Abstract

The invention relates to a meteorological proximity prediction method and device, computer equipment and a storage medium. The computer equipment acquires a radar echo map of a target area; then, inputting the radar echo map into a proximity prediction model to obtain meteorological proximity prediction data of the target area; wherein the proximity prediction model is obtained by carrying out migration training on a base model according to a region sample set of a target region; wherein the base model is obtained through training by adopting a meta-learning mechanism and a universal sample set; wherein both the regional sample set and the universal sample set comprise historical radar echo maps and proximity prediction results corresponding to the historical radar echo maps. By adopting the method, the accuracy of meteorological proximity prediction can be improved, and the quick learning ability of a proximity prediction model can be improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a weather nowcasting method, device, computer equipment and storage medium. Background technique [0002] With the development of deep learning technology, artificial intelligence (AI) weather nowcasting has become a research hotspot. However, the meteorological observation data in different regions are mainly collected by scattered radars in different regions. Due to the huge climate differences in different regions, The distribution of radar echo patterns in different regions is quite different, which is still extremely challenging for the use of artificial intelligence in weather nowcasting. [0003] In the traditional method, computer equipment conducts model training on the historical radar echo images of different regions, obtains the nowcasting model of the region, and performs meteorological nowcasting of the region according to the model.
