Ocean thermohaline prediction method and system

The invention relates to an ocean temperature and salinity prediction method and system, and the method comprises the steps: carrying out the feature extraction of time and space dimensions of ocean temperature and salinity data through a four-dimensional convolution model, further exploring the spatial features of the ocean temperature and salinity through a residual structure, and carrying out the weighting quantification of the contribution degree of each region feature through recalibration. The model quality is improved, and the ocean temperature and salinity prediction is realized. And meanwhile, the prediction result of the ocean temperature and salinity is visually displayed in combination with visual display. According to the invention, through combination of the four-dimensional convolution model, the residual structure and recalibration weighting, double influences of a time sequence and marine internal spatial features on marine temperature and salinity prediction are considered, and limitations o
