Artificial intelligence has improved weather forecasting, but it still struggles to predict hurricane intensity. This is because regional forecasts require more detailed data than global datasets can provide.
Artificial intelligence (AI) has revolutionized weather forecasting in just a few years. Global AI weather models can now produce forecasts that rival some of the world's best physics-based prediction systems.
This progress has been driven by three factors: massive amounts of weather data, advances in AI models, and unprecedented computing power. However, when it comes to predicting hurricane intensity, AI faces significant challenges.
Hurricane Polo is a recent example of this challenge. In September 2026, it rapidly intensified from a tropical storm to a powerful Category 5 hurricane in just 24 hours. This rapid intensification surprised forecasters and left communities with too little time to evacuate and prepare.
Unlike global weather forecasts, hurricane intensity forecasts are often considered regional forecasting problems. Regional forecasts focus on extreme events like hurricanes, which can develop rapidly or move quickly over short periods of time. Capturing such behavior in AI models requires data in much greater detail than current global datasets can provide.
When scientists train AI models to predict hurricane intensity, they rely on two sources of data: observations and weather model simulations. Observations include measurements from weather stations, radars, buoys, and satellites. However, these direct observations are often limited to near-coastal regions and unevenly distributed.
Modern satellites can help fill some of the gaps in the open ocean, but they have limitations. They can only estimate part of the rainfall, surface winds, or cloud-top temperatures due to limits in satellite coverage.
Why It Matters
Understanding how AI predicts hurricane intensity is crucial for communities affected by these storms. If AI models can accurately predict rapid intensification, it could save lives and reduce damage.
