Scientists in China created a new model that combines AI and physics to forecast typhoon waves. They tested it on two real-life typhoons and found it improved accuracy by up to 34.9%. This can help save ships, platforms, and coastal infrastructure from damage.
Typhoons are powerful storms in the Pacific Ocean that bring strong winds and huge waves. These waves can be very dangerous for ships, offshore platforms, and coastal areas. But current methods of forecasting typhoon waves often underestimate their height. This can lead to errors in predicting when a storm will hit or how severe it will be.
Researchers in China wanted to improve these forecasts. They created a new model that uses artificial intelligence (AI) and physics to predict wave heights more accurately. The AI part of the model learns from data about past storms, while the physics part helps it understand how waves behave. This combination is called a 'coupled' model.
The researchers tested their new model on two real-life typhoons that hit the East China Sea in 2024. They compared the predicted wave heights with actual measurements taken by buoys and coastal stations. The results showed that the coupled model was more accurate than current methods, reducing errors by up to 34.9%.
The team used two different scenarios to test their model: one where a typhoon is weakening (Test A) and another where it's at its strongest (Test B). In Test A, the hybrid model reduced error by 34.9%, while in Test B, it reduced error by 11.0%. The researchers found that when conditions were different from what the AI had learned about, the physics-guided part of the model helped improve accuracy.
This new model can help save lives and property by providing more accurate forecasts of typhoon waves.
