江苏龙卷观测预警试验基地雷达网设计

Radon Network Construction of Tornado Observation and Early Warning Test base in Jiangsu Province

龙卷具有空间尺度小、生命史短、突发性强、破坏力大等特点,是强对流中致灾性最强的天气现象之一,尤其目前绝大多数的气象探测设备和探测系统都无法有效监测、追踪龙卷的发生发展和消亡。目前中国龙卷观测主要依靠新一代天气雷达网,由于雷达网间距大,扫描模式固定,对龙卷等小尺度天气系统监测能力有限。苏北平原有特殊的地形和气候条件,是中国龙卷发生最多的地区之一,江苏在龙卷易发地区建设雷达网,开展龙卷观测预警试验,探测龙卷形成过程中的精细化垂直结构,研究龙卷形成过程与规律,提升龙卷等强对流灾害性天气过程的预报和预警时效,促进龙卷观测、预报和预警的业务化发展。

The tornado has the characteristics of small spatial scale,short life history and great destructive power.The tornado is one of the most violent convective weather phenomena.At present,most meteorological detection equipment and detection systems are unable to effectively monitor and track the occurrence and extinction of tornadoes.China’s tornado observation mainly relies on the new generation weather radar network.,the monitoring capability of small-scale weather systems is limited due to the large distance between the radar network and the fixed scanning mode.The northern Jiangsu Plain has special topography and climatic conditions,and it is one of the areas where the tornado occurred most in China.Construct a radar network in the Jiangsu area where the tornado is frequently developed,carry out the tornado observation and early warning test,detect the refined vertical structure in the formation of the tornado,study the formation process of the tornado,improve the prediction of the severe convective severe weather process,promote the operational development of tornado observation,forecasting and early warning.
