Solution Overview
Problem
Current methods for modeling tropical cyclones, such as physics-based modeling and statistical analysis, face challenges in providing accurate predictions for areas with sparse or no historical data, requiring significant computational resources and expert input, and are unreliable without historical data.
Innovation Solution
A machine learning model is trained using an image-based knowledge graph of tropical cyclone data to generate surface wind and rainfall fields from tropical cyclone tracks and pressure intensities, allowing for accurate predictions without relying on historical data or physics-based models.

Engineering Contradiction Analysis
1Measurement precision
If physics-based modeling is used to model tropical cyclone surface fields, then prediction accuracy for areas without historical data is improved, but computational resource consumption increases significantly
Solution Approach 1:
The patent replaces the physics-based computational fluid dynamics model with a machine learning model that uses neural networks to predict tropical cyclone surface fields. This substitution eliminates the need for complex physics calculations while maintaining prediction accuracy, thereby significantly reducing computational resource consumption.
Solution Approach 2:
The patent creates a data-driven representation of tropical cyclone behavior by training machine learning models on available historical data and satellite observations. This copying approach allows the system to predict cyclone surface fields without requiring real-time physics-based calculations, reducing computational burden while maintaining accuracy.
2Measurement precision
If physics-based modeling is used to model tropical cyclone surface fields, then prediction accuracy is improved, but the complexity of the modeling system increases
Solution Approach 1:
The patent replaces complex physics-based modeling systems with machine learning models that learn patterns from data. This substitution simplifies the overall system architecture by eliminating the need for complex atmospheric physics equations and calculations, while maintaining or improving prediction accuracy.
Solution Approach 2:
The patent introduces machine learning models as intermediaries between input data (cyclone tracks, pressure, satellite observations) and output predictions (surface wind and rainfall fields). This intermediary approach simplifies the modeling process by using data-driven relationships rather than complex physical mechanisms.
3Use of energy by moving object
If statistical analysis is used to model tropical cyclone surface fields, then computational resource consumption is reduced, but prediction reliability deteriorates in areas without historical data
Solution Approach 1:
The patent replaces traditional statistical analysis with machine learning models that can generalize from limited data. This substitution enables the system to maintain reliability in data-scarce regions by learning from available observations and applying the learned patterns to predict cyclone surface fields where historical data is sparse or nonexistent.
