The application relates to the field of wind field prediction, and discloses a low-altitude wind field prediction system and method based on a sea-land wind model, which comprises the following steps: obtaining wind field records along a coastal observation belt and taking the fine time dislocation formed between different devices as a synchronous reference; layer by layer, energy distribution in the wind field records which changes with height, temperature difference and humidity is split; the change clues of wind field element groups reflecting fluctuation, deflection and weak rotation trend are limitedly coded, the mutual pulling degree of disturbance in each period, the energy transfer direction and the mutation sensitivity are remolded into structured data segments; unstable interaction in local areas in the wind speed, wind direction and vertical temperature difference relationship is found by using a wind field expression body, and the disturbance transmission relationship between nodes in these areas is extracted; and micro-disturbance events are compared with the long-term deviation distribution of the overall observation records. The application has the advantages of improving the capturing and expression ability of micro-scale wind field disturbance.

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.

This application belongs to the field of computer technology. It provides a method, apparatus, electronic device, and storage medium for displaying wind-blowing animation effects. The method includes: receiving a wind-blowing animation effect display instruction, wherein the instruction includes a target animation mode; obtaining a target animation simulation configuration file according to the target animation mode; and controlling a wind model to simulate and display wind-blowing animation effects according to the target animation simulation configuration file. Based on the above method, by using a computer program to execute the animation simulation configuration file to control the wind model used to display wind-blowing animation effects, the display of wind-blowing animation effects can be achieved. This improves the fluidity and dynamism of 3D wind and solves technical problems such as overly regular wind shaping, poor fluidity and dynamism, and rigid wind effects.
