摘要
融合临近预报系统是预报业务中将雷达回波外推和高分辨率数值模式等多种临近预报系统结合起来生成预报产品的预报系统。文章介绍了国内外几个主要的融合临近预报系统,包括其所采用的外推预报系统、数值预报系统、融合技术以及各融合临近预报系统的优点及其局限性。在此基础上设计了一个简单的融合预报系统进行个例试验,探讨了可能存在的问题及发展方向。
The blending nowcasting system integrates multiple forecast systems, including radar echo extrapolation, high resolution numerical weather prediction, et al. The mainly operational blending now- casting systems in the world were introduced in this paper. The contents include the blending compo- nents, blending technique and the advantages and disadvantages of each system. A simple blending now- casting system was designed and tested to discuss the existing problems and future research directions.
