This invention discloses a high-precision typhoon field reconstruction method based on the fusion of physical constraints and data-driven approaches. It uses SHAP values ​​to filter key driving elements from multi-source data, constructs a machine learning model to adaptively invert key structural and shape parameters of empirical typhoon models, generates a physical background wind field, and inputs it into a physically constrained deep learning network to learn the residual components between the background wind field and the true satellite observation values. Finally, the residuals are superimposed to achieve wind field reconstruction. This invention explicitly models the typhoon rotation structure using the WMConv module and employs a hierarchical physical constraint loss function, solving the problems of difficult parameter acquisition in empirical models, large structural biases, and weak physical consistency in purely data-driven methods. It achieves a balance between high precision, high efficiency, and good physical interpretability.
