generated main component sequences to obtain a plurality of intrinsic mode function sequences, segmentation is carried out on the intrinsic mode function sequences to form composition sheets, and the composition sheets are simulated, and therefore the preset model database can fuse a plurality of parameters of the historical meteorological data and can represent the rule of the historical meteorological data. A target time quantum needing to be simulated and a solar altitude angle set are input into the preset model database, the preset model database carries out simulation according to the existing historical meteorological data, and a simulated multi-site and multi-parameter meteorological matrix is obtained. The future meteorological field can be reasonably assessed, a technological support is provided for the environmental risk analysis subject, and assessing of one reasonable extreme scene becomes possible.
