摘要： 随着大城市的不断发展和社会对于气象精细化要求的提高，临近预报特别是突发性灾害天气的临近预报已经成为了社会关注的重点。为了提升短临预报能力，沈阳市气象局先后引进了ANC和TRACER系统，但是由于使用时间较短，之前还没有总结出对于2个系统预报产品的订正技术。本研究通过2013年10月10日与2014年8月24日沈阳2次大雨到暴雨天气过程，总结出ANC和TRACER在短临预报中的不同，ANC的优势更侧重于局地性的强对流天气的预报，而TRACER更有利于相对大范围的、连续性的降水预报。希望研究结果能够给预报员利用ANC和TRACER制作沈阳地区精细化预报预提供订正方法和依据。

Abstract: With the development of big cities and the requirement of society for refined weather forecast, weather nowcasting, especially nowcasting of sudden disaster weather, has become the focus of social attention. In order to improve the nowcasting ability, the Shenyang Meteorological Bureau has introduced ANC and TRACER system. But due to the short time of practical use, correction technology of the two systems has not been summed up. This paper studied the rainstorm weather processes of October 10, 2013 and August 24, 2014 in Shenyang, summarized the differences of ANC and TRACER in nowcasting, and pointed out that the advantage of ANC was more obvious in local strong convection weather forecast and TRACER was more conducive to the continuous and relatively large range precipitation forecast. This paper could provide correction methods and basis for refined weather forecast in Shenyang with ANC and TRACER.
