A team of scientists led by CMCC has developed a prediction system for European heatwaves that can provide valuable information 4 to 7 weeks before summer, improving preparedness. The machine learning system, trained on centuries of climate data, has increased forecast efficiency and reduced computational resources needed. This study, published in Nature Communications Earth & Environment, showcases CMCC's leadership in integrating AI with climate science to address heatwaves. Machine learning and AI techniques are revolutionizing climate science by enabling more accurate predictions, offering an alternative to traditional dynamical forecasting systems, particularly in northern European regions.
