Abstract

The invention discloses a magnetic storm prediction method and device based on multi-modal representation learning and a storage medium. The method comprises the steps that satellite magnetic survey data and solar high-energy particle data are input through an input module; the extraction module extracts a first feature of the satellite magnetic survey data; a second feature of the solar high-energy particle data is extracted; geomagnetic discrimination features are extracted according to the first features and the second features; a geomagnetic index is obtained according to geomagnetic discrimination feature classification; the complementarity of the first feature and the second feature is utilized to eliminate the redundancy of the first feature and the second feature, so as to learn better feature representation, improve the classification accuracy and further improve the magnetic storm prediction effect.

Description

technical field [0001] The invention relates to the field of geomagnetic prediction, in particular to a magnetic storm prediction method, device and storage medium based on multimodal representation learning. Background technique [0002] Geomagnetic storms are mainly caused by solar flares that radiate a large amount of high-energy particle streams such as ultraviolet rays and X-rays, and reach the earth to seriously interfere with the earth's magnetic field. The occurrence of geomagnetic storms will cause major power outages, interfere with the operation of radio communications and satellites, as well as aviation navigation and positioning, so the prediction of geomagnetic storms has very important scientific and economic significance. Due to the complex relationship between the occurrence of geomagnetic storms and many factors, if the prediction of geomagnetic storms is only based on one of the factors, it will easily lead to deviations in the results.
