Embodiment 1
[0059] Step 101, collecting and sorting historical numerical model products (products of numerical model analysis field) and satellite cloud image data at the same time and in the same area to construct a paired training data set.
[0060] The selected numerical model products are the reanalysis field products with a resolution of 0.25×0.25° in the fine-grid numerical weather forecast products provided by the European Center for Medium-Range Weather Forecasting and the products with a resolution of 4 km from the Fengyun 4A (FY-4A) geostationary meteorological satellite. The coverage of selected products is from 10°N to 50°N, and from 110°E to 150°E. Since the data acquisition of the FY-4A geostationary meteorological satellite started in April 2018, the training data selected hourly data from April 1 to July 20, 2018, totaling more than 2,500 hours of data.
