Special Issue Information

Dear Colleagues,

Climate change is anticipated to have a profound impact on precipitation patterns worldwide. Regions already susceptible to heavy rainfall may face more frequent and severe flooding, while those accustomed to snowfall might encounter intensified and prolonged snowstorms. Moreover, alterations in atmospheric circulation patterns due to climate change could disrupt the distribution and timing of precipitation, potentially exacerbating drought conditions in certain areas and leading to shifts in seasonal precipitation patterns. These changes may carry extensive implications for water resource management, infrastructure resilience, ecosystem dynamics, and community vulnerability. Hence, this Special Issue endeavors to explore the intricate relationship between extreme precipitation events and the broader context of climate change. Topics of interest include extreme precipitation analysis, joint-probabilistic risks of compound events, climate model downscaling, bias correction of precipitation data, hydrological impacts of climate change, and other relevant topics. By delving into these themes, this Special Issue aims to advance our comprehension of extreme precipitation events within the framework of climate change, fostering interdisciplinary dialog among researchers, policymakers, and practitioners to address these pressing concerns.

Against the background of intensifying global climate change, extreme precipitation events have become increasingly frequent. Improving the accuracy of short-term precipitation nowcasting is therefore essential for disaster prevention and mitigation. Traditional numerical weather prediction (NWP) approaches are constrained by computational latency and errors arising from physical parameterizations, making it difficult to satisfy real-time forecasting requirements at high spatiotemporal resolution. Using the SEVIR dataset, this study conducts a systematic comparison of two Transformer-based deep learning models—Earthformer and LLMDiff—for short-term extreme precipitation nowcasting. Model performance is evaluated using the Critical Success Index (CSI), Probability of Detection (POD), and Success Ratio (SUCR). Results indicate that, for 0–30 min lead times, Earthformer more efficiently captures both local and long-range spatiotemporal dependencies via its Cuboid Attention mechanism and shows a slight advantage for low-intensity precipitation. As the lead time extends to 60 min, LLMDiff demonstrates stronger longer-horizon skill due to its diffusion-based probabilistic modeling and a frozen large language model (LLM) module, which enhance the representation of uncertainty and longer-term evolution of precipitation systems. However, LLMDiff tends to produce a higher false-alarm rate. Overall, Earthformer is better suited for rapid early warning of light precipitation, whereas LLMDiff is more appropriate for high-accuracy nowcasting of heavy precipitation, offering useful insights for intelligent forecasting of extreme weather.
