Engineering Contradiction Analysis
1Reliability
If conventional physics-based numerical simulation is used for weather forecasting, then the forecasting system can simulate atmospheric conditions, but it consumes large amounts of computational power and is exceptionally sensitive to initialization errors
Solution Approach 1:
The patent replaces the conventional physics-based numerical simulation system with an artificial intelligence-based system that uses machine learning models. This substitution eliminates the need for complex computational physics simulations while maintaining or improving forecast accuracy through pattern recognition in historical and real-time weather data.
Solution Approach 2:
The patent transforms the forecasting approach by changing from physics-based parameters to data-driven parameters. The AI system processes multiple data sources including satellite imagery, radar data, and historical weather patterns, converting them into predictive parameters that feed into the machine learning models, thereby reducing sensitivity to initialization errors.
2Measurement precision
If conventional physics-based numerical simulation is used for weather forecasting, then the forecasting system can simulate atmospheric conditions, but it is exceptionally sensitive to initialization errors (imprecision in measurement of initial conditions)
Solution Approach 1:
The patent implements data assimilation processes that perform preliminary actions to clean, validate, and harmonize input data from multiple sources before feeding it into the forecasting model. This preliminary processing reduces initialization errors by pre-correcting inconsistencies and improving the quality of input data.
Solution Approach 2:
The system incorporates feedback mechanisms where forecast outputs are continuously compared with actual observed weather data. This feedback loop allows the AI model to learn from errors and continuously improve its predictions, reducing sensitivity to initialization errors over time through adaptive learning.
3Productivity
If conventional weather forecasting systems are used, then they can provide weather predictions, but they lack the ability to quickly forecast weather which a given business values at a certain point in time
Solution Approach 1:
The patent implements a dynamic forecasting system where the AI model can adjust its processing speed and detail level based on user needs and computational resources. The system can quickly provide general forecasts when speed is prioritized or generate more detailed customized forecasts when accuracy for specific business needs is prioritized, making the system adaptable to different operational requirements.
