Meteorological data processing method and system based on system post-processing and drawing module

The invention provides a meteorological data processing method and system based on a system post-processing and drawing module, and the method comprises the steps: converting a numerical mode prediction result from a mode to an isobaric surface in a parallelization mode, and obtaining numerical prediction data; calling an electronic map and coordinate data of the target area; performing background feature extraction on the numerical forecasting data to obtain to-be-processed data; obtaining a data file size and a display size required by the drawing image, and calculating an extraction proportion; extracting feature data from the to-be-processed data according to the extraction proportion, and generating a drawing file in a preset format by using the feature data; importing the drawing file into a drawing module, superposing the electronic map and the coordinate data, and analyzing the drawing file, the electronic map and the coordinate data through a drawing script to obtain drawing parameters and meteorolog
