【摘要】 随着中国气象局与宁夏自治区政府重点工程—宁夏中尺度灾害性天气预警系统的初步建成,多普勒天气雷达、自动气象站已经投入业务运行,为进一步提高针对短时灾害性天气的监测预警能力提供了良好的硬件研究。在前期研究和多年工作的基础上,综合利用多普勒天气雷达产品、宁夏本地中尺度数值天气预报模式产品,通过物理量诊断分析、雷达气象学分析和卫星气象学分析,掌握了宁夏强对流天气时间与空间分布的精细结构、短时演变规律与发生机制。利用新一代天气雷达产品、静止气象卫星红外云图并结合其它气象资料进行定点降水预报,通过自动气象站网降水实况资料进行订正,建立适合宁夏本地天气气候特点的短时预报监测模型。以VISUALBASIC语言为主,通过多种语文混合编程,在WINDOWS平台下,以软件系统工程学理论为指导,通过气象业务网络环境的软件开发,初步建立起了方便、快捷、实用的宁夏短时预报业务平台系统。该系统以多普勒天气雷达资料为核心,结合其他多源资料,建立了集资料采集、整理分析、预报为一体,多种预报工具、辅助功能较为齐备,实用快捷的短时监测预警业务系统开放式框架,并于2004年汛期投入业务应用,初步满足了预报需求。更多还原

【Abstract】 Using Doppler radar data, productions of Ningxia local meso-scale numerical forecast model, by diagnosis analyzing, radar and satellite meteorological analyzing, the fine special and temporal structure of disastrous weather events in Ningxia and their evolvement, mechanism in short-term were investigated. Based on new generation radar productions, geostationary meteorological satellite data, and corrected by rain gauges, the precipitation forecast models were developed both for grid points and stations. With Visual Basic language, the Ningxia Short-term Forecast Operational Platform System was developed in windows system and local network environment. This system has been put into operation in Ningxia Meteorological Observatory since the inception of flood season in 2004, and primarily met the need of operational forecast.更多还原
