Enterprise AI Analysis

A regional artificial intelligence model for skillful typhoon prediction

This research introduces the Hybrid Intelligent Typhoon System (HITS), a regional AI forecasting framework designed for 0-120 hour typhoon prediction over the Asia-Pacific region. Trained on a 9-km high-resolution typhoon reanalysis dataset, HITS combines regional autoregressive prediction with large-scale constraints from the ECMWF Artificial Intelligence Forecasting System (AIFS). A key innovation is HITS-LPIPS, which uses a structure-aware perceptual training strategy to improve the representation of convective and typhoon rainband structures. Experiments demonstrate that HITS-LPIPS significantly reduces typhoon intensity errors (up to 48.3% compared to AIFS at 120 hours) and produces a near-unbiased wind-pressure relationship. This hybrid approach offers a promising pathway for improving natural hazard prediction by integrating high-resolution initial conditions with large-scale circulation constraints.

Executive Impact & Key Metrics

The HITS model represents a significant leap forward in regional typhoon forecasting. By leveraging AI to process high-resolution data and integrate global model insights, enterprises can anticipate more accurate and timely warnings for tropical cyclones. This directly translates to enhanced preparedness, reduced economic losses, and improved safety for populations in affected regions. The model’s ability to predict mesoscale structures and intensity with greater precision allows for more targeted resource deployment and disaster mitigation strategies, offering a substantial competitive advantage in risk management.

42 Hours Short-range forecasts are primarily controlled by initial conditions, crucial for early impact assessment.
120 Hours Longer-range forecasts depend more strongly on large-scale circulation guidance for sustained skill.
Model Key Strengths Limitations
HITS-LPIPS
  • Significantly reduced RMSE across most variables and lead times.
  • Improved precipitation structures and typhoon intensity.
  • Near-unbiased wind-pressure relationship.
  • Still underestimates strongest typhoons.
  • Lower performance at 250 hPa compared to AIFS.
HITS
  • Markedly lower RMSE than CTL.
  • Effective anchoring of synoptic-scale circulation.
  • Structures appear smoother than HITS-LPIPS.
CTL (Baseline Regional AI)
  • Good for short-range (up to ~18h) due to high-resolution initial conditions.
  • Rapid error accumulation in long-time forecasts.
  • Suffers from pronounced error accumulation.
ISTM (Downscaling AI)
  • Better overall than AIFS for surface variables (lead-time dependent).
  • Better short-range performance than CTL after ~42h.
  • Underestimates convection intensity and spatial extent.
  • Predicted fine-scale structures appear overly diffused.
AIFS (ECMWF AI)
  • Strong large-scale prediction capability, especially at 250 hPa.
  • Larger intensity forecast errors across all lead times.
  • Systematically underestimates typhoon intensity.
2x Skill HITS-LPIPS shows more than twice the skill of other models for extreme precipitation (>40 dBZ reflectivity).
Structure-Aware Loss LPIPS perceptual constraint improves realism of convective organization and precipitation morphology.

Extreme Summer Convective Event (China, Aug 2025)

Problem: Accurate prediction of intense convective cores and banded precipitation structures is challenging for traditional AI models.

Solution: HITS-LPIPS, with its hybrid framework and structure-aware training, was applied to this event.

Results: HITS-LPIPS successfully reproduced isolated convective cells and clustered distribution characteristics with strong spatial continuity, outperforming other models which produced smoother or diffused structures. CTL suffered from location shifts, and ISTM underestimated intensity and extent. This demonstrates HITS-LPIPS's superior capability for high-reflectivity precipitation prediction.

300 km Average track error at 120-hour lead time, demonstrating high track forecast skill.
0.04 m/s Near-unbiased wind-pressure relationship achieved by HITS-LPIPS, improving physical consistency.

Typhoon Danas (2025) & Super Typhoon Ragasa (2025)

Problem: Accurate prediction of typhoon position, structural features (rainbands), and intensity, especially for extreme events.

Solution: HITS-LPIPS, HITS, CTL, ISTM, and AIFS were compared in forecasting these typhoons.

Results: HITS-LPIPS provided more accurate predictions of typhoon position and structural features, reproducing isolated convective cells within outer spiral rainbands. Other models produced overly smooth or random rainband details. HITS-LPIPS produced the strongest intensity forecasts, though still underestimating extreme intensity by 10-15 m/s, attributed to training data limitations. All models showed comparable track skill, except CTL.
