An artificial intelligence model for sand and dust storm forecast driven by AI weather forecasts
Authors: Jikang Wang & Cong Hua | DOI: https://doi.org/10.1038/s44407-025-00048-z
We present AI-DUST, a deep learning model for dust forecasting directly driven by AI-generated weather forecasts. Integrating a Multiple Stacked Graph Attention Network with physical constraints and a physics-based emission scheme, AI-DUST captures key atmospheric physical processes without relying on traditional numerical dust modeling chains. The model demonstrates exceptional accuracy in reproducing a traditional dust model, with correlations >0.99 (one-step) and >0.61 (80-step). In real-time forecasts of 2025 spring sand and dust storms (SDS) over East Asia, AI-DUST outperformed operational models, achieving a 27% higher Threat Score (TS) in 48-hour predictions across 14 strong events. Its 10-day forecast TS exceeds 0.22, demonstrating strong long-term capability. The model generalizes well to unseen regions like the Sahara, enabled by its architecture and standardized preprocessing. This work demonstrates the feasibility of building atmospheric environmental forecasting systems directly driven by AI-generated weather forecasts, paving the way for new, efficient AI-driven chemistry and transport models.

Forecasting Severe Dust Events & Meteorological Sensitivity
AI-DUST showcased exceptional skill during the Spring 2025 SDS events in East Asia, accurately predicting 14 widespread events. Notably, for the unprecedented April 10-14 event reaching Southern China, AI-DUST achieved a domain-averaged TS of 0.75 and maintained high temporal correlation (R > 0.8) and low relative error (RE < ±50%) across affected regions. The model's performance is highly sensitive to meteorological inputs; when driven by AIFS forecasts and high-resolution surface characteristics, it consistently achieves the highest Threat Scores, demonstrating the synergy between advanced AI weather forecasts and dust modeling.
Zero-Shot Forecasting in Unseen Global Regions
AI-DUST demonstrates remarkable generalization capabilities beyond its training domain. In zero-shot forecasting experiments for the Sahara and Arabian Peninsula, the model accurately reproduced the spatial extent and location of intense SDS activity on March 22 and May 12, 2025. This cross-regional success confirms that AI-DUST has learned fundamental physical patterns of dust dynamics, making it a globally applicable and portable tool for SDS forecasting, even in regions with no prior training data.
