雷达资料同化方法：回顾与前瞻
Radar Data Assimilation Methods: Review and Future Perspective
中文摘要：
自20年前第一个业务天气雷达观测网在美国建立以后，气象界在多普勒天气雷达资料同化方面的研究和应用已取得了显著成果。中国在21世纪初也完成了一个覆盖大多数地区的多普勒天气雷达观测网，在实时监测及预警对流天气、
降水及台风等方面起到了重要作用。但是，中国在同化雷达资料以改进细网格数值模式的初始化精度方面的研究及应用仍然处在起步阶段。对数值模式中同化雷达资料利用方法的研究和应用进行了简短回顾，也对未来该领域研究的重点研究方向提出建议。

Abstract：
Since the first operational Doppler radar network was established in the United States of America in the early 1990’s, significant progress has been made on the research and application of radar data assimilation. China installed its operational Doppler radar network in the early 2000’s, and has widely used for real-time detecting and warning the convective weather, precipitation and tropical cyclone. However, the attempt to assimilate Doppler radar data into numerical weather prediction (NWP) models for the improvement of model initial conditions is just begun. In this paper, we review the past effort and progress on assimilating radar data into NWP models, in order to promote the research and development in this important field.
