Performance Tests and Evaluations of Beijing Local High-resolution Rapid Update Cycle(RUC) System 北京地区高分辨率快速循环同化预报系统性能检验和评估
Results as follows : ( 1 ) based on WRF model, the four dimension data assimilation, rapid update cycle and analog-based Kalman filter bias correction technology are applied to the numerical weather forecast platform and built the numerical weather forecast platform. 得到以下结论:(1)基于WRF模式,将实时四维数据同化、快速更新循环模拟技术应用于风电功率预测的数值天气预报业务平台,采用类比卡曼滤波误差订正技术对预报序列进行误差订正。
Meanwhile, the high-tech rapid development, product update cycle is short, and generally showed high growth trend. 同时,高新技术发展快、产品更新周期短,且一般呈高速增长的态势。
With the rapid development of modern information technology and knowledge economy, the update cycle of knowledge is greatly shortened, the speed is continuously accelerated, change and innovation has become the subject of social and economic life. 随着现代信息技术和知识经济的迅速发展,知识更新的周期明显缩短,速度不断加快,变革与创新已成为社会经济生活的主题。
Rapid design has been proposed and developed owing to the demand of products diversity and rapid update, and it refers to all the design techniques and methods in aid of shortening the cycle of product development. 快速设计技术是在当今企业为快速响应市场对产品多样化需求的制造模式下提出并发展起来的,是以缩短产品开发周期为目的的一切设计技术与方法的总称。
