中文摘要: 建立无缝隙集约化的天气预报业务体系,需要进一步加强中短期天气预报业务技术的发展。通过对现状回顾,指出经过2011—2015年的气象现代化建设,在我国国家级和部分省级业务单位已初步建立了数字化中短期业务预报技术流程,其包括数值模式系统、客观方法释用、预报主观编辑制作以及精细化格点后处理四个方面。但与国外发达国家相比,我国中短期业务技术还存在数值模式发展水平不高、客观预报技术方法未全面深入开展、缺乏有效技术工具支撑预报员进行订正、格点化的处理技术基础薄弱等问题。文章在发展现状和问题分析的基础上,提出未来应提高自主数值模式系统的基础支撑作用,深入发展海量预报信息的客观提取及订正技术,加强开发主观和客观融合的技术和工具平台,完善精细化的格点处理技术的发展思路,并进行具体阐述。最后,从技术发展的基础数据支持、路线选择、发展规律以及交流共享四个方面提出参考意见。
Abstract:Operational technologies in short and medium range weather forecast need further strengthening for the development of seamless and intensified weather forecast operational framework. Through reviewing present status of development, we find that, by the meteorological modernization during 2011-2015, the preliminary digitization for the technical flow in the short and medium range operational forecast has been developed in the national and some provincial operational units of China, including the numerical weather prediction system, the objective method application, the subjective editing and the downscaling gridded post processing. However, comparison with the developed countries shows that there are still some problems in the short and medium range operational technologies of China, such as lower level development of numerical model, insufficiency of complete and in depth application of the objective technical method, lack of effective technology tools to support calibration of forecasters and the weak foundation of processing technique for gridding. Based on the review of present status of development and the analysis of current problems, suggestions are made that in the future development, the foundation role of the independent numerical model system should be enhanced, the objective techniques of forecast information extraction and calibration should be further developed, platform of subjective and objective blending techniques and tools should be developed greatly, and the development concepts of the downscaling gridded processing technique should be improved, followed by detailed exposition. Finally, ideas for reference are provided on four aspects, which are the basic data support for technical development, selection of the technical route, laws of technical development as well as exchange and sharing of techniques.
