A Database Engineered System for Accurate Tornado Prediction and Forecasting

Centrala begrepp

A database engineered system that integrates meteorological data and tornado climatology to accurately predict tornado occurrence, magnitude, and location using a recurrent neural network (RNN) model.

Sammanfattning

The paper presents a database engineered system that aims to address the challenges in current tornado warning systems by designing and developing a tornado forecasting system that accounts for geographical and meteorological characteristics. The system utilizes tornado data, meteorological parameters, and advanced machine learning techniques, specifically a recurrent neural network (RNN) model, to create a localized forecasting system capable of providing detailed forecasts, including specific timing, magnitude, and geographical location of tornado events.

The key highlights of the system include:

• A new LSTM-RNN predictive forecasting model with 85.94% cross-validation accuracy
• Active learning for labeling weather data points and dynamically updating when new data arrives
• Classification of new data points to predict tornado occurrence or not
• Implementation of 10-fold cross-validation for multiple training sets to reduce bias in results
• Insights into yearly model accuracy, AUC scores, confusion matrix, and model training accuracy vs. loss

The system leverages the capabilities of the RNN to discern patterns indicative of tornado occurrence based on meteorological data. The RNN's ability to capture temporal dependencies and patterns in the data makes it well-suited for the sequential nature of tornado formation, outperforming other models that treat the data as independent samples.

The evaluation results demonstrate the effectiveness of the database engineered system, with high AUC scores, good accuracy, sensitivity, and precision in predicting tornado events. The system's performance highlights its potential for real-world applications, such as advancing comprehensive information systems for tornado genesis, improving safe evacuation procedures, standardizing prompt warning systems, and providing tornado protection for a broader range of regions.
