Four-hour thunderstorm nowcasting using a deep diffusion model of satellite data

Significance Severe storms threaten human lives and cause substantial economic losses. In this work, we present a storm nowcasting system based on satellite data and AI techniques. It extends forecasts up to 4 h in advance, providing more accurate and detailed predictions of storm growth and decay. Its potential for global application offers an effective means to enhance preparedness and reduce the impact of severe storms worldwide.
