智能网格预报时空协调一致关键技术研发

A research on the key technology of space-time coordination and consistency of intelligent grid forecasting

自2016年起,我国大力推进气象业务向“智能化、无缝隙、精准化”发展。2017年宁夏积极推进智能网格预报业务体系建设,在网格预报智能订正、主客观融合订正、格点/站点/落区一体化、灾害天气智能识别等方面开展了一些尝试,取得了一定的成果,目前各项成果均引入到宁夏智能化天气预报业务平台中。其中一项关键技术,是智能网格预报的时空协调一致技术。该项技术在主客观融合订正、格点/站点/落区一体化中发挥了重要作用。本文重点针对这一关键技术的设计思路和实现方法进行介绍、讨论。

Since 2016,Chinese meteorologists have promoted the construction of meteorological modernization vigorously centering on seamless,accurate and intelligent weather forecast.In 2017,Ningxia meteorologists promoted the construction of an intelligent grid forecast system actively and they had made some achievements for grid forecast technologies,for example,intelligent correction,subjective and objective fusion correction,grid/station/zone integration,and disaster weather intelligent recognition.Those technologies were truly applied to forecast platform.One of the key technologies was space-time coordination and consistency,which played a very important role in the intelligent grid forecasting.This paper mainly introduced the design ideas and implementation process of this key technology.
