2024年多源融合实况分析产品研发进展及在高影响天气和灾害过程的应用与检验
Advancements of Multi-Source Merged Real-Time Analysis Products in 2024 and Their Applications and Verifications in High-Impact Weather and Disaster Events
摘要
Abstract
Advancements of multi-source merged real-time analysis products developed by National Meteorological Information Centre(NMIC)in 2024 are summarized,with the focus on their capabilities to describe high-impact weather processes and applications in meteorological services for disaster prevention and mitigation.The NMIC has achieved a series of key technology breakthroughs in real-time analysis,such as 4DEnVar and weakly coupled assimilation of atmospheric chemistry,and developed 48 products,including the CMA-RA V1.5.The highest spatiotemporal resolution of the products has been enhanced to 10 km and 1 h globally,1 km and 5 min in China,and 100 m and 5 min in local areas,providing stronger support for weather,climate,and weather modification operations.The NMIC has continuously strengthened the application capabilities of multi-source merged real-time analysis products in high-impact weather processes,providing accurate and detailed data support for high-impact weather monitoring.To support the needs from meteorological services for disaster prevention and mitigation,NMIC has established operational gridded data interpolation complement process based on multi-source merged real-time analysis products.As of October 2024,this operational process has provided data interpolation services to 1214 stations with short-term missing data during 17 processes of meteorological disasters and supports in 13 provinces,providing data support to the front-line forecasters in analyzing weather situations.关键词
