文章介绍了1989年夏季在长江三角洲地区进行的强对流天气业务预报试验中基地中心的系统硬件设置,加密观测站网,GMS卫星实时接收和图像处理系统,数字化雷达站网,短时预报中心工作站及产品,短时预报业务工作流程,预报技巧评分等。通过与中心气象台互封闭式地作预报结果的比较和一些实例分析,指出建立VSRF系统后对强对流天气的预瞥水平有明显的提高。并超过美国PROFS 1983年的水平。 相似文献

The real time operational severe convective weather forecast experiment carried out during May to July in 1990 over the Changjiang Delta is briefly described. The heavy rainfall and severe conveetive weather forecast worksheets for the Changjiang Delta have been proposed and used in the daily forecasting. Results show that the ability of 0-12h convective weather prediction has been improved significantly after the development of the forecast methods and the establishment of a mesoscale forecast base at Shanghai Meteorological Center during 1986 to 1990.Three cases of convective weather systems (meso-alpha, meso-beta, meso-gamma) during the experiment period are described and discussed. 相似文献
