中文摘要: 新一代天气雷达系统(CINRAD SA)中,在应用各种气象算法识别强对流风暴时,由于两种体扫模式VCP11和VCP21的差异,导致其生成的产品有明显的不同。为了进一步说明两者之间的这种差别,建立一个与VCP21基本相同的模式VCP22,并对VCP11与VCP22/VCP21生成的产品进行了比较分析;结果表明:在对流性不强的层状云降水天气过程中,两种体扫模式下生成的产品基本上是一样的;而在强对流天气过程中,当距离小于150km时,VCP11和VCP21的产品有较大差别,这说明在较近距离出现强对流天气时,应当

Abstract:Two different Volume Coverage patterns are used for monitoring convective weather in CINRAD SA.Because of the difference in two VCPs, the products derived from base radar data through using meteorological algorithmsare different,too. In order to explain it,a new Volume Coverage pattern (VCP22) is established and the products from VCP11 and VCP22 are compared. It shows that the products had the same values in shallow convection and different values in deep convection within the range of 150km. Therefore,it is confirmed that VCP11-not VCP21-should be used when the deep convection is occurred within the range of 150km.
