Abstract
Description
Technical Field
[0001] This invention relates to the field of typhoon path prediction technology, and in particular to a method, system, terminal, and computer-readable storage medium for typhoon path prediction based on multimodal data from radiosonde equipment and the Pangoal Injection Model. Background Technology
[0002] Significant bottlenecks exist in typhoon track prediction. Its core reliance on supercomputers to solve complex atmospheric dynamic equations results in single predictions taking hours or even days, failing to meet the demands for real-time typhoon monitoring and rapid response. Furthermore, numerical models, due to simplified physical processes (such as ignoring small-scale ocean turbulence and local wind field variations), lack the ability to model complex meteorological phenomena like abrupt typhoon track changes and multiple typhoon interactions, leading to significant prediction errors. More critically, data assimilation mechanisms (the temporal and spatial unification of data from aerostats (irregular trajectories), satellites (gridized), and radars (polar coordinates)) are inefficient, primarily relying on satellite and ground station data. They fail to effectively integrate upper-air three-dimensional meteorological data (such as vertical wind speed profiles and temperature and humidity gradients) collected by aerostats and drop equipment, limiting the accuracy of the initial field and further impacting prediction reliability.
[0003] While deep learning-based prediction methods have achieved breakthroughs in computational speed, their limitations are equally prominent. Existing methods largely rely on two-dimensional neural networks to process historical meteorological data, lacking the ability to model three-dimensional atmospheric structures (such as vertical wind shear in the typhoon eye) and failing to incorporate physical constraints (such as energy conservation equations). This results in poor stability of predictions under extreme weather scenarios (such as typhoon reversals). Furthermore, these models fail to fully integrate multimodal data; satellite remote sensing, real-time observations from aerostats, and high-altitude data from drop equipment are isolated, resulting in insufficient ability to capture detailed local features. In addition, model training depends on historical datasets, leading to a lag in response to sudden meteorological events. Moreover, the "black box" nature of these models (poor interpretability of AI algorithms) makes the prediction results uninterpretable, hindering the reliability of disaster prevention decisions.
[0004] While existing large-scale meteorological model forecasting methods perform well in global weather forecasting, they still have shortcomings in specific applications for typhoon tracks. Despite employing a 3D neural network architecture, actual data input still primarily relies on satellite and ground-based data; real-time 3D observation data from aerostat-deployed equipment is not deeply integrated, resulting in insufficient capture of upper-level dynamic characteristics in the typhoon core area. Furthermore, large-scale models require cloud deployment, making it difficult to adapt to the real-time inference needs of edge devices such as aerostats, and hindering data closed-loop optimization of the typhoon core area. In complex scenarios (such as multiple typhoon interactions and coastal topographic effects), the lack of dynamic input from multimodal data such as ocean thermal and topographic disturbances significantly reduces generalization ability and increases prediction error fluctuations. These shortcomings collectively limit the practical effectiveness of large-scale meteorological models in accurate typhoon track forecasting.
[0005] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0045] This invention acquires low-resolution data of the typhoon core area through the Pangu meteorological model, integrates real-time observation data from multiple sources such as satellites and drones, and generates a high-resolution field through spatiotemporal interpolation and Diffusion Model. Then, it uses a cascaded AI downscaling network combined with physical constraint correction for fine modeling. Finally, it uses graph neural networks and deep reinforcement learning to quantify the interaction between the typhoon and the environment and outputs a path forecast with confidence intervals and a thermodynamic structure analysis report, thus achieving accurate typhoon prediction.
[0046] The typhoon path prediction method based on multimodal data from radiosonde equipment and the Pangoal-Rayet model, as described in the preferred embodiment of the present invention, is as follows: Figure 1 and Figure 2 As shown, the typhoon path prediction method based on multimodal data from radiosonde equipment and the Pangoal Institutional Array (PANGU) model includes the following steps:
[0047] Step S10: Acquire multi-source heterogeneous data collected by detection equipment related to typhoon forecasting, and fuse and adaptively enhance the multi-source heterogeneous data based on the Pangu meteorological big model to generate a high-resolution three-dimensional field.
[0048] Specifically, the global forecast data stream of the Pangu meteorological model is accessed, and low-resolution grid data (0.25° accuracy) of the typhoon core area is extracted. The low-resolution grid data includes pressure field, three-dimensional wind field, humidity field and sea surface temperature field.
[0049] A typhoon feature space is constructed based on a historical typhoon database (which consists of low-resolution grid data of the core area of historical typhoons). The typhoon feature space is a high-dimensional data space constructed by extracting key meteorological parameters (such as air pressure, wind speed, temperature, and typhoon structure characteristics) from historical typhoon data. The current typhoon type (such as super typhoon or double-walled typhoon) is identified by clustering algorithms, and key prediction areas are dynamically delineated (e.g., adjustable radius of 300-800 kilometers).
[0050] The observation data from the detection equipment will be synchronized. The observation data from the detection equipment includes: temperature profile data of the typhoon eye area collected by the Advanced Microwave Scanning Radiometer 2 (AMSR-2), three-dimensional wind speed field collected by UAV-borne millimeter-wave radar (e.g., 10-meter resolution three-dimensional wind speed field of UAV-borne millimeter-wave radar), sea surface temperature and air pressure data collected by ocean buoys (SST), and upper-air three-dimensional meteorological data (e.g., vertical wind speed profile, temperature, humidity and pressure) collected by airships.
[0051] Design a spatiotemporal alignment algorithm: Use spatiotemporal kriging interpolation to map point observation data (referring to local meteorological data collected by the above detection equipment, which is called point observation data because the spatial and temporal ranges are not very continuous) onto the Pangu meteorological model. Establish nested high-resolution subgrids (0.01° accuracy) for the typhoon eye area (e.g., radius 50 km) to improve the modeling accuracy of the typhoon core area (0.25°->0.01°, approximately 25km->1km).
[0052] A typhoon data generator based on a diffusion model is constructed. Low-resolution grid data and observation data from detection equipment (i.e., sparse observation data) are input into the typhoon data generator for fusion processing, and a complete high-resolution (0.05°) three-dimensional field of temperature, pressure, and humidity in the typhoon eye region is output. The loss function combines Wasserstein distance and physical conservation constraints (such as the mass conservation equation). In the typhoon data generator, the loss function is the core mechanism driving model learning and optimization.
[0053] Deploy an anomaly detection module that uses an autoencoder to identify and remove noise data observed by detection devices (including satellite microwave imagers, drones, ocean buoys, and airships).
[0054] The adaptive enhancement of this invention refers to the intelligent repair, supplementation and optimization of multi-source meteorological data through AI algorithms to improve the integrity, resolution and reliability of the data.
[0055] Step S20: Construct a cascaded AI downscaling network, introduce a physical constraint layer, perform local fine modeling of the typhoon eye region based on the high-resolution three-dimensional field, and output a high-resolution three-dimensional meteorological field.
[0056] Specifically, a cascaded AI downscaling network is constructed, which includes a computer vision model (Vision Transformer) and a three-dimensional convolutional neural network (3D-CNN). The computer vision model is used to extract global meteorological features (such as cyclonic vorticity fields) output by the Pangoal Meteorological Model and input them into the three-dimensional convolutional neural network. The three-dimensional convolutional neural network is used to perform local fine-grained modeling of the typhoon eye area. Based on the input satellite infrared cloud image and a database of historical similar typhoon cases, it outputs a three-dimensional meteorological field (e.g., a three-dimensional meteorological field with a resolution of 0.05°) covering the typhoon core area (e.g., a radius of 200 kilometers).
[0057] A lightweight LSTM-ENKF hybrid assimilation algorithm was developed. LSTM (Long Short-Term Memory) was used to predict the systematic bias distribution of the Pangu meteorological model, quantifying the spatial distribution of model errors and providing a clear correction direction for data assimilation. This enhanced the downscaling model's ability to capture complex meteorological characteristics of the typhoon core area, supporting accurate prediction. An ensemble Kalman filter (ENKF) was used to dynamically inject UAV observation data into the cascaded AI downscaling network, outputting a high-resolution three-dimensional meteorological field after data assimilation and physical constraint correction.
[0058] A physical constraint layer is introduced, and a partial differential equation (PDE) verification module is added to the output of the cascaded AI downscaling network to ensure that the predicted field conforms to the fluid dynamics equations.
[0059] Step S30: Design a typhoon-environmental field interaction model based on graph neural network, perform typhoon prediction based on the high-resolution three-dimensional meteorological field, and output a typhoon path set forecast containing confidence intervals and a typhoon thermodynamic structure analysis report.
[0060] Specifically, a typhoon-environmental field interaction model based on graph neural networks is designed. The typhoon structure (the physical components and dynamic relationships within a typhoon, represented by nodes and edges) is abstracted into a dynamic graph. Environmental field data is input to predict the probability distribution of the typhoon's movement direction.
[0061] A deep reinforcement learning policy optimizer is constructed, which uses the historical typhoon track fit and physical rationality score as the reward function to output a set of typhoon track forecasts containing confidence intervals within a preset time (e.g., 72 hours).
[0062] A multi-task learning architecture was developed, with the main task being to predict the maximum sustained wind (MSW) and the minimum central pressure (CP) at the typhoon center, and the auxiliary task being to identify signs of abrupt changes in intensity (such as eyewall replacement events).
[0063] It integrates interpretable AI components and uses the Spatial SHAP algorithm (Spatial Shapley AdditiveExplanations, an extended method based on SHAP values specifically used to interpret spatial data or models with spatial structures (such as remote sensing images, geographic information systems / GIS, weather forecasts, urban planning, etc.)) to visualize key areas of influence intensity, generating a typhoon thermodynamic structure analysis report (PDF format) with annotations of physical parameters such as warm core height, outflow layer intensity, vertical temperature lapse rate, specific humidity, tangential wind, and radial wind.
[0064] Furthermore, the TinyML architecture (Tiny Machine Learning, a machine learning technology for ultra-low power, micro-embedded devices, designed to deploy AI models on resource-constrained edge devices (such as MCUs, sensors, and IoT devices) is deployed on the detection equipment to achieve "edge intelligence." Knowledge distillation is performed on the cascaded AI downscaling network (teacher network: large cloud model; student network: binarized CNN). Through hardware optimization, the meteorological data preprocessing process is standardized and modularized, enabling it to automatically execute multiple preprocessing steps in a fixed sequence, like an industrial assembly line, to improve data processing efficiency and reduce power consumption. For example, using FPGA to implement the meteorological data preprocessing pipeline reduces power consumption by 42% (actual measured data).
[0065] Key indicators of the eye structure (such as the eyewall gradient wind speed ratio) are uploaded to the cloud server at set intervals (e.g., every 5 minutes) to support dynamic model optimization and prediction result generation in the cloud, and the prediction results are displayed on the visualization platform.
[0066] Construct an online incremental learning framework: Data layer: Streaming real-time observation data streams (Kafka pipeline) to perform continuous, unbounded data processing on meteorological data (such as wind speed, temperature, humidity, radar echoes, etc.) collected in real time by typhoon monitoring equipment (such as drones, radiosondes); Model layer: Employing the Elastic Weight Consolidation (EWC) algorithm to prevent catastrophic forgetting, mainly through a "parameter importance weighted constraint" mechanism to constrain the update magnitude of model parameters and prevent the forgetting of key features of historical typhoon samples during new data training.
[0067] Update strategy: Obtain the prediction error of the typhoon forecast. When the prediction error exceeds a threshold (e.g., path deviation > 50 km / 6 hours), trigger the Pangu meteorological model to perform model fine-tuning.
[0068] The technical effects that this invention can bring are as follows:
[0069] (1) Speed improvement: The typhoon prediction time has been shortened from 5 hours in the traditional numerical model to 10 seconds.
[0070] (2) Improved accuracy: Typhoon path prediction error is reduced by 20%-30%, supporting complex abrupt path modeling.
[0071] (3) Resource saving: The computing power requirement is only 1 / 1000 of that of traditional methods, which is suitable for the deployment of edge computing devices.
[0072] Furthermore, such as Figure 3 As shown, based on the above-mentioned typhoon path prediction method using multimodal data from radiosonde equipment and the Pangoal-King model, this invention also provides a typhoon path prediction system based on multimodal data from radiosonde equipment and the Pangoal-King model. The typhoon path prediction system based on multimodal data from radiosonde equipment and the Pangoal-King model includes:
[0073] The multi-source heterogeneous data fusion and adaptive enhancement module 51 is used to acquire multi-source heterogeneous data collected by detection equipment related to typhoon prediction, and to fuse and adaptively enhance the multi-source heterogeneous data based on the Pangu meteorological big model to generate a high-resolution three-dimensional field.
[0074] The dynamic downscaling and physical constraint correction module 52 is used to construct a cascaded AI downscaling network, introduce a physical constraint layer, perform local fine modeling of the typhoon eye area based on the high-resolution three-dimensional field, and output a high-resolution three-dimensional meteorological field.
[0075] The multimodal typhoon evolution prediction and report generation module 53 is used to design a typhoon-environmental field interaction model based on graph neural networks, perform typhoon prediction based on the high-resolution three-dimensional meteorological field, and output a typhoon path set forecast containing confidence intervals and a typhoon thermodynamic structure analysis report.
[0076] Furthermore, such as Figure 4 As shown, based on the above-mentioned typhoon path prediction method and system based on multimodal data from radiosonde equipment and the Pangoal Institutional Array (PANGU) model, the present invention also provides a terminal, which includes a processor 10, a memory 20 and a display 30. Figure 4 Only some of the terminal components are shown; however, it should be understood that it is not required to implement all of the components shown, and more or fewer components may be implemented instead.

Further, the memory 20 may include both internal and external storage devices. The memory 20 is used to store application software and various types of data installed on the terminal, such as the program code installed on the terminal. The memory 20 can also be used to temporarily store data that has been output or will be output. In one embodiment, the memory 20 stores a typhoon path prediction program 40 based on multimodal data from a radiosonde and the Pangoal Mechanism model. This typhoon path prediction program 40 based on multimodal data from a radiosonde and the Pangoal Mechanism model can be executed by the processor 10, thereby implementing the typhoon path prediction method based on multimodal data from a radiosonde and the Pangoal Mechanism model in this application.
[0078] In some embodiments, the processor 10 may be a central processing unit (CPU), a microprocessor, or other data processing chip, used to run program code stored in the memory 20 or process data, such as executing the typhoon path prediction method based on multimodal data from radiosonde equipment and the Pangu model.
[0079] In some embodiments, the display 30 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, or an OLED (Organic Light-Emitting Diode) touchscreen. The display 30 is used to display information on the terminal and to display a visual user interface. The terminal's processor 10, memory 20, and display 30 communicate with each other via a system bus.
[0080] In one embodiment, when the processor 10 executes the typhoon path prediction program 40 based on multimodal data from radiosonde devices and the Pangoal Mechanism model stored in the memory 20, the following steps are performed:
