摘    要:通过宁波新一代天气雷达对0414号台风“云娜”的多普勒雷达探测资料及其所提供的产品进行个例分析, 得出了一些初步的结果:该雷达对“云娜”的中心位置探测与舟山、温州雷达以及中央气象台综合定位基本一致; 通过大陈站、石浦站出现的极大风速与温州、宁波两部多普勒雷达测得的最大径向速度比较, 发现其独特的径向速度产品能较好地显示台风的极大风速情况; 探测到的反射率因子强度与雨强有较好的对应关系, 并就此讨论了Z-I关系。文章还对总降水量产品和实况雨量进行比较, 发现反演值只有实况过程雨量的50%左右。

关 键 词:台风    中心定位    回波强度    雨强

Abstract:Detect products of Ningbo Doppler radar during the period of typhoon Rananim are analysised. Results show that Rananim's center located by Ningbo radar coincides with the guidance from NMC, reports from Zhoushang and Wenzhou Doppler radar. Velocity products of the Doppler radar can describe the maximum velocity pattern of typhoon Rananim well when comparing the maximum radius velocities of Dopple radars in Ningbo and Wenzhou with the extreme wind speeds occurring at Dachen and Shipu weather stations. Precipitation intensity is in good relationship with products of the echo, their relationship is further discussed, STP is about 50% of the observation.
Keywords:Typhoon Locating the center Intensity of echo Rainfall intensity
